I asked yellowled about this (i thought it could be a 2k11-problem) and he told me it is because of wrong image-height of the portrait-format. Settings are on 200px height, but imagemagick resizes the thumbs sometimes to 199px because of the image-ratio. There seems to be rounding-differences within s9y to calculate the thumb-size/height/width.
To solve this problem, i included \! into the size-parameter of imagemagick as it is found on line 667 within /include/functions_images.inc.php
Code: Select all
$cmd = escapeshellcmd($serendipity['convert']) . ' -antialias -resize '. serendipity_escapeshellarg($newSize) .'\! '. serendipity_escapeshellarg($infile) .' '. serendipity_escapeshellarg($outfile);
...and now, floating is working good, as you can see here
