IMImage7MBS.RemoveZeroDelayLayers
Type Topic Plugin Version macOS Windows Linux Console & Web iOS
method ImageMagick7 MBS GraphicsMagick Plugin 20.0 Yes Yes Yes Yes No
Function: Removes any image that as a zero delay time.
Notes:
Such images generally represent intermediate or partial updates in GIF animations used for file optimization. They are not ment to be displayed to users of the animation. Viewable images in an animation should have a time delay of 3 or more centi-seconds (hundredths of a second).

However if all the frames have a zero time delay, then either the animation is as yet incomplete, or it is not a GIF animation. This a non-sensible situation, so no image will be removed and a 'Zero Time Animation' warning (exception) given.

No warning will be given if no image was removed because all images had an appropriate non-zero time delay set.

Due to the special requirements of GIF disposal handling, GIF animations should be coalesced first, before calling this function, though that is not a requirement.

See RemoveZeroDelayLayers function in ImageMagick documentation.

IMImage7MBS.SetImageColorMetric(other as IMImage7MBS) as Boolean
Type Topic Plugin Version macOS Windows Linux Console & Web iOS
method ImageMagick7 MBS GraphicsMagick Plugin 20.0 Yes Yes Yes Yes No
Function: Measures the difference between colors at each pixel location of two images.
Notes:
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.

See SetImageColorMetric function in ImageMagick documentation.

Notes:
You must make sure you have the right color space to make this work well with colorspaces.
Xojo on Mac uses Generic RGB, while Windows may use the colorspace of the display.

IMImage7MBS.Sharpen(radius as double, sigma as double) as IMImage7MBS
Type Topic Plugin Version macOS Windows Linux Console & Web iOS
method ImageMagick7 MBS GraphicsMagick Plugin 20.0 Yes Yes Yes Yes No
Function: Sharpens the image.
Notes:
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.
sigma: the standard deviation of the Laplacian, in pixels.

See SharpenImage function in ImageMagick documentation.

IMImage7MBS.Shave(rect as IMRectangleInfo7MBS) as IMImage7MBS
Type Topic Plugin Version macOS Windows Linux Console & Web iOS
method ImageMagick7 MBS GraphicsMagick Plugin 20.0 Yes Yes Yes Yes No
Function: Shaves pixels from the image edges.
Notes:
It allocates the memory necessary for the new Image structure and returns a pointer to the new image.

Shave returns a pointer to the shaved image. A null image is returned if there is a memory shortage or if the image width or height is zero.

rect: Specifies a RectangleInfo which defines the region of the image to crop.

IMImage7MBS.Shear(Xshear as double, Yshear as double) as IMImage7MBS
Type Topic Plugin Version macOS Windows Linux Console & Web iOS
method ImageMagick7 MBS GraphicsMagick Plugin 20.0 Yes Yes Yes Yes No
Function: Creates a new image that is an image copy of an existing one.
Notes:
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.
