But before the analysis of the image must also determine the type of bmp-file. It's you and trying to do? It is a pity that in Alaska there is no standard read command parameters pixel downloaded image file.

i have read what Roger wrote but you need a Bitmap (File) for it

i´m try to "read" DWM ( Desktop Window Manager ) Color when change "Theme" to assign same Color to my Ownerdraw Part. this work with Codejock SkinFramework but i have Problem in "pure" Xbase++ while i can not convert Hue/Sat of 32bit AARRBBGG to Xbase++ Color.

First step is to parse AARRGGBB. Then take the resulting RGB and convert to HSV. The pure Hue plus Saturation at full brightness is the base color. Now overlay Value as a grayscale at Alpha over top of pure Hue and Saturation to get the Aero color. Then overlay that color over the frame color: rgb(235, 235, 235) at Intensity to get the final Composite Aero color result.
