I was looking in MagickCore::CompositeOperator but i didn’t find flatten operator. Something like backgorund i found, but how to do gray50?. That’s what “-flatten” does. It takes a sequence of images, composes them one at a time against the previous image(s), taking transparency into account. As nick said, the function Imagick::flattenImages() is deprecated. Replacing it by Imagick::mergeImageLayers(Imagick::LAYERMETHOD_FLATTEN) partially.

For example here we append a set of letter images together, side-by-side, to form a fancy word, in a similar way that individual ‘glyphs’ or letters of a ‘font’, are joined lfatten. Simply replace this call with Imagick:: Otherwise, it will be scaled to the given dimensions. Floodfill recolors any pixel that matches the color of the target pixel and is a neighbor, whereas filltoborder recolors any neighbor pixel that is not the border color.

A negative image index counts images from the end of the current image sequence, therefore u[-1] refers to the last image in the sequence.

-flatten option use in ImageMagick – Stack Overflow

You will have to do a search to see if you can flaten that. When converting an image from color to grayscale, convert the image to the gray colorspace before reducing the number of colors since doing so is most efficient.

The left side of the stereo pair is saved as the red channel of the output image. The direction you choose specifies where to position the text when annotating the image.

The x and y offsets flatgen not affected by the —gravity option. If the x is negative, the offset is measured leftward from the right edge of the screen to the right edge of the image being displayed. Resize the image so that its rendered size remains the same as the original at the specified target resolution. A -fill blue label: If placement with ” -gravity ” is need look at either the above multi-image composition methods, or the special Layers Composition method that can handle both positioning methods simultaneously.


This option is like —page but acts as an image operator rather than a setting.

For example, 3af33aaffand aaaaffff are all equivalent. Gamma less than 1. Consider the target pixel as that specified by your coordinate. PSD images generally contain both a flattened version of the image and all its layers. Painting with white produces no change.

Try using this instead: Selects the darker of the destination and source colors. Refer to quantize for a description of these values. Painting with white inverts the destination color. If the first character ikagemagick string isthe image comment is read from a file titled by the remaining characters in the string. If a clipping path is present, it will be applied to subsequent operations. Specify the width of the region to be removed from both sides of the image and the height of the regions to be removed from top and bottom.

The replace method recolors any pixel that matches the color of the target pixel. This was one of the simplest solutions, with the amount of overlap given in a single location.

The color is specified using the format described under the —fill option. When used with the mogrify utility, this option will convert any image to the image format you specify. This option compares each image with the next in a sequence and returns the maximum bounding region of any pixel differences it discovers. For X direction shears, x-degrees is measured relative to the Y axis, and similarly, for Y direction shears y-degrees is measured relative to the X axis. Use image to composite an image with another image.

Consequently this has no effect on the image sequence order.


Negative indexes are relative to the end of the sequence, imagdmagick example, -1 represents the last image of the sequence. For example using Coalesce on a single image, will do exact the same job as using Flatten with a ” -background ” color of ‘ None ‘ or ‘ Transparency ‘.


The image is convolved with a Gaussian operator of the given radius and standard deviation sigma. Only mid-range colors such as the various shades of grey. If imagemaick —deconstruct option appears after all of the input images, all images are deconstructed.

Can you post a link to your tif file? You can include the image rlatten, type, width, height, or other image attribute by embedding special format characters listed under the —format option. If the x and y offsets are present, a single image is generated, consisting of the pixels from the cropping region.

See —geometry for details the geometry specification. To extract a profile, the fltten option is not used. The quality value results in a request for non-lossy compression.

The default is quality is 75, which means nearly the best compression with adaptive filtering. The —gravity option is also used in concert with the —geometry option and other options that take geometry as a parameter, such as the —crop option. Quality was hardly degraded and file size is small.

Screening any color with black leaves the original color unchanged. It is not necessary to use —clip to activate the mask; —clip is implied by —mask. If value is missing for a definition, an empty-valued definition of a flag will be created with that name.

The default quality value 75 results in a request for Edit Report a Bug. Use this option imageemagick annotate an image with one or more graphic primitives. SkewX and SkewY skew them with respect to the origin of the main image or the region.

The —chop option removes entire rows and columns, and moves the remaining corner blocks leftward and upward to close the gaps.
