I am developing an application specifically for the Tungsten W. The
application runs at 320 x 320 x 16 bits. (Note, I'm using pilrc/gcc on OS X)
I have a 320 x 320 x 24 bit BMP file in my resource. Constructor shows the BMP
properly. When I load the bmp to the screen The first few lines (probably
about 10 lines) are perfect... but then it disintegrates into random dots.
If I load a 160 x 160 x 24 bit BMP into the resource, I can load it perfectly
into the screen and it indeed fits in the upper left quadrant (and I also
tested drawing the 160 x 160 bmp at 0,0 and 0,160 and 160,0 and 160,60 and
indeed got a 2 x 2 of my 160 x 160 BMP on the 320 x 320 screen, so I think
I've got things setup ok).
When I go larger, it loads perfectly for a portion of the screen, and then
disentegrates into mush (e.g., a 250 x 250 image shows more perfect area before
disentegrating than a 320 x 320).
What am I doing wrong? Any help would be GREATLY appreciated.
Here is my code:
WinScreenMode(winScreenModeGet,&O_w,&O_h,&O_d,&O_f);
t1 = 320; t2 = 320; t3 = 16; b1 = 1;
WinScreenMode(winScreenModeSet,&t1,&t2,&t3,&b1);
WinPushDrawState();
WinSetCoordinateSystem(kCoordinatesNative);
if ((bitmapH = DmGetResource(bitmapRsc,1))) {
bitmapP = (BitmapType *)MemHandleLock(bitmapH);
bitmapPV3 = BmpCreateBitmapV3(bitmapP,kDensityDouble,BmpGetBits(bitmapP),0);
WinDrawBitmap((BitmapType *)bitmapPV3,0,0);
MemHandleUnlock(bitmapH);
DmReleaseResource(bitmapH);
}
WinPopDrawState();
