I was trying to find the function of clear all my drawings after a mouse click.
I noticed that in the latest ImageLibEx.dll, there is a clear method to clear the drawing board. I was wondering whether you have that function in the imagelib.dll too.
No, just use ImageLibEx. It is a strict superset of ImageLib which was used with Erels' permission as the code base for ImageLibEx so you lose nothing but gain a lot.
