I found a post from Matthew Bevan at
http://www.escribe.com/computing/pcpqa/m75497.html that looked a bit easier.
I was able to further simplify his code to the following. Can anyone poke
holes at this code? - it appears to work for me :-)
void WinDrawCharsSmall(const Char *chars, Int16 len, Coord x, Coord y)
{
WinHandle tempWindow;
WinHandle oldWindow;
Err err;
BitmapPtr bmpP;
BitmapTypeV3 *bmpHDP;
// Step 1: Create an off-screen, low-density window.
tempWindow =
WinCreateOffscreenWindow(FntCharsWidth(chars, len),
FntCharHeight(),
genericFormat, &err);
bmpP = WinGetBitmap(tempWindow);
// Step 2: Switch to said window.
oldWindow = WinSetDrawWindow(tempWindow);
// Step 3: Draw the text to our temporary window.
WinDrawChars(chars, len, 0, 0);
// Step 4: Switch back to the original window.
WinSetDrawWindow(oldWindow);
// Step 5: Create a HD bitmap from the window.
bmpHDP = BmpCreateBitmapV3(bmpP, kDensityDouble,
BmpGetBits(bmpP), NULL);
// Step 6: Draw the temporary bitmap to the active window.
WinDrawBitmap((BitmapPtr)bmpHDP, x, y);
// Step 7: Free the temporary window and bitmap.
WinDeleteWindow (tempWindow, false);
BmpDelete ((BitmapPtr)bmpHDP);
}
Thanks...
