Use > to change the dimensions of the image only if its size exceeds the geometry specification. < resizes the image only if its dimensions is less than the geometry specification. For example, if you specify 640x480> and the image size is 512x512, the image size does not change. However, if the image is 1024x1024, it is resized to 640x480.

Options are processed in command line order. Any option you specify on the command line remains in effect until it is explicitly changed by specifying the option again with a different effect.
file specifies the image filename. If file is omitted, it defaults to magick.miff. The default image format is MIFF. To specify a particular image format, precede the filename with an image format name and a colon (i.e. gif:image) or specify the image type as the filename suffix (i.e. image.jpg). See Image Formats Supported by ImageMagick for a list of valid image formats.
Specify file as - for standard output. If file has the extension .Z or .gz, the file size is com pressed using with compress or gzip respectively. Precede t he image file name | to pipe to a system command. If file already exists, you will be prompted as to whether it should be overwritten.
