Image handling and transformation from Tcl (Tk not required). Part of the eTcl distribution for Win32, Linux and Windows Mobile (aka PocketPC). Will be soon available as stub-enabled extension for Win32 and Linux/x86.

RS 2006-02-03 - Example code: display an image file (JPEG or others, what Tk itself has not built-in) in the eTcl console:
#-- Convert a "pixane" image to a Tk photo
proc piximg file {
package req pixane
set p [pixane create]
pixane load $p -file $file
K [pixcopy $p] [pixane delete $p]
}#-- Export procs to the console interpreter (see corp and K for details)
console eval [corp piximg] console eval [corp K]
#-- The viewer now is similar to see described on console page:
proc see2 file {
set im [console eval [list piximg $file]]
console eval [list .console image create end -image $im]
}RS has tested that pixane 0.3 as came with eTcl 1.0pl6, on PocketPC, works well with the following formats: GIF, PNG (most), JPEG, BMP (uncompressed). So for my purposes, it is quite a good substitute for the Img package, which isn't yet available on PocketPC.
