Hi all,
Am trying to show a bmp image in a form . I need to set
transperency to the image to remove the unwanted image data from the
original image. ie; a pink border from the bmp. Please go through the
following code segment. The image displays without the pink image in
emulator. But in device on application selection, device reboots. The
issue mainly arises at BmpSetTransparentValue. How to deal with this
issue. Am using Life Drive and the IDE i have chosen is codewarrior for
palm.
void drawVisionLogo()
{
MemHandle bitmapHnd;
BitmapPtr bitmapPtr;
bitmapHnd = DmGetResource (bitmapRsc,Logo);
if (bitmapHnd)
{
bitmapPtr = (BitmapPtr)MemHandleLock (bitmapHnd);
RGBColorType transparentColor;
transparentColor.index=0; // if you change the (0,0,0)
transparentColor.r = 0x0; // value, the function
transparentColor.b = 0x0; // will not work!
transparentColor.g = 0x0; // why?
// BmpGlueSetTransparentValue((BitmapType*)bitmapPtr,*(UInt32
*)&transparentColor);
BmpSetTransparentValue((BitmapType*)bitmapPtr,*(UInt32
*)&transparentColor);
WinDrawBitmap (bitmapPtr, 35, 35);
MemHandleUnlock (bitmapHnd);
DmReleaseResource (bitmapHnd);
}
}
