msstyleEditor version history
2.1.1.0 Dec 10, 2024
- automatically convert image resources between straight and premultiplied alpha (#108)
- imported images are assumed to be straight alpha (as per PNG specification), and thus converted to premul. alpha.
- exported images are assumed to be premultiplied alpha and thus converted to PNG standard conforming straight alpha.
- STREAM resources (DWMxxxxxx classes) are never converted, because they already come as straight alpha.
- added a readonly edit box to the control preview (#152)
2.0.1.0 Mar 22, 2024
- added support for animation properties (see "animations" class).
- added search options for FILENAME and FONT.
