I've recently 'tackled' this problem. You can't draw on an icon because
it has no canvas, so you have to copy it to a bitmap.
After that you can
create an icon from that bitmap again but you'll need a second bitmap as
a mask for the transparent parts (which is also something you shouldp
jeep in mind when copying the icon to the bitmap).

You can find a link
to an article explaining this on Earl Glynns page. Look at the icon
section at http://www.efg2.com.

Note, change your PixelFormat

BitmapIconA.PixelFormat := pf32Bit

hello elvinluis29, this is a rather complex thing to do, especially for 32 bit icons, and their Alpha channel byte in windows XP, but you might look at my Icons to file at


http://www.angelfire.com/hi5/delphizeus/saveicons.html

which has a provision for 32 bit icons

elvinluis29, a grade of C?

First, like Slick812 said, "it is a very complex thing to do".

Secondly, i believe we (Slick & I) pointed you in the correct direction. If you didn't like the answer, you could have responded saying that is not what you were looking for....explain further, and we would have helped further.

Thirdly, you only provided 20 points. Its not that great of a compensation for someone to spend lots of time on your question. Seeing your question is more of a Intermediate to hard level question, you may have wanted to boost your points to entice others to have an attempt at your question. There are experts like myself and many others, who really dont care about the points, and will make a stab at it regardless....

Fourth - Experts remember those who grade badly and in the future will be hesitant on answering posted questions by those who un-necesarily grade to the extreme.....
