- GifRotat
- --------
-
- Program to rotate a gif image by an arbitrary angle.
-
-
- Usage:
- ------
-
- Usage: GifRotat -a Angle [-q] [-s Width Height] [-h] GifFile
-
- If no GifFile is given, GifRotat will try to read stdin for GIF file.
-
-
- Memory required:
- ----------------
-
- Screen (of source image).
-
-
- Options:
- --------
-
- 1. -a Angle : Specifies the angle to rotate in degrees with respect to
- the X (horizontal) axis.
- 2. [-q] : quite mode. Default off on MSDOS, on on unix. Controls printout
- of running scan lines. Use -q- to turn off.2
- 3. [-s Width Height] : Since rotated image will have the same image size as
- original, some parts of the image will by clipped out and lost. By
- specifing a (bigger) size explicitly using the '-s' option, these parts
- may be saved.
- 3. [-h] : print one command line help, similar to Usage above.
-
- Notes:
- ------
-
- Image is rotated around its center. No filtering is performed on the output
- which have identical color map as the input. This is mainly since filtering
- will require color quantization which is very memory/time intensive and
- out of MSDOS memory limits even for small images.
