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.

The text gravity primitive only affects the placement of text and does flatren interact with the other primitives. Empty triangles left over from rotating the image are filled with the color defined as background. If the image is enlarged, unfilled areas are set to black. By default, the image gravity is NorthWest. Choose from these filters:.
This method is reported to retain the image quality. Flatteb point method changes the matte value of the target pixel.
Specify the image by its index in the sequence. For more precise control over your text annotations, use —draw.
As on IM v6. The default ticks-per-second is The same color image displayed on two different workstations may look different due to differences in the display monitor. The size of the resulting image is set so that the rotated and scaled source image is exactly contained within the new image area.
In addition to width and height, use —size with an offset to skip any header information in imagemaguck image or tell the number of colors in a MAP image file, e. It can be either NoneAllTraceor a comma-separated list consisting of one or more of the following domains: The image read from the file is used as a clipping mask.
Set iterations to zero to repeat the animation an infinite number of times, otherwise the animation repeats itself up imagemagixk iterations times. Absolute, Perceptual, Relative, Saturation. Only when all the image layers have been created do you FlattenMosaicor Merge all the Layered Images into a single final image. Alternatively, you can choose a particular set of colors from an image file with this option.
Layering — IM v6 Examples
The events parameter specifies which events are to be logged. You can optionally control the stroke with the —stroke and —strokewidth options. The shape primitives are drawn flattten the color specified in the preceding —fill option.
Each miagemagick N in the sequence after Image 0 is replaced with the image created by flattening images 0 through N. The —channel setting can be used to specify the output channel of the result. For example, if you specify tiff as the format type and the input image filename is image.
The sequence of images is replaced by a single image created by composing each image after the first over the first image. If it is equal to 0. The Transparent color space behaves uniquely in that it preserves the matte channel of the image if it exists.
This allows you to work imagsmagick the same image over and over, as shown above, without problems. Use Ellipse to draw a partial ellipse centered at the given point with the x-axis and y-axis radius and start and end of arc in degrees e. After testing multiple settings I have discovered that if I remove the -density or lower it to -density 50 the pages which gave me problems are created unfortunatly the quality is very low and jagged. So none of these methods are satisfying.
Append an exclamation point to the geometry to force the image size to exactly the size you specify.
ImageMagick: Command-line Options
The source is multiplied by the destination and replaces the destination. As you can see the image processing for the above was simpler and cleaner than you normally would see with shadow generation, just by underlaying each image in sequence with a transparent starting canvas.
Refer to the color reduction algorithm for more details. The color of the backdrop is specified as the background color. Pixels within the shape are opaque, while pixels outside the shape are transparent. An X direction shear slides an edge along the X axis, while a Y direction shear slides an edge along the Y axis.
This option is also used to place subimages when writing to a multi-image format that supports offsets, such as GIF89 and MNG. The degree of lightening or darkening is proportional to the difference between the source color and 0.
