Hi John

Create in what way? Do you have a source image, or are you custom drawing them?

Want to convert from a memorystream containing a bitmap to a memorystream containing a jpg image.

Thanks,

OK, then just use a TIEBitmap and use Read() to input the stream, then Write() to output it.

https://www.imageen.com/help/TIEBitmap.Write.html

Something like:


bmp := TIEBitmap.create;
bmp.ParamsEnabled := True;
bmp.Read( ms );

// Set your JPEG quality, etc.
bmp.Params...
bmp.write( ms, ioJPEG );
bmp.free;
