Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
method	ImageMagick7	MBS GraphicsMagick Plugin	20.0	✅ Yes	✅ Yes	✅ Yes	✅ Yes	All

Measures the difference between colors at each pixel location of two images.

A value other than 0 means the colors match exactly. Otherwise an error measure is computed by summing over all pixels in an image the distance squared in RGB space between each image pixel and its corresponding pixel in the reconstruct image. The error measure is assigned to these image members:

• mean_error_per_pixel: The mean error for any single pixel in the image.
• normalized_mean_error: The normalized mean quantization error for any single pixel in the image. This distance measure is normalized to a range between 0 and 1. It is independent of the range of red, green, and blue values in the image.
• normalized_maximum_error: The normalized maximum quantization error for any single pixel in the image. This distance measure is normalized to a range between 0 and 1. It is independent of the range of red, green, and blue values in your image.

A small normalized mean square error, accessed as image->normalized_mean_error, suggests the images are very similar in spatial layout and color.

IMImage7MBS.Sharpen(radius as double, sigma as double) as IMImage7MBS

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
method	ImageMagick7	MBS GraphicsMagick Plugin	20.0	✅ Yes	✅ Yes	✅ Yes	✅ Yes	All

Sharpens the image.

We convolve the image with a Gaussian operator of the given radius and standard deviation (sigma). For reasonable results, radius should be larger than sigma. Use a radius of 0 and Sharpen selects a suitable radius for you.

Using a separable kernel would be faster, but the negative weights cancel out on the corners of the kernel producing often undesirable ringing in the filtered result; this can be avoided by using a 2D gaussian shaped image sharpening kernel instead.

radius: the radius of the Gaussian, in pixels, not counting the center pixel.

method	ImageMagick7	MBS GraphicsMagick Plugin	20.0	✅ Yes	✅ Yes	✅ Yes	✅ Yes	All

Creates a new image that is an image copy of an existing one.

Shearing slides one edge of an image along the X or Y axis, creating a parallelogram. An X direction shear slides an edge along the X axis, while a Y direction shear slides an edge along the Y axis. The amount of the shear is controlled by a shear angle. For X direction shears, Xshear is measured relative to the Y axis, and similarly, for Y direction shears Yshear is measured relative to the X axis. Empty triangles left over from shearing the image are filled with the background color defined by member 'backgroundColor' of the image.. Shear() allocates the memory necessary for the new Image structure and returns a pointer to the new image.

See ShearImage function in ImageMagick documentation.

Empty triangles left over from shearing the image are filled with the background color defined by member 'background_color' of the image. ShearRotateImage allocates the memory necessary for the new Image structure and returns a pointer to the new image.
