Hi All,
I did the following that try to draw an bitmap that was create in the
new buffer, but my bit map draw on the screen was not correct. What's
wrong? Is the way that I use GdBitmap is corrected.
Tuan
MWIMAGEBITS *hbitmap;
int nWidth, nHeight;
int size, linelen;
nWidth = 200;
nHeight = 200;
GdFillRect(psd,0,0,500,500);
PSD newPSD = psd->AllocateMemGC(psd);
GdCalcMemGCAlloc(psd, nWidth, nHeight, 1, 2, &size, &linelen);
hbitmap = new MWIMAGEBITS[size];
MWBOOL result = psd->MapMemGC(newPSD,200,200,1,2,linelen , size
,hbitmap);
GdSetForeground(blue);
GdEllipse(newPSD,50,50,50,50, TRUE);
GdLine(newPSD, 0, 0, 100,100, TRUE);
GdBitmap(psd,100,100,200, 200,hbitmap) ;
