Code: Select all
;Draw bitmap setting a transparent color
;Ref : [url]http://msdn.microsoft.com/library/en-us/shellcc/platform/commctls/imagelist/reflist.asp[/url]
;this example draws a 200x200 256 colors bitmap at 0,0 coord in the window
;black (0,0,0) is set as the transparent color
;change the includebinary with your own bitmap (200x200 256 color)
