$ convert 18suh240765.tif -channel BG -fx 0 18suh240765_R.tifĬonvert: no decode delegate for this image format `18suh240765.tif'.Ĭonvert: missing an image filename `18suh240765_R.tif'. Are there any plans to restore support for TIFF to ImageMagick?Ĭopyright: Copyright (C) 1999-2007 ImageMagick Studio LLC ImageMagick is a powerful image viewer and editing tool that we can use within the Linux ecosystem. The default background in ImageMagick is white. Setting a transparent background did fix my problem. It can read and write over 200 image file formats, and can support a wide range of image manipulation operations, such as resizing, cropping, and color correction. I found this question when trying to solve a similar problem with the montage command, that would not preserve transparency. ImageMagick is a free and open-source software suite for displaying, converting, and editing raster image and vector image files. Says that ImageMagick deliberately removed the ability to read and write TIFF images from the official ImageMagick Mac OS X binary. none is one of the built-in color names for a fully transparent color. Identify: no decode delegate for this image format image.tif I see a message posted Wed 5:40 pm by Site Admin, under the heading I must use TIFF, because all of my images are GeoTIFF images, which are TIFF images that includes georeferencing info in the TIFF header record. PS: yes I know what sort of 'game' this was from.Indicates that the official ImageMagick for Mac OS X that I downloaded today can not read nor write any TIFF images. This topic from ImageMagick forum explains that there is no support for JPEG lossless operations in ImageMagick (whenever this changes, please post a comment with a link), and suggests using jpegtran (from libjpeg): jpegtran -copy none -progressive image.jpg > newimage.jpg jpegtran -copy none -progressive -outfile newimage. Do you have another image with the character overlaid on a known background image (say a image of the 'room' the anime character was in) and a image of that room (preferably as light as posible but with no black pixels in that background)īackgrounds just have to be as different as posible, and known. I have recovered transparency from anime images where the image was overlayed on two very different background images, and I had a copy of the original background images. Now if you have the same foreground image on a white background as well as the previously given black background the whole thing becomes easy!Īctually even a image overlayed on variable (but different) known backgrounds can be used. pdfjam offers other options, which may fit your needs. convert -channel R imageInRGB.tif imageOutR.tif. The command below copies from the input image the Red, Green, and Blue channels to the output image. Thus, I wrote a small script to rotate a JPEG image by 90°, keeping the EXIF header. exiftool keeps it, but its not very handy to use. The problem with jpegtran is that it does rotate the image, but it discards all the EXIF header data. pdfjam -paper a4paper -outfile myoutA4.pdf myout.pdf. I need to create an output image that contains ONLY the Red channel of the input image. This is an older question, however I found it whilst searching for a solution for this very task. but use pdfjam instead of ImageMagick to adjust the page size. You need different (and known' background colors) You can convert to pdf using ImageMagick. The only difference between these images is that the image was darkened uniformly, that does not add more information to determine the actual foreground color of a pixel when it has been anti-aliased by the background (get how 'transparent' each pixel is). image filename (note: becomes output filename for 'info:') k: CALCULATED: number of unique colors l: label meta-data property m: image file format (file magic) n: number of images in current image sequence, report once per frame o: output filename (used for delegates) p: index of image in current image list q: quantum depth (compile-time. One of the most common uses of ImageMagick is not to modify images at all, but only to magick an image from one image format to another.
