This port implements support for loading and using PNG images with
|
|
Tcl/Tk. Although other extensions such as Img also add support for PNG
|
|
images, I wanted something that was lightweight, did not depend on libpng,
|
|
and which would be suitable for inclusion in the Tk core, as Tk does not
|
|
currently support any image formats natively that take advantage of its
|
|
internal support for alpha blending, and alpha antialiasing and drop shadows
|
|
really go a long way toward beautifying Tk applications.
|
|
|
|
At this time, the package supports reading images from files or binary
|
|
data. Base64 decoding is supported as of version 0.6. Exporting images
|
|
to PNG format is not supported yet.
|
|
|
|
The package supports the full range of color types, channels and bit
|
|
depths from 1 bit black & white to 16 bit per channel full color
|
|
with alpha (64 bit RGBA) and interlacing. Ancillary "chunks" such
|
|
as gamma, color profile, and text fields are ignored, although they
|
|
are checked at a minimum for correct CRC.
