TclTk binding for Blend2d has been released. Download blend2d-1.0a1
Within the package you can find a preliminary reference manual and a lot of demos.
QUICK START
How to create and view an image generated with blend2d ?
Let's create a very simple image with Blend2d
package require Blend2d
BL::Surface create mySfc
mySfc clear
mySfc fill [BL::circle {200 200} 50] -style [BL::color orange]
... you got the idea ...then we could:
- save it in a file (currently only .BMP is supported)
mySfc save "./image01.bmp"
- copy the image in a tk-photo
image create photo photo1
mySfc writeToTkphoto photo1... and then embed photo1 in a widget, or save it in a file ...
But we could also create a totally new kind of image that can be embedded in a widget and manipulated in real time...
You already know how to display a tk-photo in a widget like a canvas or a label. tclBlend2d provides a new type of image named "blend2d".
image create blend2d mySrf1
"mySrf1" is both a new image, and a BL::Surface object (i.e. a command). So, you can embed this image in a widget
label .a -image mySrf1
pack .aand then draw on "mySrf1" ...
mySrf1 clean
mySrf1 fill [BL::circle {100 100} 80] -style [BL::color red]
...`You can continue to draw in mySrf1, and istantly see the results in the label-widget.

TclTk binding for Blend2d is almost ready .. Just some fixing for the last Blend2d features (multithread rendering) and for a more tcl-ish API.
In the meantime you can play with the new pixmix 2.x demos. pixmix includes a preliminary tcl-Blend2d engine and, although Blend2d is a vector graphics engine, it provides amazing performances even for working with large (fullscreen) bitmaps.
