Thank you for your answer,
I am trying something, but it`s really not working, custom palette
implementation is very poor documented with no example at all, i didn`t find
anything on Internet neither. Can you help me with some simple example how
can i display bitmap done it in custom palette.
This is what i have done but it`s not working:
1. I have bitmap created with custom palette, 248 nuance of brown, and 8
standard colors. You wrote:
> If you make the bitmap only about 240 colors
> you can avoid changing any colors the UI uses.
Where can i find values of that standard UI 16 colors?
----------------------------------------------------------------------------
---------
2. From ACD PhotoCanvas i created .pal (PaintShop palette file) file from
bitmap, note that some other programs extract palette file with different
queue but same values, is this important :
------------- brown_custom.pal ------------------ (copy/pasted)
255 255 255 ---> first line of pal file
255 255 0
255 0 255
255 0 0
0 255 255
0 255 0
0 0 255
0 0 0
154 65 6
181 110 30
124 45 12
178 123 52
199 140 62
....
...
..
.
86 22 9
65 11 1
79 17 6
0 0 0 ---> last, 256 line of file
----------------------------------------------------------------------------
-------------
3. In RSC file i insert this:
BITMAPFAMILY ID 2800
COMPRESS
BEGIN
BITMAP "black_white.bmp" BPP 1
BITMAP "low_densiti.bmp" BPP 8 NOCOMPRESS DENSITY 72
BITMAP "hi_densiti.bmp" BPP 8 NOCOMPRESS DENSITY 144
BITMAPPALETTE "custom_palette.pal"
END
PALETTE ID 1000 "custom_palette.pal"
// both colored bitmaps created with custom_palette
----------------------------------------------------------------------------
------------------
4. In source insert:
h = DmGetResource('Tbmp', (int)bmpID);
ErrFatalDisplayIf(h == NULL, "Missing Bitmap Resource!");
bp = (BitmapPtr)MemHandleLock(h);
int size = MemHandleSize (h)/sizeof(RGBColorType);
WinPalette(winPaletteSet, 0, size,(RGBColorType*)bp);
WinDrawBitmap(bp, x, y);
MemHandleUnlock(h);
DmReleaseResource(h);
or:
WinPalette(winPaletteSet, 0, 16,
(RGBColorType *)MemHandleLock(h));
----------------------------------------------------------------------------
-------------------
When i done this color are messed up bitmap is green and black.
Can you tell me where i do wrong or if you have some advice or some simple
example, i will be very appreciative.
Thank you.
