Hi!!!
I need to do something with a BMP but I can't find how to do it!
I'm going to explain what I need... Basically, I have a BMP picture and I need to close a part of it and save it as another BMP picture.
An example... I have pict1.bmp (640x240) and I want to close with a black rectangle the (10,10,100,100) coordinates. After it, I have
to save this changes in another BMP picture, pict2.bmp (640x240).
Could anybody help me? Any suggestions? I find the DrawRect function, but I don't know how it works... and I don't find any function to save it
as a BMP picture.
Thanks!!!!!
Miguel Angel.

Using DrawRect is correct. Another solution would be to draw a
region and then filling it with black. Which programming
interface are you using (e.g. COM, OCX, etc.)? I need to know in
order to provide you with more details.
Thanks,

I´m using COM interface. My problem now is that I know how to draw a rectangle with DrawRect, but I can´t save the new BMP with the rectangle... If I do Lead.save, the BMP saved it is the original BMP picture.

Set the DrawPersistence property to True to make the rectangle permanent on the bitmap.
