1 .TH RESIZE\-GD 1 "resize\-gd\-0.2" "2008\-06\-15" "resize\-gd"
3 .SH NAME
4 resize\-gd \- resizes images using the gd library
6 .SH SYNOPSIS
7 .B resize\-gd <size> PICTURES
9 .B resize\-gd <width>x<height> PICTURES
11 .SH DESCRIPTION
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!
13 .PP
14 If <size> is given, aspect ratio of the images is preserved and only shrinking is done. Smaller images remain unmodified.
15 .PP
16 If <width>x<height> ist given, the images are resized to match that dimensions. The images probably get stretched and enlarged.
17 .PP
18 Only JPEG and PNG files are supported. The filetype is detected by the filename suffix which has to be `.jpg', `.jpeg' or `.png'.
19 Unsupported files get skipped.
20 .PP
21 This program is meant to be a small(er) alternative to the
22 .BR mogrify \-resize
23 command of ImageMagick. Mainly because ImageMagick has lots of dependencies, while the GD\-Library has less.
