Description

AnimGif.dll is NSIS plug-in, displaying animated banner on the installer page. Based on the Juan Soulie code. Unfortunately, the base program fails on some images (very seldom): in this case, you can use AnimGifPe.zip variant based on the Oleg Bykov' PictureEx sample, which also supports static BMP and JPEG, but unpacks image very slowly. Plug-in not stops installer execution when banner is displayed. Banner is not clickable. May be used in the page custom show/leave functions and on other (not page) windows with possible transparency limitations.

Command line (NSIS script)

/BGCOL

Color value may be hex (starting with 0x) and decimal (first is not 0). Hex value will be used as RGB color, decimal - as Windows system color index in GetSysColor() API call, see MSDN. If value not specified and target window stays hidden (for example in custom 'Show' function), default COLOR_BTNFACE will be used.
