RE: support for PS printer-specific options using PPDs
Jeremias, This topic is very interesting me. I am also stuck with the tray selection. Can I have the code for tray selection and OMR marks for patching PostScript file please? Thanks Mark -Original Message- From: Jeremias Maerki [mailto:[EMAIL PROTECTED] Sent: Thursday, 25 April 2002 22:32 To: [EMAIL PROTECTED] Subject: Re: support for PS printer-specific options using PPDs Being the one who wrote the PS renderer in the first place, I can comment on a few things: - The PS renderer, as it is now, is more of a proof of concept, than anything else. Some people are using it productively, though. - As you gathered, there are a few things that still need to be done. Here's the todo list from the PSRenderer's javadocs: Character size/spacing, configuration, move to PrintRenderer, maybe improve filters (I'm not very proud of them), add a RunLengthEncode filter (useful for Level 2 Postscript), Improve DocumentProcessColors stuff (probably needs to be configurable, then maybe add a color to grayscale conversion for bitmaps to make output smaller (See PCLRenderer), font embedding, support different character encodings, try to implement image transparency, positioning of images is wrong etc. And of course, there's the missing PPD functionality. - There's also another problem: XSL:FO does not provide any means to specify things like tray selection. These will have to be proprietary solutions. And that means some work as well. What's important here is to have mechanisms that can be reused for PCL later. - Conclusion: Any help is welcome! (Because I haven't got the time yet, to do it. At least, it's on my todo list, because we're currently working with the PDF renderer, then using Acrobat Reader to produce PostScript, which is finally patched with code for tray selection and OMR marks. And this is a suboptimal solution especially since the Acrobat Reader takes between 20 to 50 percent of processing time for a job.)

I'm thinking of moving to iText or FOP for #1, but there's one particular problem that I can't seem to solve. When the client prints letters, they always want the first page to print on letterhead paper and the second and following pages to print on plain paper. With PS, you have the ability to set printer-specific options like paper-tray/type, but PDF doesn't have this capability as far as I know (I've read both specs pretty carefully). Unfortunately, it's not a clean switch trays every page situation, because some letters end up 3 pages rather than 2 (longer address, extra paragraph, etc.). So there's no way to render PDF ---ghostscript-PS, adding change trays every page to the PS at the end. In other words, I have to add the use tray x flag at the time of rendering, which means I must render to PS rather than PDF. Ideally, I would be able to use FOP and grab the proper use tray x flag from the PPD for the HP printer I'm using - I've even looked at a Canon machine called the imageRunner 5000 that allows you to set flags for switching trays, stapling, and folding (which would be nice for 1000+ person mailings). From checking the main fop page and the fop-dev archive, it seems that PS output in general, and any PPD capability specifically, is pretty far off. From what I can tell, renderX doesn't have PPD features either. Does anyone have any other ideas? Nathan Cheers, Jeremias Maerki
RE: block question in multi columns area
Hi, Xavier Part of this I can speak about...when I put in an algorithm for column rebalancing (the equilibration you refer to, on other words) it was very crude, really nothing more than a placeholder.

Possible thread-safe issue with fonts
Hi, I'm running cocoon 2.1dev under tomcat 4.04b2 with JDK 1.3 and FOP 0.20.3. My cocoon app is generating a PDF using FOP. I use and embed a font in my generated PDF file with the following in my userconfig file: font metrics-file=d:/fonts/font_dynamo.xml kerning=yes embed-file=d:/fonts/dynamo.pfb font-triplet name=dynamo style=normal weight=normal/ font-triplet name=dynamo style=normal weight=bold/ /font This all works fine and dandy under normal usage, I get the dynamo font embedded in my PDF and all is well. However if I run a load test (20 concurrent processes) on the same app. I get the following error appear in my tomcat log files: 2002-04-26 15:25:20 ERROR (2002-04-26) 15:25.20:375 [fop ] (/cocoon/invoice.pdf) HttpProcessor[80][11]/MessageHandler: unknown font dynamo,normal,normal so defaulted font to any Not for every hit, but for some. So I'm guessing that there is some sort of problem with resource sharing. That is, could FOP not be thread safe as far as accessing this file? Or if the file is loaded into memory once, could there be multi-threading issues with reading from wherever it is stored in memory? Anyone got any ideas? Chris.

Re: Possible thread-safe issue with fonts
It sounds like it is a threading problem. Do you get any messages like: Failed to read font metrics file ... It would appear that two threads could be reading the font metrics file at the same time. Accessing the file is done through the parser so we don't know what it is actually doing and it depends on the parser. I think each time it is a new data set in memory so it probably is not that.

Re: block question in multi columns area
Thank you Arved :) In the case of arbitrary contents on a cocoon plateform, it would be very very interesting to equilibrate the bloks, mine are small because of the carriage return : it's not confortable to make blocks just to simulate carriage return. I'm not enough confortable with this project, to help you, but I would like to help the french community, by translating a part of the documentation.

Re: Is FOP Actively Being Developed?
Hi L Rutker, Of course this is happening. Anyone who has read the XSL-FO specification would know about half of the problems we are facing. I suspect what you are really asking is for noticeable signs of progress for the user. All I can say is that this will happen when it is possible. As a rough guess for the development release I think it will take about 320 hours of work involving core knowledge plus another roughly 320 hours of non-core functionality. How this relates to people and dates is unknown. (these estimates could be way off, I would need to break it down further and monitor progress to get a better idea) Regards, Keiron Liddle.

Re: Spaces and precedence
Hi. Here is the (pruned) FO I get as an result of my xsl transformation. What I wanted to do was suppress additional space between two headlines that directly follow each other. fo:flow flow-name=xsl-region-body !-- preceeding blocks -- !-- block one -- fo:block break-before=page id=h1_6 space-before=50pt space-after=20pt space-after.precedence=1 7.Leistungsspektrum /fo:block !-- block two -- fo:block space-before.minimum=0pt space-before.precedence=2 id=h2_1 space-after=20pt space-before=50pt 7.1 Einzelplatzscanner /fo:block !-- succeeding blocks -- /fo:flow Block one := A Block two := B My understanding of the spec: A and B are stackable areas, have no borders or padding and are not reference-areas (block-progression-direction inherited from parent, no indents specified). A and B have a block stacking constraint S according to rule 3a. in chapter 4.2.5 Space Resolution: S1 := space-after=20pt precedence=1 S2 := space-before=50pt precedence=2 S'' := S1 and S2 In this case: S' == S'' because S'' does not contain line-area traits. The resolved space-specifier S would suppress S1 because it has a lower precedence than S2 (point 3 in 4.3.1). Do I get that right? FOP would not suppress anything and just add all spaces. TIA! Ralf

Re: page count
Henrik,
Your .fo file is an XML document. So, you need to write an XSL that can
rewrite the .fo document with some minor changes. Lets say you follow my
suggestion and your first XSL generates an .fo with fo:inline
placeholder=PutTotalPagesHere1234/fo:inline in those spots where
you want the page total. (. . . hm that is a tough problem isn't it?)
OK. You have to then render the document using FOP because FOP is the
only thing that's going to know how many pages are rendered. You'll have
to capture the total number of pages from FOP using that Java variable
which I saw referred to in a post about 3 weeks ago (anyone?) and then
rewrite the .fo using an XSL like this. Passing in the value for the
number of pages as a parameter to your stylesheet. I use saxon and the
command line is something like
saxon -o output.fo input.fo rewrite.xsl TotalPages=24
There's a Java interface on most XSL processors that allow you to do the
same thing. (Or, you could dynamically generate this XSL with the number
of pages embedded)
