Hi,
REALbasic 2007r1 Pro for Mac OS X 10.4.8
I use the following code to remove the Red part of the pixels from the passed
Picture:
surf = Pict.RGBSurface
If surf = Nil Then
// Stop here
Return // Exit silently
End If
// Remove the Green and Blue parts
For MapLoop = 0 To 255
RedMap(MapLoop) = MapLoop
GreenMap(MapLoop) = 255
BlueMap(MapLoop) = 255
Next
// Apply the change
surf.Transform RedMap,GreenMap,BlueMap
Of course - this is why I ask the question - I do not get what I wanted!
I tried - before writing this help message - to understand, but I failed
miserably. I tried wikipedia and some other developer helper sites (I saw code
to deal with colors, transform RGB to whatever / whatever to RGB and so on...).
But I only have a black wall in front of me when I want to go ahead on that
subject.
If there is a kind soule here (there are plenty) with the knowledge (the number
falls) and the pedagogy skill to explain (is there some body here ?) ?
[If so and if you have time, go ahead: explain, please]
Of course a link to a place this already exists is welcome :)
TIA,
Emile
