Hello,
i am using ImageMagick++ to do that kind of work.
it sounds like it has been configured well, despite this, i got a black image from that conversion work :
Magick::Blob JPEGblob ( [iJPEGdata bytes], [iJPEGdata length] );
// Magick::Image ImageJPEG2TIFF ( JPEGblob );
Magick::Image ImageJPEG2TIFF;
ImageJPEG2TIFF.magick("JPEG");
ImageJPEG2TIFF.read( JPEGblob );
//
ImageJPEG2TIFF.write( WriteFileNameJPEG );
//
ImageJPEG2TIFF.magick("TIFF");
//
Magick::Blob TIFFblob;
ImageJPEG2TIFF.write( &TIFFblob );
Thanks in advance for any help you can provide me.
(including telling me that this is impossible, to avoid me wasting my time)
