Imager::LargeSamples(3pm) User Contributed Perl Documentation Imager::LargeSamples(3pm) NAME
Imager::LargeSamples - track/document large sample support SYNOPSIS
# make a large sample image my $im = Imager->new(..., bits => 16); # call some method my $result = $im->$method(...); # was the image modified at its full sample size DESCRIPTION
Imager has had in-memory support for large samples for years now, but many methods still don't work at the higher sample size when supplied with a large sample image. This document will track which methods support large samples and which don't, for future improvements. Support by method Method Support Notes ------ ------- ----- arc Partial [1] box Partial [2] circle Partial [1] convert Full copy Full crop Full difference Full filter Partial Depends on the filter. flip Full flood_fill Partial [1] getpixel Full getsamples Full getscanline Full map None masked Full matrix_transform Full paste Full polygon Partial [1] polyline None read Partial See L<File format large sample support> read_multi Partial See L<File format large sample support> rotate Full rubthrough Full scale Partial Some qtypes support large samples scaleX None scaleY None setpixel Full setscanline Full string Full Preserves large samples, but most font drivers generate 8 or fewer bits of levels of coverage. transform None transform2 None write Partial See L<File format large sample support> write_multi Partial See L<File format large sample support> [1] filling an area using the fill parameter works at the full depth of the image, using filled => 1 and color works at 8-bits/sample [2] box() will fill the area at the supplied color, but outline at 8-bits/sample.
