Yes, it is fairly easy, but you need to convert it to whatever the
destination format is. The following does pnm files (see
www.wotsit.org or any unix/linux system or the Gimp).
i = 32767;
t = DmNewRecord(dbR, &i, 3212);
bp = buf;
*bp++='P';
*bp++='4';
*bp++='\n';
*bp++='1';
*bp++='6';
*bp++='0';
*bp++=' ';
*bp++=' ';
*bp++='1';
*bp++='6';
*bp++='0';
*bp='\n';
DmWrite(MemHandleLock(t), 0, buf,12);
DmWrite(MemHandleLock(t), 12,
WinGetWindowPointer(FrmGetWindowHandle(FrmGetActiveForm()))->displayAddrV20, 3200);
MemHandleUnlock(t);
DmReleaseRecord(dbR, i, true);
(This is from one of my screen capture hacks).
It just happens that the internal screen and pnm formats coincide.
But the above is the general idea. Prepare a header, copy and
compress or format the actual image data for the destination format,
then store or send.
