| meillo@6 | 8 |
| meillo@13 | 9 .B resize\-gd <width>x<height> PICTURES |
| meillo@6 | 10 |
| meillo@6 | 11 .SH DESCRIPTION |
| meillo@6 | 12 The program resizes given images to a specific size. The files are modified, so copy the files before if you want to keep the original pictures! |
| meillo@6 | 13 .PP |
| meillo@6 | 14 If <size> is given, aspect ratio of the images is preserved and only shrinking is done. Smaller images remain unmodified. |
| meillo@6 | 15 .PP |
| meillo@6 | 16 If <width>x<height> ist given, the images are resized to match that dimensions. The images probably get stretched and enlarged. |
| meillo@6 | 17 .PP |
| meillo@14 | 18 Only JPEG and PNG files are supported. The filetype is detected by the filename suffix which has to be `.jpg', `.jpeg' or `.png'. |
| meillo@6 | 19 Unsupported files get skipped. |
| meillo@6 | 20 .PP |
| meillo@6 | 21 This program is meant to be a small(er) alternative to the |
| meillo@13 | 22 .BR mogrify \-resize |
| meillo@13 | 23 command of ImageMagick. Mainly because ImageMagick has lots of dependencies, while the GD\-Library has less. |
