Turns ' On' the alpha/matte channel, then copies the ' Off' the the image's transparency, so as to generateĪ gray-scale 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 The alpha channel turned on, it will have no effect.Įnables the alpha/matte channel and forces it to be fully opaque.Īctivates the alpha/matte channel and forces it to be fully Then it also resets the channel to opaque. Does not delete or change theĮxisting data, just turns off the use of that data.Īctivates the alpha/matte channel. Preserve existing (but specifically turned Off) transparencyĭisables the image's transparency channel. Should be used instead of this, unless you specifically need to typeĮnable the image's transparency channel. Choose the argument type from the list below. Used to set a flag on an image indicating whether or not to use existing alphaĬhannel data, to create an alpha channel, or to perform other operations on the alpha channel. alpha type Gives control of the alpha/matte channel of an image. If the matrix determinant has a sufficiently small absolute value it is rejected. The cumulative effect of a sequence of -affine transformations can be accomplished by instead by a single -affine operation using the matrix equal to the product of the matrices of the individual transformations.Īn attempt is made to detect near-singular transformation matrices. Rotate clockwise about the origin (the upper left-hand corner) by an angle a by lettingĬ = cos( a), s = sin( a), and using the following. Translation by a displacement ( t x, t y) is accomplished like so: See -transform, and the -distort method ' Affineprojection for more Respectively, is accomplished with the following. Scaling by the factors s x and s y in the x and y directions, Therefore,įour parameters suffice for rotation and scaling without translation. If the translation coefficients t x and t y are omitted they default to 0,0. 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. 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 $ convert 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. adjoin Join images into a single multi-image file.
