pix - 2D graphics library

Tcl/Tk wrapper around Pixie, a full-featured 2D graphics library written in Nim.

Compatibility :

• Tcl/Tk 8.6 (Only tested with Tcl/Tk 8.6.14).

Platforms :

Source distributions and binary packages can be downloaded here.

Example :

# Init 'context' with size + color.
set ctx [pix::ctx::new {200 200} "white"]

# Style first rectangle.
pix::ctx::fillStyle $ctx "rgba(0, 0, 255, 0.5)" ; # blue
pix::ctx::fillRect $ctx {10 10} {100 100}

# Style second rectangle.
pix::ctx::fillStyle $ctx "rgba(255, 0, 0, 0.5)" ; # red
pix::ctx::fillRect $ctx {50 50} {100 100}

# Save context in a image file (*.png|*.bmp|*.qoi|*.ppm)
pix::ctx::writeFile $ctx rectangle.png

# Or display in label by example
set p [image create photo]
pix::drawSurface $ctx $p
label .l -image $p ; pack .l
