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.

ImageMagick: Command-line Options

The default ticks-per-second is If the mask image contains an alpha channel, the opacity of each pixel is used to define the mask. If a visual is not specified, the visual class that can display the most simultaneous colors on the default screen is chosen. Darkens or lightens the colors, dependent on the source color value.

Partition is like plane except the different planes are saved to individual files e. Similarly, negative y is measured between the bottom edges.

By default the limits are files, MB memory, MB map, and unlimited disk, but these are adjusted at startup time on platforms that can provide information about available resources. The pixels are processed one at a time, but a different pixel of a image can be specified with a pixel index represented by p.


PSD images generally contain both a flattened version of the image and all its layers. However, if the filename extension matches a supported format, the extension imaggemagick replaced with the image format type specified with —format.

The offset is a distance in sample space from the mean, as an absolute integer ranging from 0 to the maximum sample value or as a percentage. The default is to use the estimate quality imaagemagick your input image otherwise This non-linear equation is intended to loosely approximate the quality provided by the JPEG v1 format. The —clip feature requires the XML library. The flattened image is blurry. The same color image displayed on two different workstations may look different due to differences in the imaegmagick monitor.

Appending Images Appending is probably the simplest, of the multi-image operations provided to handle multiple images. See “Image Segmentation” for details. Width and height give the number of columns and rows to remove, and x and y are offsets that give the location of the leftmost column and topmost row to remove.

Flattening images by default uses the background color ‘white’. By default, the displacement applies in both the horizontal and vertical directions. Append an exclamation point to the geometry to force the page size to exactly the size you specify.

When creating a montage, by default the label associated with an image is displayed with the corresponding tile in the montage. When writing a GIF89 file, only the bounding box method is used to determine its dimensions. The Mitchell filter flattten used if the image supports a palette, supports a matte channel, or is being enlarged, otherwise the Lanczos filter is used. The kernel is specified as a comma-separated list of integers, ordered left-to right, starting with the top row.

A negative y offset rolls the image top-to-bottom.

That is you can have a sequence of images or ‘layers’ that each adds one more piece to a much clatten complex image. As a side effect, fully-opaque colors of this value may also become transparent, depending on the format. X-rotate and y-rotate give the angle of the text and x and y are offsets that give the location imatemagick the text relative to the upper left corner of the image.


Glad it solved your Q. In this way, you can obtain pieces of other windows that overlap the specified window, and more importantly, you can capture menus or other popups that are independent windows but appear over the specified window.

Since the transformation usually changes imagemagickk image size, the origin of the transformation is the image center, not the upper left edge.

It is not necessary to use —clip to activate the mask; —clip is implied by —mask. If the former, then my command above in my previous comment worked fine. You imagemagickk optionally control the stroke with the —stroke and —strokewidth options. Strangely the exact same handling can be used to ‘clip’ or Crop an image to a virtual canvas that is smaller than the original image.

The quality value results in a request for non-lossy compression.


Email Required, but never shown. Each image pixel is represented by red, green, and blue levels which are equal for a gray pixel.

Darkens the destination color to reflect the source color. Merges a sequence of images. The —colors or —monochrome option, or saving to a file format which requires color reduction, is required for this option to take effect. ImageMagick examples mostly using php Imagick examples.
