Eighth post of a series, translated from the "WinDev and PowerBASIC",
to explain the use of GDImage64 in
procedural* programming mode with Visual Studio 2022.
About Tutor_08This tutor introduces the use of multiple overlapping transparent layers, working in DWM composited mode.
The "aero_glass.png" used at the top of the z-order is displayed in "ZS_INACTIVE" mode,
that means it is disabled, however, all
WM_ messages are passed to the immediate underlaying sprites.
Even the layer shown at the bottom of the z-order is using variable opacity,
which makes it possible to discern the windows desktop in the background.
The fish animation is using 4 bitmaps, each bitmap being composed of multi frames.
See the
DetectMultiframe() function.
Last but not least,
the size of the standalone binary EXE is only
13 Kb.
*
procedural programming mode, is based on direct use of the FLAT API (Windows SDK) that is the core meat of the OS.
