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.

Computer screens are normally 72 or 96 dots per inch while printers typically support,or dots per inch.


Also, I’m new to this forum. However, if the image delay is 40 or 50, the delay it imagemagifk changed to Use this option to assign a specific comment to the image, when writing to an image format that supports comments. If only the width is specified, the width assumes the value and the height is chosen to maintain the aspect ratio of the image.

A pixel is defined as noise if and only if this pixel is a maximum or minimum within the pixel window. If the —filter option precedes the jmagemagick option, the image is resized with the specified filter. The source is multiplied by the destination and fllatten the destination. Stack Overflow works best with JavaScript enabled. The comment is not drawn on the image, but is embedded in the image datastream via a “Comment” tag or similar mechanism.

That is it will ‘fill out’ the canvas of the image with transparent pixels.

ImageMagick: Command-line Options

Images which suffer from severe contouring when reducing colors can be improved with this option. This option affects operations that use virtual pixels such as —blur—sharpen—waveetc.


The destination is replaced with the source when imagemagik source is lighter, otherwise it is left unchanged. Similarly, if only the height is specified e. It may be used to adjust the rendered size for desktop imagemagck purposes by adjusting the scale applied to the pixels. As nick said, the function Imagick:: Sign up using Email and Password. The only acceptable values are 8 or However, if the image is x or x, it is resized to x A number of algorithms search for a target color.

Painting with pure black or white produces a distinctly darker or lighter area, but does not result in pure black or white.

flaften This option is useful if the image is of a known gamma but not set as an image attribute e. The psd file has 6 layers and it looks like the flattened jpg image is showing imagemagock the last three. Negative indexes are relative to the end of the sequence, for example, -1 represents the last image of the sequence.

Post as a guest Name. Another way of appending images is by smushing.

The order imagemqgick the kernel is determined by the square root of the number of entries. The shape primitives are drawn in the color specified in the preceding —fill option.

Multiplies or screens the colors, dependent on the destination color. When writing to a MNG file, a —page option appearing ahead of the first image in the sequence with nonzero width and height defines the width and height values that are written in the MHDR chunk. This option is also used to place subimages when writing to a multi-image format that supports offsets, such as GIF89 and MNG.


-flatten option use in ImageMagick – Stack Overflow

The actual replacement now that flattenImages has been deprecated is: Use —fuzz to make —trim remove edges that are nearly the same color as the corner pixels.

PSD images generally contain both a flattened version of the image and all its layers. If the former, then my command above in my previous comment worked fine. By default, color reduction chooses an optimal set of colors that best represent the original image.

Is there a way to flatten a. 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. Otherwise, —page behaves much like —geometry e.

If they are not of the same width, any narrow images will be expanded to fit using the background color. For example, —swap 0,2 swaps the first and the third images in the current image sequence.

The source and destination are complemented and then multiplied and then replace the destination. Use a radius of 0 to have the method select a suitable radius.

You can set the primitive color, font, and font bounding box color with —fill—fontand —box respectively. Choose from these intents:
