#Imagemagick rotate plus#

This is a convenience for annotating an image with text. >-matte operation was the same as ' -alpha Note that while the obsolete +matte operation was the PNG, smaller as the RGB values of transparent pixels are more uniform,

This can make some image file formats, such as Set any fully-transparent pixel to the background color, while leaving That is the RGB color channels isĬomposite the image over the background color. ShapeĪs per 'Copy' but also colors the resulting shape mask with Grayscale intensity of the image, into the alpha channel, convertingĪ grayscale mask into a transparent shaped mask ready to be coloredĪppropriately. Turns 'On' the alpha/matte channel, then copies the 'Off' the image's transparency, so as to generateĪ grayscale mask of the image's shape. Same size as the original and with all its original RGB data stillĬopies the alpha channel values into all the color channels and turns This effectively creates a fully transparent image the OpaqueĮnables the alpha/matte channel and forces it to be fully opaque.Īctivates the alpha/matte channel and forces it to be fully The alpha channel turned on, it will have no effect. Then it also resets the channel to opaque. Disassociateĭisassociate the alpha channel from the image. Does not delete or change theĮxisting data, just turns off the use of that data. Deactivateĭisables the image's transparency channel. Preserve existing (but specifically turned Off) transparencyĪssociate the alpha channel with the image. Should be used instead of this, unless you specifically need to Matrix determinant has a sufficiently small absolute value it is rejected.Įnable the image's transparency channel. Transformations can be accomplished by instead by a single -affine operation using the matrix equal to the product of the matricesĪn attempt is made to detect near-singular transformation matrices. The cumulative effect of a sequence of -affine Rotate clockwise about the origin (the upper left-hand corner) by an angle Translation by a displacement ( t x, t y) is accomplished like so: -affine 1,0,0,1, t x, t y See -transform, and the -distort method ' Affineprojection for more Respectively, is accomplished with the following. Therefore,įour parameters suffice for rotation and scaling without translation. The transformation matrix complies with the left-handed pixel coordinateĪre rightward and downward, resp. Subsequently shift the image pixels so that those that are moved out of the The size of the resulting image is that of the smallest rectangle thatĬontains the transformed source image. Image are calculated using the following matrix equation. Internally, the transformation matrix has 3x3 elements, but three of themĪre omitted from the input because they are constant. The matrix entries are entered as comma-separated numeric values either in This option sets a transformation matrix, for use by subsequent -draw or -transform options. Set the drawing transformation matrix for combined rotating and scaling. a printf() integer format string (eg: '%d') is present in the output.the output image's file format does not allow multi-image files,.Save to multiple files, if any of the following conditions exist. In summary, ImageMagick tries to write all images to one file, but will morph), named: my00morph.jpg, my01morph.jpg,

Will create a sequence of 17 images (the two given plus 15 more created by As anĮxample, the command magick logo: rose: -morph 15 my%02dmorph.jpg Who have used the standard printf()' C-library function. Strings, such as ' %d' or ' %03d', are familiar to those Where the -scene number is placed in the filenames. Including a C-style integer format string in the output filename willĪutomagically enable +adjoin and are used to specify Separate files, whether or not the file format allows multiple images per file Use +adjoin to force each image to be written to More than one image needs to be written, the filename given is modified byĪdding a -scene number before the suffix, in order to ImageMagick is forced to write each image as a separate file. JPEG and PNG, do not support more than one image per file, and in that case An attempt is made to save all images ofĪn image sequence into the given output file. Join images into a single multi-image file.

Unless otherwise noted, each option is recognized by the commands: convert and mogrify. If you want a description of a particular option, click on the option name in the navigation bar above and you will go right to it. Below is list of command-line options recognized by the ImageMagick command-line tools.
