I'm looking for the smallest (in terms of filesize) transparent 1 pixel image.

Currently I have a gif of 49 bytes which seems to be the most popular.

But I remember many years ago having one which was less than 40 bytes. Could have been 32 bytes.

Can anyone do better? Graphics format is no concern as long as modern web browsers can display it and respect the transparency.

In this post we'll look at the AlphaBlend() api and how it can be used for semi-transparent blitting. AlphaBlend() takes a source device context and a destination device context (DC) and combines the bits in such a way that it gives a transparent effect.
