![]() ![]() Then you will have to use ffmpeg to reconstitute your video. Where you can change %03d.png to have any number other than 3 to set the number of leading zeros. Or convert video*.png null: overlay.png -gravity G -geometry +X+Y -layers composite new_video_%03d.png Final Composite Image (-resize 256x256 output. The location of the overlaid image (inner.png) is controlled by the -gravity and -geometry settings. Where G is the gravity setting such as center, X and Y are the desired offsets from the gravity setting. composite take the first image (circle.png) and overlays the second image (inner.png) according to the current -compose setting (which defaults to a value of Over). Then assuming all frames are the same size and numbered with leading zeros, convert video*.png null: overlay.png -gravity G -geometry +X+Y -layers composite new_video.mpeg I am not sure, but you may need to add -coalesce after the video.mpeg, if the frames are optimized in some way to change the frame sizes as in gif animations.Īlternately, suppose you convert all video frames to png. with -blend 100 result will be same as 1.jpg. I used your pictures and here is the result: If you want to make opacity of first image more or less, you shoud modify -blend param from 0 to 100 (with -blend 0 your 1.jpg will be transparent, so result will be same as original 2.jpg. The latter can be done in ImageMagick using -layers composite, assuming your ImageMagick has ffmpeg as a delegate library convert video.mpeg null: overlay.png -gravity G -geometry +X+Y -layers composite new_video.mpeg composite -blend 30 1.jpg 2.jpg res.jpg will do the job. Or the same one png (selectable) overlaying each frame of the video. Alternately, suppose you convert all video frames to png. Or one different png per every frame of the video. convert video.mpeg null: overlay.png -gravity G -geometry +X+Y -layers composite newvideo.mpeg I am not sure, but you may need to add -coalesce after the video.mpeg, if the frames are optimized in some way to change the frame sizes as in gif animations. Do you want all pngs overlaying each frame of the video. Using Imagemagick 6.9.10.9 Q16 Mac OSX, it would be: convert JN6W6.gif -coalesce -resize 600x400 null: PAiVp.png -gravity center -layers composite -layers optimize JN6W6PAiVp1. Unless otherwise noted, each option is recognized by the commands: convert and mogrify. With Imagemagick, you need to do a coalesce on the gif (to fill out the full frames) and -layers composite to combine the animated gif with a static image. 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. 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.Please clarify about the sequence of pngs. Below is list of command-line options recognized by the ImageMagick command-line tools. The order of parameters is also stricter, favouring: magick INPUT OUTPUT Note that at Version 7 of ImageMagick, the commands changed: Version 6 | Version 7 Supports many common formats (png, jpeg, tiff, pdf, etc) and manipulations (rotate, scale, crop, trim, flip, blur, etc). 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 Type Package Title Advanced Graphics and Image-Processing in R Version 2.7.4 Description Bindings to 'ImageMagick': the most comprehensive open-source image processing library available. 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 Using Imagemagick 6.9.10. 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 With Imagemagick, you need to do a coalesce on the gif (to fill out the full frames) and -layers composite to combine the animated gif with a static image. ![]()
