Windows Imaging Component Demo

Thought I'd see if my WIC demo worked in tB. Happy to report the initial import of the VB6 project worked flawlessly. From there I rewrote for 64bit. Thought it's worth noting how much easier WinDevLib API modules make this: Rather than go through and update all the Win API defs, all I did was comment them out, letting WinDevLib take over those in addition to taking over the COM interfaces from oleexp. After a minor hiccup (major bug in WinDevLib.IStream, now fixed), all that needed to be modified was removing some oleexp. qualifiers, switching GetObject to GetObjectW since the intrinsic version was getting priority, and changing handles/pointers to LongPtr.

Attached is the 64bit port, and a zip with the original VB6 project and unmodified tB import.

Update (Version 0.4, 06 Apr 2024): - Bug fixes to work with latest WDL versions (Issue #1). Fix save notification position.

Update (Version 0.3, 03 Mar 2024): Added BMP save option; also .twinproj has been updated to use a more recent version of WinDevLib (formerly tbShellLib) due to errors in the package tB did not raise at the time this project was released.

Original project page: [VB6] Intro to the Windows Imaging Component (WIC): Scale and convert JPG to PNG (the attached version adds BMP as a supported save format)

Errors in WICImage.cls (tB v494)

Was looking for improved PNG support in tB so downloaded your 64-bit version of WICDemo for a test run. Thanks for providing this!

When I opened your tB Project in tB v494, I see 4 errors. They are all similar to this one (whenever passing a 0& for WICRect type):

Thanks again,

Mike
