# gifrsize(1)

A program to resize image size by an integer factor, deleting bits when scaling down and duplicating bits when scaling up.

## NAME

gifrsize -  A program to resize image size by an integer factor, deleting bits when scaling down and duplicating bits when scaling up.

## USAGE

**gifrsize \[-q\] \[-S X Y\] \[-s Scale\] \[-x XScale\] \[-y YScale\] \[-h\] gif-file**

If no gif-file is given, GifRSize will try to read a GIF file from stdin.

## MEMORY REQUIRED

Line.

## OPTIONS

- \[-q\]

   Quiet mode.  Defaults off on MSDOS, on under UNIX.  Controls printout of running scan lines.  Use -q- to invert.

- \[-S X Y\]

   specifies the exact screen dimension of the output GIF.

- \[-s Scale\]

   Set scaling factor for both x & y direction to Scale. Default is 0.5. Note this is a floating point number.

- \[-x XScale\]

   Set scaling factor for x direction to Scale.  Default is 0.5. Note: this is a floating point number.

- \[-y YScale\]

   Set scaling factor for y direction to Scale. Default is 0.5. Note: this is a floating point number.

- \[-h\]

   Print one line of command line help, similar to Usage above.
