The picture box is in a panel with autoScroll = true, so that scroll bars appear when the picture is larger than the panel.

First of all, this is not about making the PictureBox control transparent. It's about bitmap transparency on the fully opaque "canvas". The PictureBox will always have the size of 300*300 with white background. No transparency is needed for the control. What I need is the way to draw the transparent rectangle (or whatever else) onto th...

How do I do that in C#? :) Thx! ...
There seem to be many picturebox questions out there, but I haven't found any that deal with changing the contents of a picturebox to a bitmap that was not simply loaded from file. My application takes an array of bytes and generates a bitmap from them. I really want to avoid writing to a file as an intermediate processing step. Becaus...
