Blend2d Gallery
Blend2D is a high-performance 2D vector graphics engine. See https://blend2d.com
Here you can find some screenshots taken from the demo included in the TclTk porting Blend2d
ABU 27-Mar-2025 -- This page is no longer maintained.
The new updated and ever growing Gallery is available at
https://abu-irrational.github.io/tclBlend2d-Gallery
It contains screenshots of about 90 Blend2d demos.
The source code for ALL these demos is delivered as a separate zip tclBlend2d-Gallery-1.5
After installing the core package (see Blend2d), you can unzip the above Gallery under any directory and play ...
