Question:
I’m developing a VB program that requires manipulation of pictures. I can read them in and display them without any problem, but I have no way (that I can find) of accessing individual pixels.
I need to be able to read each pixel’s RGB value, possibly altering it. Please help!
Answer:
You can do this one of two ways. The simplest, albeit the slowest, is with pure VB. Take a look at the Point Method (in your Help file), which is used to read the RGB value of a pixel. To set the color of a pixel, use the PSet Method.
The other alternative, which is indeed quicker, is to use the SetPixel and GetPixel APIs.
