Possibility of changing a picture's background color

[DavidLee]

hello,

Using the attached tools , ICON Editor with CVI 7.1, I can draw an icon but always with a background color, I noticed that there is a function : SetBitmapData(), it seems that through modifying the parameter "msak" , it could achieve to get off the background color , I'd like to know if it could do this ?

An image in an icon file can have transparent pixels if its color depth is below 32 bpp. If the color depth is 32 bpp all the pixels can have different levels of transparency, called the alpha value. The alpha value can vary from 0 to 255. The lower the alpha value is the more transparent is the pixel. If the alpha value is 0, the pixel is invisible.

The Icon Editor in CVI is very limited and do not support these features for icon creation. This Application was created a long time ago before all these new formats were introduced and NI did'nt really upgrade this over the last 5 years or so.

There's a lot o tools available out there but I like this one: http://www.image2icon.com/  You can download a trail verison there.
