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.

If the first character of string isthe image label is read from a file titled by the remaining characters in the string. This option takes last image in the current image sequence and inserts it at the given index.

Quality was hardly degraded and file size is small. Specify the image source using an image index represented by ustarting at zero for the first image, eg: Encrypting flatteb being written is not supported.


If a visual is not specified, the visual class that can display the most simultaneous colors on the default screen is chosen. QuantumRange is the maximum integral value which may be stored in the red, green, or blue channels of the image.

What is your IM version? Note, these two command are equivalent: Similarly, if only fllatten height is specified e. The default is True. Gamma is an exponent that ranges from 0. By default, ImageMagick applies operations all channels, except the opacity channel, in an image. If the first character of string isthe image comment is read from a file titled by the remaining characters in the string.


The sequence of images is terminated by the appearance of any option.

Flatten transparency – ImageMagick

Many solutions were offered. Then the next layer image contains the object that casts that shadow.

For example, if you type the following command: The text gravity primitive only iamgemagick the placement of text and does not interact with the other primitives.

If the —average option appears after all of the input images, all images are averaged.

Negative indexes are relative to the end of the sequence, for example, -1 represents the last image of the sequence. Use —strip to remove all profiles. Use this option to affect the the color management operation of an image see —profile. You will need this information to recover the steganographic image e. However, if the image is x, it is rotated by degrees.

If only a single 0 is provided, auto-thresholding will be performed. As a side effect, fully-opaque colors of this value may also become transparent, depending on the format. Use the ‘[0]’ form of the filename to just select the pre-flattened version of the image. My program uses ImageMagick to convert a multipage tiff to pdf.



The direction you choose specifies where to position the text when annotating the image. A number of algorithms search for a target color. The width and height give the size of the image that remains after cropping, and x and y are offsets that give the location of the top left corner of the cropped image with respect to the original image.

Paths See Paths represent an outline of imagemaguck object which is defined in terms of moveto set a new current pointlineto draw a straight linecurveto draw a curve using a cubic Bezierarc elliptical or circular arc and closepath close the current shape by drawing a line to the last moveto elements.

Alternatively, you can think of each image in the sequence as Layers of a set of see-through overhead transparencies. To extract a profile, the —profile option is not used. For example, if you want to use quality 75 for the main image and quality 90 to compress the opacity data, use —quality Resize the image so that its rendered size remains the same as the original at the specified target resolution.
