Re: Why autoSizeColumn probably needs java.awt.headless=true
Rober, To calculate column width HSSFSheet.autoSizeColumn uses Java2D classes that throw exception if graphical environment is not available. However, some tasks such as computing text layout can be done in a headless mode, that is in the absence of graphical environment. To use headless mode you must set the following system property: java.awt.headless=true either via -Djava.awt.headless=true startup parameter or via System.setProperty(java.awt.headless, true). As Dave mentioned, there can be slight differences in the result: - Native graphical toolkits (WinXP or Unix with X11) are always more precise than the headless toolkit. The way the font metrics are calculated may be different in headless and headful modes. Moreover, it may different on different platforms, i.e. there can be minor differences between text metrics calculated under Solaris and under WinXP. That is why projects that require high-precision, platform-independent graphic calculations use their own mechanism to measure text (for example, Apache FOP). I don't think it's an issue in our case. Auto-sizing in Excel is a rough operation - user needs to APPROXIMATELY set column width to fit the text. - If some of the fonts are not available, JDK uses the default font. So if any fonts are missing in production you need to install them and copy font files to $JAVA_HOME/jre/lib/fonts/. P.S. It's good you raised this question. I'm going to update the docs to reflect it. Regards, Yegor DF Rober, DF As Andy says ask on the list. DF In your Tomcat startup on the unix server you need to be sure to set DF the following property - DF -Djava.awt.headless=true DF Do that and all should be good. DF If you notice slight differences in widths between windows and unix DF that may be due to the fact that autoSizeColumn uses fonts to do its DF magic. (Which is why it needs the graphic environment) So, then you DF might want to install fonts into /usr/java/jre/lib/fonts/ on the unix DF box. If you get stuck with that then you can ask again - Yegor can DF explain the exact rules.

Re: Need to merge PPTs
Hi, Unfortunately merging ppt slides is not as simple. PPT format has a global area where it stores the data shared among slides such as image data, fonts, etc. If you copy a slide with an image you must put the image data into this global area. The same thing is with text boxes. While copying text data you need to make sure all the fonts are registered in the ppt. So you see, it's not just copying of the raw data from source into the output. Anyway, I think HSLF has enough capabilities to do what you need. To me the task looks like replicating the source ppt. For each of the source slides you need to read shapes and re-create them in the target ppt. As you noticed, we don't yet support all the different shapes but it's not an issue for you. You don't need to interpret the shape properties and know the meaning of each of them. All you need is to copy ALL the shape props. If you are willing to contribute, welcome! It's not very hard to implement although it requires some knowledge of the ppt format. You can count on my help. Regards, Yegor JTS Hi! JTS We need to merge several PPTs into a single PPT -- each of the JTS original PPTs has a single slide with some simple shapes and images, JTS and each slide just needs to go straight into the output PPT. I JTS noticed an earlier thread on this topic saying that it's not quite JTS supported because HSLF doesn't yet support all the different complex JTS shapes. How close is it now? We're willing to contribute code if it's JTS close. In particular, I'm curious, is it possible to just copy the raw JTS data pretty directly from each source PPT into the output, without JTS necessarily knowing anything about the particular shapes and images JTS being used? That is, can we achieve the specific need of merging PPTs JTS without actually implementing all the different shapes and images in JTS HSLF?

Re: Computing anchor size for easy image insertion?
There isn't an easier way do scale images.
There was a discussion recently about scaling.
Excel measures images in units of 1/256th of a character width of the
default font. Conversion from these weird units to pixels is not
trivial. It's the main problem.
I have ideas how to add such support. Check POI in a month or two.
There is a chance I will commit it.

ÒÁV Hi all,
ÒÁV I'm using Jakarta POI 3.0-alpha3 to write an Excel spreadsheet with
ÒÁV images and I'm having some trouble computing the HSSFClientAnchor
ÒÁV size.
ÒÁV At the moment I try to manage it by adding column widths and row
ÒÁV heights until I reach approximately the size of the image in cells,
ÒÁV and then set up dx and dy, but I can almost never get it to work
ÒÁV perfectly and images are never exactly at 100%.
ÒÁV Is there an easier way to do this? I have searched around in google,
ÒÁV groups and google code search but couldn't find anything useful. How
ÒÁV do you people do this?
ÒÁV Thanks a lot!
ÒÁV Below is a snippet of my code. Basically, you give the starting row/
ÒÁV col position of the image you want to insert and it goes around adding
ÒÁV row/column sizes into imgHeight and imgWidth until their values are
ÒÁV equal to or greater than the size of the image. If they're greater, it
ÒÁV substracts one row or one column, depending on what was greater, and
ÒÁV puts the remaining pixels on dx or dy.
ÒÁV protected int addImage(HSSFWorkbook wb, HSSFSheet sheet,
InputStream
ÒÁV img, int numRow, short numCol) {
ÒÁV int x1 = 0;
ÒÁV int y1 = 0;
ÒÁV short x2 = 0;
ÒÁV int y2 = 0;
ÒÁV int row1 = numRow;
ÒÁV short col1 = numCol;
ÒÁV int row2 = numRow;
ÒÁV short col2 = numCol;
ÒÁV ImageData d = new ImageData();
ÒÁV int idx = loadAndConvertPicture(img,wb,d);
ÒÁV int imgHeight = 0;
ÒÁV int imgWidth = 0;
ÒÁV while(imgWidth d.getWidth() || imgHeight d.getHeight()) {
ÒÁV if(imgWidth d.getWidth()) col2++;
ÒÁV if(imgHeight d.getHeight()) row2++;
ÒÁV if(imgWidth != d.getWidth()) {
ÒÁV int colWidth = (int)
ÒÁV (sheet.getColumnWidth((short)col2)/48);
ÒÁV if(imgWidth+colWidth=d.getAmplada()) {
ÒÁV imgWidth +=colWidth;
ÒÁV } else {
ÒÁV col2--;
ÒÁV x2=(short)(d.getWidth()-imgWidth);
ÒÁV imgWidth=d.getWidth();
ÒÁV }
ÒÁV }
ÒÁV if(imgHeight != d.getHeight()) {
ÒÁV int rowHeight;
ÒÁV HSSFRow row = sheet.getRow(row2);
ÒÁV if(row != null) rowHeight = (int)
ÒÁV row.getHeight()/20;
ÒÁV else rowHeight = (int)
ÒÁV sheet.getDefaultRowHeight()/20;
ÒÁV if(row == null) row =
sheet.createRow(row2);
ÒÁV if(imgHeight +rowHeight=d.getHeight()) {
ÒÁV imgHeight +=rowHeight;
ÒÁV } else {
ÒÁV row2--;
ÒÁV y2=d.getHeight()-imgHeight ;
ÒÁV imgHeight =d.getHeight();
ÒÁV }
ÒÁV }
ÒÁV }
ÒÁV (note: variable and custom method names are translated since I'm not
ÒÁV coding this in English; there might be a bug in there somewhere due to
ÒÁV this translation. My apologies if this is the case.)

Re[2]: hslf way of getting slideshow text language
h This led me to believe that this atom holds the information I seek. It h is also the only place that language information in mentioned in the h spec.

Re: hslf way of getting slideshow text language
4010 is TextSpecInfoAtom. It stores special format runs that can't be described by normal style records. For example, if a part of a string is a hyperlink this info is stored in TextSpecInfoAtom.

Googling up and CG searching both through scratchpad hslf code and file format specs from CG wotsit gave me no useful information.

Re[2]: Embedded images
SJ Did you use a as the default character for any reason? Is that a standard SJ assumption to make? It's not documented. Just a guess :) Another variant is '0' but I can't tell for sure. It requires experiments. SJ There seems to be a bug with HSSFSheet.getColumnWidth(). According to the SJ javadocs, it should return the width of a column in units of 1/256 of a char SJ width. This is ok if the column width has already been explicitly set with SJ setColumnWidth(), but if not, it returns the same value as SJ HSSFSheet.getDefaultColumnWidth(), which is measured in characters. So I'm SJ getting the value 8 returned from getColumnWidth() for columns that haven't SJ had their width changed. Is this a known issue? Looks so. Bug 25496 reports on it too. The fix is trivial but it can affect existing code. Any programs that assume getDefaultColumnWidth() returns 8 will be broken. I will look into it on the weekend.

Re[2]: What is the state of the project?
I doubt if there are any pure Java VBA interpreters. (there can be implementations based on various Java-COM bridges). Creating a VBA interpreter is out of scope of the POI HSSF project but some really useful functionality can be added. I mean to add the following: - read VBA modules using POI. AFAIK, VBA modules are stored as POIFS entries. Did anybody investigate it? - be able to programmatically inject a VBA module in XLS (or modify an existing VBA module). Yegor TM Unfortunately, the ability to invoke a macro may be a requirement. That TM said, does anyone know of another Java-Excel project (e.g. JExcelAPI, TM Pagos spreadsheet component) that does include a VBA interpreter? TM Tom TM PS.

Re[2]: Master sheet handling
Hi Aha! You are doing it wrong. RichTextRun._getRawParagraphStyle() returns the collection of the OVERRIDDEN style properties. If the properly is not there, you should examine the master sheet. A good example is RichTextRun.getCharTextPropVal(). If a character property is not found it searches it in the master sheet. P.S. I don't recommend you to use the accessors to low-level style records. Be careful, this code is subject to change. Or use it only as a temporary solution, until the proper classes appear.

What we learn about it we put in the following doc: http://jakarta.apache.org/poi/hslf/ppt-file-format.html It's far from complete, as always other tasks have higher priority then documenting :). Some time ago MSDN (prior to 1998) contained partial docs about the ppt format but later they excluded it. What features you are interested in?

Re: [HSLF] Indentation level identification
Hi,
TPN Is there any other way to identify the indentation level for a given
TPN RichTextRun?
Unfortunately you can't retrieve the indentation level for a
RichTextRun. It's not supported by the current code.
Indentation level is stored as a 2-byte paragraph property in the
style record. Initially we thought that this value is 'safe to
ignore', it was always 0 in out test ppt files. In fact it stores the
indentation level and can be a number in the range 0-4 (there can be
up to 5 indent levels in PowerPoint).
I'm not sure if it is an easy fix and I'd like to hear Nick's opinion.

TPN Hi,
TPN I need to identify the indentation level of a text in a TextBox. For this
TPN I created a method in the RichTextRun class as follows:
TPN public int getTextOffset(){

TPN }
TPN Assuming that the property name that holds this information is
TPN text.offset, is it?
TPN When I call it from my main class, it returns -1. I know this is because
TPN the RichTextRun inherits the property from the Master.

Re[2]: [HSLF] Indentation level identification
Nick,
In StyleTextPropAtom.setParentTextSize when we read paragraph
properties we ignore the 2-byte value before the paragraph
properties:
// Fetch the 2 byte value that is safe to ignore as 0
short paraIgn = LittleEndian.getShort(rawContents,pos);
pos += 2;
In fact it stores the indentation level.
What is bad, that this value is re-setted to 0 when a slide show is saved and
the indentation information is lost. Try to re-save a ppt with indents
and see that they are lost!
I'm not sure I can quickly fix it, have a busy time last days :).

Re: RES: Extracting Tables from PowerPoint
If you need the text in cells use TextRun.getText().
Does it return the correct text?
TextRun.getRichTextRuns() is supposed to return an array of runs of
text with the same styling. The size of the array of RichTextRuns should be
greater than 0.
Could you attach your ppt file and we will look at it?
Yegor

G Using your example below, I was able to identify the number of cells

Re: non {png,jpg} images
Hi, Supported image formats in PPT are: EMF, WMF, PICT, JPEG, PNG and DIB. If you insert pictures in other formats PPT may convert them, for example, into JPEG or PNG and store the converted data. I confirmed that on Windows BMP is converted into PNG. Could you send your PPT with TIFF? I would like to examine it. PNG and JPEG images are organized in a similar way: 25 byte header + raw image data. Probably this rule breaks for other formats. Probably there are some features with ppts created on MAC. You never know it with PowerPoint :) Regards, Yegor - To unsubscribe, e-mail: [EMAIL PROTECTED] Mailing List: http://jakarta.apache.org/site/mail2.html#poi The Apache Jakarta Poi Project: http://jakarta.apache.org/poi/

Re[2]: PPT Pictures
There are two ways to retrieve images from a ppt file:
1. Use HSLFSlideShow.getPictureData().
This method always returns the content of the image stream,
It doesn't know if the images are used in the slides or not.
I would say it corresponds to physical level, not to the logical, i.e.
it returns images that are stored in the ppt file, not the ones that
are actually used.
As Nick says, if you edit your ppt with 'incremental save' option
enabled, HSLFSlideShow.getPictureData() can return previously deleted
images which will be gone on next full resave.
2. Iterate over the shapes in a slide and collect Picture shapes.
This approach guarantees that you get only those Pictures that are
actually used:
Slide[] slide = ppt.getSlides();
for (int i = 0; i slide.length; i++) {
Slide sl = slide[i];
Shape[] sh = sl.getShapes();
for (int j = 0; j sh.length; j++) {
Shape shape = sh[j];
if (shape instanceof Picture){
Picture picture = (Picture)shape;
PictureData pict = picture.getPictureData();
byte[] data = pict.getData();
int type = pict.getType();
if (type == Picture.JPEG){
FileOutputStream out = new
FileOutputStream(_slide+j+.jpg);
out.write(data);
out.close();
} else if (type == Picture.PNG){
FileOutputStream out = new
FileOutputStream(_slide+j+.png);
out.write(data);
out.close();
}
}
}
}

Hi
For instance, if there are 3 pictures, being 2 of them the same picture,
the returned vector length is 2.
It's how it is supposed to work. HSLFSlideShow.getPictures() returns the
actual array of images contained in the presentation.
Each image is included only once regardless of how many times you have it
in the slides.
What can I do to get the real images number?
It looks like you need the number of images shapes, not the number of
actual images contained in the ppt.
See the code:
SlideShow ppt = new SlideShow(new HSLFSlideShow(images.ppt));
//images contained in this slide show
PictureData[] pict = ppt.getPictureData();
//get the number of image shapes
int imageCount = 0;
Slide[] slide = ppt.getSlides();
for (int i = 0; i slide.length; i++) {
Shape[] sh = slide[i].getShapes();
for (int j = 0; j sh.length; j++) {
if (sh[j] instanceof Picture) {
Picture p = (Picture)sh[j];
PictureData pdata = p.getPictureData();
imageCount++;
}
}
}
Since the same image can be placed on several slides imageCount may not
equal to pict.length.

Re: POI issue
Hi,
Your code is almost correct.
The last lines must be as follows:
FileOutputStream out = new FileOutputStream(C:/Test/Presen.ppt);
ppt.write(out);
out.close();
I.e. To create a new PPT you call SlideShow ppt = new SlideShow();
To write it to a output stream call ppt.write(out);
HSSFWorkbook has nothing to do with the PPT stuff. It's about XLS generation.

String text = box.getText();
String font = box.getFontName();
int size = box.getFontSize();
...
}
}
Warning: In the current implementation you can get text attributes only if
they are explicitly set. For example, if you don't change the default
font size box.getFontSize() return -1 which means n/a. In this case PowerPoint
uses the default font size which is stored in special container
TxMasterStyleAtom which is not decoded yet.
Also the object model for working with character/paragraph attributes
is likely to change. Current code is rather demonstration of
capabilities, not the final version.
Some documentation is available at
http://jakarta.apache.org/poi/hslf/how-to-shapes.html

Re[2]: org.apache.poi.hslf.model.Slide
The number of the first slide is stored in DocumentAtom. In PowerPoint you can change it in the Page Setup dialog. If we get slides in the correct order then getSlideNumber should return DocumentAtom.firstSlideNumber + idx; where idx is 0-based index in the array of slides. You can play with this setting and see how slides are numbered in a ppt. I'm not 100% sure this rule always works. I wonder if it is possible to have gaps in numeration. Did you ever see such ppt? Regards, Yegor NB Firstly, please use poi-user for questions like this.

We haven't figured out where powerpoint stores the slide number, NB and we're starting to suspect that it doesn't actually store it as such NB Assuming Yegor's ideas on the slide ordering (see bug #39547) do hold true NB when we test them on lots of files, then that code may help NB Nick NB - NB To unsubscribe, e-mail: [EMAIL PROTECTED] NB Mailing List: http://jakarta.apache.org/site/mail2.html#poi NB The Apache Jakarta Poi Project: http://jakarta.apache.org/poi/ - To unsubscribe, e-mail: [EMAIL PROTECTED] Mailing List: http://jakarta.apache.org/site/mail2.html#poi The Apache Jakarta Poi Project: http://jakarta.apache.org/poi/
Re: HSLF - problem getting correct style of richTextRuns
Hi In HSLF we only have initial support for rich text runs. You can read style attributes only if they are explicitly set. If style is not set explicitly it is taken from a special container TxMasterStyleAtom which is not implemented yet. I think I know how to handle master character styles. This is in my TODO list. Paragraph styles are more tricky. PPT inserts a special symbols in the text like 0x0B to mark the beginning of each paragraph. There is a ruler record which defines indentation of each level but I didn't decode it yet. MSDN says Special parsing code is needed to parse content of this atom so I have to guess and it takes time. Regards, Yegor KR Hi, KR I'm using the HSLF, and I noticed the following problems: KR 1. If I have a slide, In which I just printed some lines in the KR default styling (I didn't manually set the size or font of the KR characters), then I get -1 and null when using KR richTextRun.getFontSize() and richTextRun.getFontName() . KR When creating the presentation - if I press enter in order to start a KR new line (with a bullet) and press tab and write (in this case the font KR size is getting smaller by default), I still get no difference in the KR fonts sizes. KR It looks like this: KR * First line - real size 32 (shows size -1 or the last font size KR I set) KR * Second line - real size 32 (shows size -1 or the last font KR size I set) KR oThird line - real size 24 (shows size -1 or the last font size KR I set) KR Is this a bug or can I get this information in another way? KR 2. I can't see in any way that text begins with one tab right. Is KR there a way to get this information? KR Please help me with the above problems. KR Thanks, KR Karajo. - To unsubscribe, e-mail: [EMAIL PROTECTED] Mailing List: http://jakarta.apache.org/site/mail2.html#poi The Apache Jakarta Poi Project: http://jakarta.apache.org/poi/
Re[2]: Is PPT Merging possible with HSLF
Hi Poornima,
OK, since you want it right now here it is:
//source ppt
String srcppt; //path to the source presentation
SlideShow src = new SlideShow(new HSLFSlideShow(srcppt));
//target ppt to copy slides to.
// In this example it is a new ppt but you can add slides to existing
one.
SlideShow tgt = new SlideShow();
Slide[] sl = src.getSlides(); //get slides
for (int i = 0; i sl.length; i++) {
Slide slide = tgt.createSlide(); //create a slide to copy shapes to
//copy shapes from the source ppt
Shape[] sh = sl[i].getShapes();
for (int j = 0; j sh.length; j++) {
slide.addShape(sh[j]);
}
}
OutputStream out = new FileOutputStream(merged.ppt);
tgt.write(out);
out.close();
This code is new, it was commited a month ago and most likely there
are bugs. Text formatting may not be preserved fully. Complex shapes
like tables may not work.
The example above is just a demonstration of capabilities (a
technology preview). There are lots of undone stuff.
Let me know if you have problems with a particular type of shape.
Regards, Yegor Kozlov
PA Thanks Yegor,
PA Could i get the example you were talking ablout?
PA Thanks a lot,

It won't work if your source PPTs contain complex shapes (Tables or custom

Re[2]: problem with HSLF slides and RichTextRuns
3. I would like to know what pictures belong to what slide. Is it
possible? (I didn't find a way to do it) if not, when will this be
possible?
NB I don't believe it is currently possible. It should be fairly easy to
NB implement, once we know how powerpoint matches pictures to slides. Until
NB we know that, we can't code the functionality!
NB Nick
Hi
Nick, it is possible! This functionality new. I added it just a couple of weeks
ago. Below is an example how to know what pictures belong to what
slide:
SlideShow ppt = new SlideShow(new HSLFSlideShow(filename));//source
ppt
//array of picture data contained in the presentation.
//it has global scope since the same picture can be included in
multiple slides
PictureData[] pict = ppt.getPictures();
Slide[] slide = ppt.getSlides();
for (int i = 0; i slide.length; i++) {
Slide sl = slide[i];
Shape[] sh = sl.getShapes(); //get all shapes for this slide
for (int j = 0; j sh.length; j++) {
Shape shape = sh[j];
if (shape instanceof Picture){
Picture picture = (Picture)shape;
//i-based index of the actual picture data
int idx = picture.getPictureIndex();
PictureData pictdata = pict[idx-1];
//raw data.
byte[] data = pictdata.getData();
BufferedImage img = ImageIO.read(new
ByteArrayInputStream(data));
//draw image of save it to a file or do whatever you want.
}
}
}
}
Note, current implementation supports only JPEG and PNG formats.
WMF and Macintosh PICT are not yet supported.

Re: ayuda, para ver power point!!
No, you can't do that. I'm not sure this functionality will ever present in HSLF. First of all, HSLF is meant for reading/writing ppt files, i.e. you can extract information about shapes, texts and other objects from a ppt file or you can create such ppt files on the fly. In future, I can imagine an utility based on HSLF which will build screen captures of PPT slides and save them as images. Regards, Yegor Kozlov l Greetings. I do not speak ingles. use translator.

Re[2]: Powerpoint and HSLF
Hi Nick NB Yegor - YA adding slides fix: alas the RefId wasn't as simple as NB (slide ID+2), it's actually the sheet ID from the PersistPtr NB stuff. I've fixed the code, and added some more tests to NB TestSlides to check it all Thank you. I'm going to do stress testing tonight. In my development I always create new PPTs from scratch and the rule (slide ID+2) always works. Now I see where I'm wrong.

Re: Image extraction
Hi I think I know how to extract images from a ppt file. PowerPoint stores images in a separate OLE stream named Pictures. Extracting image data from it is not difficult, I will commit the patch in a couple of days. Regards, Yegor DN Hi. DN I've been testing POI lately on Word, Excel and PowerPoint documents DN with the goal of extracting text from those document types, and I have DN to say that the scratchpad in the latest alpha is quite good for DN extracting text from even PowerPoint documents.
