chimgsize(1) - Linux man page

Name

chimgsize - Suggest width and height values for image resize operations

Synopsis

chimgsize [-w [widthmin:]widthmax] width height

chimgsize [-w [widthmin:]widthmax] image

Description

The program suggests width/height combinations to resize an image. The suggestions have the same aspect ratio as the original image. If a maximum width widthmax is specified -- and optionally a minimum width widthmin -- the program only suggests combinations for this range.

If no maximum width is specified the program suggests sizes for decreasing the image size.

Each suggestion is shown in one line containing classification, width and height.

The suggestions are classified as follows:

If the scale factor is not a natural number the first character in the line is ''-''.

If the scale factor is a natural number but not a power of 2 the first character in the line is ''+''.

If the scale factor is a power of 2 the first character in the line is ''*''.

Return Value

The program returns exit code 0 on success, a positive value on errors.
