meillo@6 3 .SH NAME
meillo@6 4 resize-gd \- resizes images using the gd library
meillo@6 5
meillo@6 6 .SH SYNOPSIS
meillo@6 7 .B resize-gd <size> PICTURES
meillo@6 8
meillo@6 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@6 18 Only JPEG and PNG files are supported. The filetype is detected by the filename suffix which has to be either `.jpg' or `.png' (in lowercase letters).
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@6 22 .BR mogrify -resize
meillo@6 23 command of ImageMagick. Mainly because ImageMagick has lots of dependencies, while the GD-Library has less.
