And, of course, if you don't already own Photoshop, Gimp can do most anything you need to do, though the learning curve is hard and the workflow isn't as efficient.

displaying Bitmaps correctly
Hello,
I'm desperatly looking for code samples on how to display bitmaps on TX.
I'm able to display a 24 color bitmap but the resolution is just bad.
I have several bitmaps I got from the web also 24 color and they display fine,
but the ones I create with photoshop do not display very good as the colors are
completly destroyed.
when I try to compare the structure of the bitmaps, there does not seem to be
any difference reported by photoshop but one displays fine and the other does
not.
So far I have had to settle for low res bitmap display but I would like to
update the application UI to use more modern bitmaps like the ones they use in
the home screen and really be able to use the TX's high resolution screen.
I'm using cw 9.3 and pilcr for development tools
This is the code I'm using to display the bitmaps
void drawBitmap(UInt16 Bitmap, UInt16 X, UInt16 Y)
{
MemHandle h;
BitmapType* bmpP;
Coord width, height;
WinHandle winH = WinGetDrawWindow();
WinDrawOperation oldMode;
WinPushDrawState();
h = DmGet1Resource(bitmapRsc, Bitmap);
bmpP = (BitmapType*)MemHandleLock(h);
oldMode = WinSetDrawMode(winPaint);
WinPaintBitmap (bmpP, X, Y);
MemHandleUnlock(h);
DmReleaseResource(h);
WinSetDrawMode(oldMode);
WinPopDrawState();
}
and this is the resource code
BITMAP splashBM
BEGIN
BITMAP screen_saver.bmp BPP 8 DENSITY 2 COMPRESS TRANSPARENTINDEX 0
END
Same code is used to display the Palm images I got from the web and the images
I created with photoshop
Can anyone help help?
Thanks a bunch
Luis,

RE: Bitmaps distorted in PODS
Hi, The solution was: Export the xrd file as a 24bit BMP file onto your desktop. Do NOT allow GIMP to write into the file hyperlinked from the resource HTML file. Then, open the resource HTML file in the resource editor. Open the bitmap that you wish to edit, and click Import. Pick the temprorary file created before and import the data. Voila - it works. The reason why I fucked up was that I used GIMP to directly edit the bitmaps as referenced by the resource HTML file. Once again - do NOT edit the bitmaps in the /rsc folders!!

Bitmaps distorted in PODS
Dear Colleagues, I have just made a not lovely discovery when trying to import existing xcf (GIMP) images into my PODS-based project. I created a structure of 16bit bitmaps in order to get the files saved into the hard drive. Then, I opened GIMP and copied the XCF pixel info into the BMP file and saved it in bitmap format. So far so good - the program gets built. However, when running the PRC (and when looking at the bitmaps in resource editor), the colors are totally distorted. Opening the bitmap in GIMP reveals correct colors... Anyone of you have any ideas?

Re: scrolling bitmaps?
A good way to work with bitmaps, is to store the images in an offscreen window. Also keep in mind, that offscreen window dimensions,(as well as others I suppose), can be larger than the physical dimensions of the screen. So create an offscreen window with dimensions to hold all your images, and tile your bitmaps onto this offscreen window. Now you can copy the appropriate rectangular portions from your offscreen window, to the window associated with your 'Main Form'. To scroll your image, use WinScrollRectangle. This API tells you which portion of your window is vacant due to scrolling. Fill in the vacant part of your scrolled rectangle by copying from the appropriate region in your offscreen window. You can use the scrollbar logic to help you scroll your window. If anyone is keen, I'll post some code to illustrate what I'm talking about. Although this method is not very efficient, it's easy. Also it will suffice if your prepared not to tear ring with the offscreen window size. To find out more about offscreen window's, bitmaps etc, search the FAQ for Games, Animation on the palm website.

Newbie q: POSE under Linux, Bitmaps et c
I hope this is the correct place to ask. How can I import my rom image to POSE under Linux? I finally got POSE to compile and it shows up with pictures and everything on screen. But: 1) Why did it take several hours to compile? (Should I have looked for an RPM-package instead?) 2) Why does it crash if I switch to other than default version and memsize in the menu? 3) How can I import the ROM-image? The docs say that if a file ends with .ROM then it is imported. I copied the ROM file (from my Palm V via cradle Rom-transfer and Windows version of POSE that I have working). Did that work? NO! Why? What am I doing wrong? 4) And how do I hot sync on Linux? At first I have to put something in the linux.conf file I guess, just to have the serial port working, and then a hot sync program. How and where? (red hat Linux 6.1 didn't even configure the printer, that took some time) 5) And while I have your attention: what is the correct way of drawing dynamically generated bitmaps? I can make a bitmap (using older technology that OS3.5 so that it works everywhere) by simply allocating memory (BitmapType + data in one chunk) then fill it in and then use WinDrawBitmap(p, x, y) and then free it. Is this the right way or must the object live afterwards, ie should I only MemHandleUnlock it? But WinDrawBitmap takes a pointer so it might not even have a handle. Or is the approach completely wrong for drawing dynamically generated bitmaps on screen? Should I make a static dummy picture of the same size in the form and then overwrite it with some system call?

Re: /-c/ Compression of bitmaps
Ah ha! The /-c/ (etc.) is used if the bitmap isn't in a family. For example, if I have a 2-bit (4 gray) bitmap and reference it directly, it'll show up as 1-bit (black and white) unless I begin the name with /-2/. However, if that image is in a family and is specified as 2-bits, then it'll show up in grays regardless of the name. In my app, the graphics are either black and white, or are supplied in a family (with bw, gray, and color). However, I had an occasion where the same gray image would be displayed on all platforms (3.0+). I had to use the /-2/ naming convention or put this single image in a family (putting it in a family cost 3k in prc file size).

Re: How to convert a 8-bits bitmaps to 4-bits Grayscale bitmaps
If you don't need a color conversion it's even more simple.
You need something like this:
void DrawBitmap(BitmapType *bmp)
{
UInt16 err;
BitmapType *myBmp;
UInt8 *src, *dst;
Int16 i;
myBmp = BmpCreate( bmp-width, bmp-height, 4, NULL, err );
if ( err != errNone )
return;
src = (UInt8*) BmpGetBits( bmp );
dst = (UInt8*) BmpGetBits( myBmp );
// convert from 8 bit to 4 bit grayscale
for ( i = 0; i bmp-width * bmp-height / 2; i++ )
{
UInt8 b, bHi, bLo;
b = *src++;
bHi = b 4; // 8bit - 4bit - we ignore 4 low bits
b = *src++;
bLo = b 4;
*dst++ = (bHi4) | bLo;
}
WinDrawBitmap( myBmp, 0, 0 );
BmpDelete( myBmp );
}
Very simple isn't it? What's the problem?
If the original bitmap has 0 value as black and 255 as white (standard
grayscale format) you need to invert it (just use ~(b4) in conversion).
For color original bitmap you should get RGB from the palette for every
pixel and convert to grayscale using formula like I wrote in my previous
letter.
Good luck,
Alex
PS. It's for PalmOS 3.5 of course. For earlier versions you have to write
your own Bmp() functions. But it's not difficult.

Displaying selfmade bitmaps on PalmOS 3.5
Hi
I still can't seem to render selfmade bitmaps to the emulator. I've looked
through the archives and tried the examples, but the image is still not
appearing. The display stays white in the emulator.
What's odd is that when I get to the memset below, I start to overwrite
memory. Doesn't BmpGetBits give me a pointer to the bitmap's data area that
I can then manipulate at will?
Here's what I am doing:
pBmp = BmpCreate(width,height,8,NULL,error);
if (pBmp) {
win = WinCreateBitmapWindow(pBmp, error);
}
ptr = (unsigned char *)BmpGetBits(pBmp);
for (i=0;iheight;i++) {
memset(ptr, i, width);
ptr += width;
}
WinSetDrawWindow(win);
WinPaintBitmap(pBmp,0,0);
BmpDelete(pBmp);

Re: displaying bitmaps
But I think the question is worth asking again because there few answer and no concrete examples. I have built a simple splash screen using the CWarrior Constructor. I have images that are 1bpp, 2bpp, 4bpp and 8bpp colour. I created a bit map family, and, on none of the devices does the bitmap display correctly. I started to work with WinScreenMode but it fails to return values for anything other than Color and Height on the Emulators. So I think this is a very poorly documented subject and significantly impacts the building of professional applications for the Palm.

What I didn't like about that solution is that the position of the bitmap is specified in the code.

Re: Creating thumbnails of full screen size bitmaps
Thanks for your reply! I was in search of some functions in some built-in
library that does this job fairly well. If all else fails, this will come handy!
scaling from 320x320 to 80x80 is just 4-1 scaling. it is not hard to implement.
for(row){
for(col){
read(16 pixels from src image at coords [row*4,col*4])
separate the 16 pixels into rgb parts
average all rgb parts
write one pixel to destination image at coord [row,col]
}
}

FTP of bitmaps
I have downloaded the signature++ sample program that I found on the palm
site. We have an existing application written that downloads text
information from the palm to a windows server via FTP (this FTP program was
also downloaded from a sample found on the palm site). We need to use FTP
because some of our customers have the device at their customers office, so
the hot sync program isn't available - just a modem.
I am looking for an FTP program that can transfer the bitmap created by the
signature program.
The main jest of the FTP program is:
for( i=0; i totalCnt; i++, recordNum++)
{
printf( . );//One dot for each record read
recordH = DmQueryNextInCategory( dbP, recordNum, 0
);
if( recordH == NULL )
{
done = true;
}
else
{
src = (PackedItemPtr) MemHandleLock(
recordH );
if( src != NULL )
{
item = (UnpackedItemPtr)
MemPtrNew( sizeof( UnpackedItem));
//item-locnID =
(src-itemID);
//item-itemID =
(src-itemID)+StrLen( (src-itemID)) + 1;
//item-qty = (src-itemID)
+ StrLen( (src-itemID )) + 1 +
//
StrLen( item-itemID) +1;
//StrPrintF( outBuf,
%s,%s,%s,%s,%s\n, item-locnID, item-itemID, item-qty, po, date );
UnpackRecord( item, src);
if( StrCompare( cust,
item-custID ) == 0 )
{
StrPrintF(
outBuf, %s,%s,%s,%s,%s,%s\n, item-locnID, item-itemID, item-qty, po,
date, item-custID );
NetUWriteN(
sock, (UInt8 *)outBuf, StrLen(outBuf));
totalBytes +=
sizeof(outBuf);
}
MemPtrFree( (MemHandle) item
);
}
MemHandleUnlock( recordH );
}
}
So, instead of doing a StrPrintF I would need to use something that puts the
binary data over the FTP. Any ideas?
Thanks in advance.

Using Form Bitmaps
I have a form to which I've tried to add a form bitmap, with the intent that it is supposed to appear as a background, with other things, including labels, fields, and buttons (with bitmaps) appearing in front of it. But what happens is that all of those end up hidden, with the form bitmap appearing in front of them, and that's all I see until I explicitly cause one of the gadgets to update. I am using the PODS Resource Editor, and there doesn't seem to be any way using it to specify layering of the visual appearance (order of drawing) of things in the form when it first appears (as a result of a FrmDrawForm() call). And I could find nothing having to do with that in the .xrd file, either. Is there any way at all (maybe using CodeWarrior?) to properly handle this? Jay Ts -- Every child is an artist.

OK, maybe if I rearrange the order of the definitions in the
AppResources.xrd file, it will change the drawing order.
I'll try it.
i played with it some time ago and i had problems with
fields, they didn't looked nice because they erased screen, so there was

with ugly white rectangles where field was
I wonder if this is the same as a problem I'm having. On newer devices,
sometimes fields aren't drawn properly, and the border area around them
(about 2 pixels on all 4 sides) shows through (acts transparent) to
show the form behind it. This happened when I used FrmDoDialog() to
put up a very simple form with one editable field and an OK button.
This does not occur on older devices (T|E or Zire {21|31|71}), but
I've seen it on the Z22(?), TX and LifeDrive (and probably others).
The behavior of my LifeDrive (actual device) matches what I'm seeing
on the LifeDrive simulator, so it's not just a simulator bug.
While running Gremlins on the simulators, I noticed it happens even
with some of Palm's own software, so I'm pretty sure it isn't just me.
In fact, it looks like a bug in the recent releases of Garnet 5.x.

Re: Using Form Bitmaps
Jay Ts, Hopefully, the backwards-drawing versions will all be prior to Palm OS 4, because there are no devices from that historical time period I feel I need to support. My recollection was that it was OS5 when it switched, not OS4. And that originally the objects drew in object index order (which I believe is the sequence the objects are defined in the resource file). But that when it changted it started going in reverse index order. In the back of my mind, I was thinking this may be a by-product of the OS5 conversion of the m68k resources to the native resources. But maybe it was OS4 when it switched. What I do remember for sure is that at some point it started acting exactly backwards, so you couldn't use the resource sequence to consistently control the behavior on all devices.

The easiest way to draw into a bitmap is to call WinCreateBitmapWindow(). That will give you a WinHandle back which refers to the bitmap. Then, you can call WinSetDrawWindow() with that WinHandle, and after that all your WinDrawChars(), WinDrawRectangle(), WinDrawLine(), WinDrawBitmap(), etc. routines will draw into the bitmap. If you want to modify the bitmap directly, you can do that too. But in that case, it is best to create it with the BitmapRsrc routines that you can get from the palmos.com developer knowledgebase. The reason for this is that when you call the BitmapRsrc routines, you get back a bitmap that is in a well-defined format, and that makes it safe to draw into it. If you just call BmpCreate(), there are no guarantees about the format of the bitmap that comes back, and the only thing that's safe is to use the system's functions to modify such a bitmap. - Logan -- For information on using the PalmSource Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
Stretch / squeeze bitmaps?
Hi, Is there a way to stretch or squeeze a bitmap with 'good' quality results? On Microsoft, there is something called StretchBLT() that I believe supports this. I believe I need a 3,5,7 Tap Filter. Does anyone know where I can get one of these? THanks, __ Switch to Netscape Internet Service. As low as $9.95 a month -- Sign up today at http://isp.netscape.com/register Netscape.
