Hi I've found that paste method result broke when paste a source image which bottom source exceed 600px I've notice the same problem even with "height" param when top + height Show quoted text
> 600px
Think that tha same issue will affect even crop method.. but I couldn't test enought. I'm using fedora 4 with kernel 2.6.11 x86_64 and perl 5.8.6. Compiled jpegsrc.v6b jpeg library for jpeg support under Imager 0.50. I've tested only jpg files. Hope I could help Bye Mario

Please provide some sample code that reproduces the problem. I had a look through the code involved in Imager and don't see anything wrong at first look. Code that reproduces the problem will let me diagnose and fix it as soon as possible. Thanks. Tony

Hi! This is what I've found: use strict; use Imager; my $ImgFile1 = "./template/promemoria/messaggio.jpg"; my $img1 = Imager->new(); $img1->read(file=>$ImgFile1) or die $img1->errstr(); # This doesn't work ( well.. it result in a wrong pasting.. it seems that bottom (src_maxy) source img will set to max img height instead 610.. #$img1->paste(top=>544, # left=>72, # src_minx => 30,#30, # src_miny => 580,#715, # src_maxx => 120,#120, # src_maxy => 610,#728, # #height => 10, # #width => 90, # img=>$img1 # ); # This WORKS Imager::i_copyto($img1, $img1, 30, 715, 120, 728, 72,544 ); $img1->write(type=>"jpeg", file=>'mio.jpeg') or die $img1->errstr(); hope it can be usefull...

Ok, I think I see the problem now. The code is checking src_maxx instead of src_maxy when checking for bottom of image parameters. This means that: $im1->paste(src=>$im2, left => 20, right=>20, src_maxx => 20); or: $im1->paste(src=>$im2, left=>20, right=>20, src_maxy => 20); will produce unexpected results. In the first case because it sees src_maxx set and tries to use the undefined src_maxy, in the second case because src_maxy is ignored. If you change line 629 of Imager.pm from: if (defined $input{src_maxx}) { to: if (defined $input{src_maxy}) { and re-install that should fix the problem I see. If you get a chance please try this out to see if it fixes the problem for you. If it doesn't please let me know. I'll be doing a 0.51 release with this and 2 other fixes in the near future.

Just find another problem about it... in some cases bottom coords still exit wrong.. I've found this in the Imager.pm on line 649 ( I think you line is 4/5 line upper) $src_bottom > $r and $src_bottom = $b; And changed in: $src_bottom > $b and $src_bottom = $b; This seems to fix it.. Hope to be helpful.. Bye Mario
