| vlt | Hello. I used `gs ... -sDEVICE=pdfwrite -c '[/CropBox [...]' -c ' /PAGES pdfmark' -f input.pdf` to crop a PDF file. It kind of works. It produces an output PDF of roughly the same size as the input but opened in a PDF viewer displays only the cropped area. But ... | 13:42.31 |
| | ... using that cropped file as input for `... -sDEVICE=png16m` ignores the cropping and I get a full size raster image. | 13:43.31 |
| | Is there a way to tell gs only to render a certain box of an input file when using one of the raster image output devices? | 13:44.31 |
| | My current workaround is to use -sDEVICE=ppm and pipe that to pnmcut. That is a lot of wasted calculations (though surprisingly low on memory consumption). | 13:46.33 |

| vlt | kens: Thank you! I’ll try that. | 14:21.06 |
| | Seems to work fine :) | 14:40.27 |
| | Is there an output device other than "pngalpha" that will also do this "anti-aliasing" on vector edges but doesn't try to compress that much? I tried ppm, tiff24nc and even (the compressing) png16m and got stair-steps. Any idea? | 14:48.31 |
| kens | Al the contone devices support -dGraphicsAlphaBits and -dTextAlphaBits | 15:15.20 |
| | Also there is tiffscaled which does anti-aliasing a different way | 15:15.45 |
| vlt | kens: Thanks! | 15:30.05 |
