-adaptive-resize geometry, adaptively resize image with data dependent triangulation. -adaptive-sharpen geometry, adaptively sharpen pixels; increase effect. Due to recommendations for using adaptive-sharpen ( discourse-server =1&t=) I decided to give it a try. -adaptive-blur -adaptive-sharpen -black-threshold -clut (when mapping greyscale CLUT image to alpha channel if set by -channels) -colors for gray colorspace.

ImageMagick Sharpen Resized Images

This is very similar to -contrast-stretchand uses a ‘histogram bin’ to determine the shafpen of color values that needs to be stretched. If this setting is used, then the search will stop as soon as it finds a match whose metric is less than or equal to the value. A point primitive is specified by a single point in the pixel plane, that is, by an ordered pair of integer coordinates, xy. If -colors is also specified, the total unique colors in the image and color reduction error values are printed.

The command arguments has the form “module arg1 arg2 arg If the -stroke setting is none the defaultthen a polyline is identical to a polygon. Reduce the number of colors in an image to the colors used by this image. Blur with the given radius, standard deviation sigmaand angle. I am currently running 6. This means the canvas page size is set to exactly the same size you specified, the image offset set relative top left corner of the region cropped.



If the x and y offsets are omitted, a set of tiles of the specified geometry, covering the entire input image, is generated. Factor is floating point number. As such -insert -1 will result in no change to the image sequence. Offsets, if present in the geometry string, are ignored, and the -gravity option has no effect. Now even that does not work for me.

Specify the count and the image to duplicate by its index in the sequence. Specify the amount of colorization as a percentage. Thanks for this excellent Image Magick topic. If your image is gamma-corrected, you can remove the nonlinear gamma correction, apply the transform, then restore it like this:.

Segment an image by analyzing the histograms of imagemwgick color components and identifying units that are imagekagick with the fuzzy c-means technique. The synonyms Cos and Sin may also be used. This makes the bottom-left of the text becomes the upper-left corner of the image, which is probably undesirable.

If private is chosen, the image colors appear exactly as they are defined. The value used with Exp should be negative so as to produce a decaying exponential function.

You can extract the luminosity of an image by changing the images colorspace and separating the channels. A roundRectangle primitive takes the same corner points imagemgick a rectangle followed by the width and height of the rounded corners to be removed.


When used with the mogrify utility, this option converts any image to the image format you specify. Specify the image by its index in the sequence. The image x and y coordinates are the possible frequencies along the x and y directions, respectively, and the pixel intensity values are complex numbers that correspond to the sinusoidal wave amplitudes.

The weights should typically be fractions between -1 and 1.

This option sets the comment meta-data of an image read in after this option has been given. Use the -list option with a ‘ Mode ‘ argument for a list of -mode arguments available in your ImageMagick installation.

Command-line Options @ ImageMagick

To position the image, use offsets in the geometry specification or precede with a -gravity setting. If the first character of string isthe image label is read from a file titled by the remaining characters in the string.

By adding a exclamation character flag to the geometry argument, the cropped images virtual canvas page size and offset is set as if the geometry argument was a viewport or window. Finally, reset recolors all pixels.
