==============

A few days ago, I asked a question about using .PNG Images in a Ruby/Tk
environnement, but I forgot to give some data.

  • What I have: WinXP Home SP1, Ruby 1.8.0, Tk8.3, no compiler.

  • What I’d like to do: to use a “.PNG” TkPhotoImage to show it as
    TkcImage in a TkCanvas.

I’m playing with 640x640 pictures (256 colors), for whitch the sizes
are about:
.BMP (windows) -> 410 Kb
.PNG -> 120 Kb
.PPM -> 1200 Kb
I have to use hundreds of them…

Somebody suggested me to use “GD”, whitch is a good tool for using
…PNG/.JPG but from whitch I cannot build any TkPhotoImage(s), or whitch
I don’t know how to use in TkCanvas.

Did someone try to do that?
Thank you.

Eureka!
I store files in .png format, and I transform in .ppm format just
before use… No other way :frowning:
