How to rotate an image by an arbitrary angle?
The XShearImage() and YShearImage() methods are based on the paper “A Fast Algorithm for General Raster Rotation” by Alan W. Paeth, Graphics Interface ’86 (Vancouver). ShearRotateImage() is adapted from a similar method based on the Paeth paper written by Michael Halle of the Spatial Imaging Group, MIT Media Lab.
Is there a way to rotate an image without changing its size?
When an image is rotated by convert -rotate command the image size is enlarged. Is there a way to rotate around the center and to keep the image size, cropping the edges?
How to adaptively sharpen pixels in ImageMagick?
Adaptively sharpen pixels, with increasing effect near edges. A Gaussian operator of the given radius and standard deviation ( sigma) is used. If sigma is not given it defaults to 1. Join images into a single multi-image file. This option is enabled by default.
