The package contains prebuilt binaries for Win-x64 and Linux-x64 (still troubles with MacOS ...).

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 .a
======
and 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.

TclTk binding is still at alpha stage, performances are amazing.
