in reply to Batch conversion of images using gimp and Perl

Excellent perl script. Works like a charm and does a great job: jpeg file size went down without any noticeable quality degradation. One request though: Would it be possible to add an image re-size option please?

    You can find names of methods that correspond to various Gimp operations via Gimp's PDB Explorer (menu Xtns/PDB Explorer). In this case it is gimp_image_scale. According docs avialable via PDB Explorer this function expects following parameters:
    In: IMAGE image INT32 new_width INT32 new_height
    Perl module Gimp that provides bindings allows you to call this function as
    Gimp->gimp_image_scale($img, $new_width, $new_height);
    It also does some magick so you can call same operation under different names. All following calls do the same thing:
    Gimp->gimp_image_scale($img, $new_width, $new_height); Gimp->image_scale($img, $new_width, $new_height); $img->scale($new_width, $new_height);
    All you have to do is adding such call before saving jpeg file.

    You can learn more from documenation in Gimp module and from Gimp-Perl web site.

[Corion]: ambrus: AnyEvent(::HTTP) doesn't integrate well with Prima, that's my main problem
[Corion]: There is a weirdo shim because there is a POE integration for Prima, and if you use that, you can use the POE adapter of AnyEvent. What I'd want is something transport agnostic that parses HTTP or produces HTTP output, so that the communication with ...
[Corion]: ... the socket is done by my code. Ideally that module would not be based on callbacks ;)
