Ok a dumb question I not a C programmer I have an extensive image pgm written in Vb net. I used DC raw with
bm = Bitmap.FromStream(process__1.StandardOutput.BaseStream) process__1.WaitForExit()
works great
It just catches the stream and directs it to a bitmap

I have tried a gazillion ways to do this with libraw. I can get it to write file , tiff etc but no pipe back
Yes yes a better way would be some form of integration dll or something but this is beyond me

Any help would be great - and no poo on Vb thanks

I have managed a great pgm, content aware and stuff like that
