I tried ashkulz's win32 executable (v0.6) and obtained great results trying to convert the sample chap6.pdf into my readers native .imp format using PDFRead on the resulting .png in the out folder.
The optimal PDFRead settings used were:
1. In Format 'imgdir'
2. Out Format 'imp2' for EBW1150 or 'imp1' for REB1200. Just substitue your reader's format here instead.
3. Use a 'portrait-p' profile and 'portrait-full' layout mode
4. Check the 'no dilation' box (I tried dilation and since the pi .png's are in a lower resolution it looks terrible!)
5. Click 'Convert'
Looks promising, now only to get that pi algorithm incorporated into PDFRead (with GUI)!
