Default Transparent color for bitmaps on cmd buttons
 

I was wondering if anyone else has had noticed this. It seems that
whenever I put a picture on a command button, the lower left corner
pixel of the image is set as the 'transparent' color for the button,
meaning the back color of the button shows through instead of the color
of the bitmap.

For example, lets say I have an bitmap of a blue circle on a white
background. If the lower left pixel in the bitmap is white, then the
white wont show up when the image is placed on a cmd button. If the
lower left pixel is blue, the blue circle will be transparent to the
background.

In essense, you can set the transparent color of an image by placing
the color you want to be transparent in the lower left corner pixel...
which is helpful to know.

Anybody else have this experience or can confirm/dispute this? Im not
sure if this is "new" news or not...but I couldn't find posts related
to it.
