It does work. For maps, etc, I get dramatically better quality in the final book by using "--imagerescale 0". That's one of the reasons I wanted to try out "opf2mobi", because in Mobi Creator there's no way to stop the image quality being degraded to get the image under 64k.

In MobiPerl/Util.pm, there's this: Code:
# pdurrant # do not resize large images if the filesize is OK, # even if pixel dimensions are large if ($filesize < $maxsize and ((not $rescale_large_images) || ($x <= $maxwidth and $y <= maxheight)) and $type ne "PNG" and (not defined $scale_factor or $scale_factor == 1.0)) { # No transformation has to be done, keep data as is ... } Code:
if (($filesize < $maxsize and ((not $rescale_large_images) || ($x <= $maxwidth and $y <= $maxheight)) and $type ne "PNG" and (not defined $scale_factor or $scale_factor == 1.0)) or (not $rescale_large_images)) { |

Jellby, you are right! Not that I'm taking sides...
In my modified html2mobi.pl file that I call from within PDFRead, I sort of disable the automatic Palm image quality reduction which "fits" images within its maxsize (60K) by upping the maxsize to say, triple, that i.e. 180k. Code:
- In MobiPerl/Util.pm, changed bold part: my $maxsize = 61000*3; |

This is strange. My memory says that I allowed larger images in term of number of bytes but the code as you point out seems to say something else. I remember being very unwilling allow it but thought I gave in... I might just add a new flag...

Your memory is correct; you allowed larger images NOT to be resized/rescaled with that flag, but never took care of the secondary .jpg quality reduction to "fit" the Palm maxsize resitriction. At least, this is how *I* remember it.

Curious. Why is it I wonder, in that case, that my maps, which are >64k in size, look so much better with "imagerescale=0" set? It really is a huge quality difference; text which is "blurry" with the default setting is clear and sharp with the flag set.

There are these maxima: Dimensions: 640x480 pixels, it can be disabled with "--imagerescale 0" Filesize: 61440 bytes, it cannot be disabled with a flag (yet). If you want to test, run mobi2html on the generated mobi, and you'll see whether the image files were modified or not. |

Since I have fixed some "bugs" I did a version 0.41 which is available at
https://dev.mobileread.com/trac/mobiperl/ Let me know if I broke something (I have not tested it so much...) Changes in 0.0.42

If someone could build Windows binaries I'd be grateful - I don't have PERL installed on my PC .
