I will need to think about it.Įg: -geometry and -gravity locates the position on the background image, while -justification locates the point in the overlay image that is to be aligned with that location! (all will need to be integers, as only image distortions can do sub-pixel positioning of images). Provide any channel constant that is valid for your channel mode. The row offset of the composited image channel. In the past, the composite command was the combine command, so if you can't find the. Generating the thumbnail at the same time is left as an exercise for the reader. I know the background image dimensions ahead of time. The composite command allows you to overlay one image on another. I used the ever useful ImageMagick for the overlay. Id like to resize the overlay image on the fly so it matches the background, then merge them together. However, the overlay can be bigger or smaller than the background image. The column offset of the composited image y. I am using imagemagick to overlay one image over another with a blending option. Hmmm that may not be a bad idea as a way to implement justification, and now is the time for such ideas. Imagick object which holds the composite image compose. That will position the image using gravity, then the overlay image using justification relative to that position, BUT it will not position the image to a specific point! In IMv7 I have a 'justification' setting planned. Gravity Center (if given BEFORE the -composite operation that uses it), aligns the center of BOTH images. How can I do that I tried to composite right over the gif, like: composite -geometry +519+0 overlay.png my.gif test.gif But only put the png in the first frame. You will need to subtract the 'pin-point' location in that image to get it to pin point in the right location. Note the +50+50 is the location of the top-left corner of the 'tool_marker.png" image. What I mean is that you are expected to load an image prior to applying operators to it, rather than to build up a list of operators and then load an image and hope ImageMagick remembers what you said you wanted done if you ever loaded anything.Code: Select all convert background.jpg tool_marker.png -geometry +50+50 -composite result4.jpg See Command Line Processing for advice on how to structure your composite command or see below for example usages of the command. imagemagick image-manipulation Share Improve this question Follow edited at 22:24 asked at 22:04 user88036 Add a comment 1 Answer Sorted by: 12 composite -blend 30 1.jpg 2.jpg res.jpg will do the job. The order of parameters is also stricter, favouring: magick INPUT OUTPUT Sponsor Overlap One Image over Another Example Usage Option Summary Use the composite program to overlap one image over another. Note that at Version 7 of ImageMagick, the commands changed: Version 6 | Version 7 For example, given these two images: convert -size 352x288 -composite sydney.png jet2.png -geometry 64圆4+176+144 -depth 8 test.png convert -size 352x288 -composite sydney.png jet2.png -geometry 32x32+176+144 -depth 8 test.png. Or, if we want to also affect the grey(80), we can incorporate some fuzz: convert bean.jpg \( image2.png -fill "rgba(128,128,128,0.5)" -fuzz 20% -opaque gray \) -composite result.png First of all, overlay and background do not need to be the same size for composite to work. convert source.jpg \ \ ( mask.jpg -normalize +level 0,60 \) \ -compose screen -composite destination. This will generally give the mask the effects of 'dodging' or 'burning' which, compose Screen will respect. We can now make precisely mid-grey into semi-transparent mid-grey and overlay like this: convert bean.jpg \( image2.png -fill "rgba(128,128,128,0.5)" -opaque gray \) -composite result.png 1 Answer Sorted by: 6 Use the +level, or -level-color options to adjust the white/black points. Let's make an overlay (image2.png) first, with 3 progressively lighter shades of grey starting with 80/255 on the left, 128/255 in the middle and 200/255 on the right: convert -size 200x438 xc:"gray(80,80,80)" xc:gray xc:"gray(200,200,200)" +append image2.png
