Hello Everybody,

I'm writing some code to display a computed image (I need to show the
result of a simulation).

I didn't find the reference documentation for the object then I
decided to ask!

I computed the Pixels values and saved them in a square (size of the
image) array of integer.
I created a TImage control on a form.

I'm not able to find the way to set the pixels in order to display a
color I will made equivalent to the value found in the array.

i populated the pixels property of the bitmap canvas but nothing
happens

may you help?


Thanks Roberto

Did you set Bitmap Width/Height before that?

object?
