RotateImage.exe, Version 1.02
Rotate a bitmap by a multiple of 90 degrees
Usage: ROTATEIMAGE image [ output ] [ options ]
Where: image input image file (bmp, gif, jpg, png or tif)
output output file name and type (default: image_rotateddeg,)
same type as input image)
Options: /M:size Maximum dimension of rotated image in pixels, either as
(original) width x (original) height (e.g. /M:1024x768)
or as a single number for the largest dimension (e.g.
/M:1024, equivalent to /M:1024x1024); if image does not
fit within the specified dimensions, it will be resized
while preserving its original aspect ratio
/R:deg Rotation in degrees (90, 180 or 270; default: 0)
Notes: Unless an output file name is specified, the rotated output file name
is the input image file name with "_rotated" and the amount of degrees
appended, e.g. image_rotated90.gif; if no output file is specified,
the file types of input and output file are identical.
Return code ("errorlevel") equals the width of the (resized) output
image before rotation, or -1 in case of errors
