Hi,
REALbasic 2006r2
In a current project who create a Mask to the dropped Icon (max size:
128 x 128), I just added some color variations (replace the original
color by another) and I have fun with it.
But what is fast on 128 x 128 image is low, too low on a photo (Millions
of pixels)...
How can I ?
Change the cmy values of the pixel in a faster way ?
I actually use RGBSurface and change the Cyan value of a pixel by either
Cyan (!), Magenta or Yellow and so on... in a loop.
Since the loop change/replace | read/write all pixels of the image, it
takes time, long time...
Do you have a better (faster) REALbasic native solution ?
TIA,
Emile
In other words, inside two nested loops, I use RGBSurface.Pixel, get a
part of its cmy values and use only Cyan, Magenta or Yellow in the
replaced (still with RGBSurface.Pixel) pixel and assign the new color to
the image. That process is slow.
Using RGBSurface.Transform works fine for Brightness / Darkness / Invert
and some other things, but I am in front of a wall for what I want to do
now.
