I don't know if we should use the LM_[G|S]etPixel messages here. IMO the messages don't have a long life if you ask me. It is a little strange if you look at all the other graphic functions we've implemented.

I think it would be nice if it is implemented through the API:

   function GetPixel(DC: HDC; X, Y: Integer): COLORREF; stdcall;
   function SetPixel(DC: HDC; X, Y: Integer; Color: COLORREF): COLORREF;
stdcall;

You can add these through the ApiWizz tool. Then only the GTKWinApi.inc parts needs to be filled in.

Hello,

Which is the sequence that is due to follow to implement something?

For example:
How one implemented the rectangles or the lines?
Which archives are modified first?

I am interested in drawing pixels (and apparently somebody more).

Also this can be useful to learn to implement other things.

Please to enumerate the steps, like is a boy who learns to walk.

That easy!
I thought that they were 501 steps :)

Tomorrow I will watch all that (1:00 AM ZZZzzz).

How to implement Canvas.Pixels..

If you you will see that the function GetPixel already exists so I'm not sure that it needs to be "implemented". Perhaps it simply needs to be debugged. In getpixel there is a CNSendMessage call that sends a LM_GetPixel message and a MSG variable to gtkobject.inc. The LM_GetPixel causes a call to GetPixel and in that function the PixColor of the TLMSetGetPixel should be set.

Again, I'm not sure that it's working but it is written already. The SetPixel is also written. Whether it's working or not I'm not sure. All we need is someone to debug it for us (put in a few writeln's and see what's coming out of it).

It's strange, isn't it? Line[to] works fine,but pixels don't!
