OK. My reader arrived today and just in time too because my litle tool is ready for my needs (still some bugs, and need to add more control, but it produces nice images and PDFs)
I've revisioned my tool a bit.
The way images are processed are different.
It won't convert the images anymore to gif.
Instead it will try to trim the image (remove borders) as good as it can (using imagemagick's trim function with fuzz for the techies here).
Colours will be changed to grayscale.
Then it will throw some anti-alias and filtering.
And finally resized to a max height of 754.
All the images will be made into a PDF. (one chapter per folder/zip)
Centered, without margins.
The chapters will be shown in the TOC
And that's where my tool end.
I'll use rasterfarian to convert the PDF to LRF. The newest version of rasterfarian uses netbpm, so that's more suitable for teh decoloring and edge enhancing.
And the end result are these files.
I like the TOC
(I'm now trying to test out the size limit. A file with 1600 images as pages is not loved by the reader....)
