Form image copy

[windy]

I have managed to get the form background working (and it does not capture what is on top of the form )
and I can step through all the controls on the form OK
in a LOOP., but how do you then paint those constrols onto the bitmap?
anyone got any code snippets for capturing a control (e.g button1) on a form (like copyrect type thing)


just thinking out loud here
with the original code, the copyform code, at the start of this thread, I tried setting the form to be outside the screen area.....but then you end up with black for the part of the form that is outside the screen area (i.e I moved the form to the far right of the screen)
so how can you get the form to be repainted off screen and not be black?

I have a button, a label and an empty image on a form. The label is copied to the image, at proper position and size, when I press the button. On button event:

Code: [Select]


var
  startx,starty:integer;
begin
  startx := label1.left  * image1.width  div width;
  starty := label1.top * image1.height div height;
  image1.canvas.copyrect(rect( startx, starty,
         startx+ label1.width*image1.width  div width,
         starty+label1.height*image1.height div height
                             ), label1.canvas,
                                label1.clientrect);
end;

I have made a bit of progress.....I can now get the edge of the control drawn (i.e a line (box) of where the control is, is drawn!)
but not yet the actual surface of the contrl

This code maintains aspect ratio, change size of the image in order to become it proportional to the form.
