When adding a Scanline in a crossplatform way, you will never get
that performance. TRawImage or TLazIntfImage have better ways to
implement this.
thats not true, with opBitmap i get the same Scanline perfomance as
in Delphi. I have made an simple video processing tool last week
with it that compares 2 images in 640x480 from an camera in realtime
!!!
Did you manage that on gtk/linux and carbon/osx too ?
gtk yes, carbon not tested
I'll look at the source. I wonder what performance gain a scanline will
bring over using a rawimage.
Anyway I see some options for supporting a scanline, in cases that the
bitmap is not selected in a DC
Just had a look at the 1.5 sources and that way I can implement it too.
