![]() ![]() With the -gravity option you can change the origin, for example: If you want to place the image in the center, in one of the corners, or in the middle of one of the sides, then instead of specifying an offset, you can use the -gravity option. Please note that the overlay image will have a width of 400 pixels, and the height will be adjusted automatically to maintain the original proportions of the image, see the Image Geometry section for details. Magick IMAGE.jpg IMAGE1.jpg -geometry 400x300+50+10 -composite test27.jpg In the following example, IMAGE.jpg will be overlaid with IMAGE1.jpg, whose width will be 400 pixels, this image will be shifted from the left edge by 50 pixels and from the top by 10 pixels, the new image will be saved to the test27.jpg file: This item can be repeated many times to overlay several images on one. Geometry options, as well as the “ -composite” option. The name of the second image to overlay the first. The name of the initial image that will act as the background. The command to overlay one image on another consists of three main parts: Let’s consider how to overlay an image on an image and merge images. For details on installing ImageMagick, including which dependencies need to be installed to support the maximum number of formats, as well as a description of the command structure, examples of usage and all options, see the article: ImageMagick guide: installing, using, and troubleshooting. but then I have the right to rant, with the various experiences I have had.The “ magick” utility is part of the ImageMagick package. This takes administion work, but it is what makes a good GIF animation site. It is also better to have one representative animation for set of animations, rather than a pages of slightly different colored animations, if creating a library of animations. People should not have to wade though CRAP to find the gem they are seeking. A lot of GIF animation web sites have tens of thousands of GIF animations, 90% of which is CRAP. Both gifsicle and intergif have crapped out on me for some specific types of animation.ĪSIDE: Don't keep crap animations. make sure however that the non-IM optimizer did not destroy the final animated form. ![]() Im is pretty good, but sometimes it is better to optimize the animation using multiple methods and programs to see what is best. Even if they get by the banner and the watermark, the animation will not be a good as what a paying user could get.Īnd lastly, watch your GIF optimizaer. The best method has been to create a smaller, non-transparent version with a see-though water mark over the animation, as well as have the clearly visible banner underneath. Third, adding a banner under an animation will not protect the image. Second watch the number of added colors, GIF is not known for having a lot of colors and adding extra colors like white, can cause speckling problems. If the animation has no transparency, DON'T ADD TRANSPARENCY, figure out if you should use a specific color background as appropriate. You may however need to consider as few points. Of course if you are only doing this for one or a dozen animations (I doubt this) you can just tweek things until you are happy with the result. You need to really understand the GIF format, its limitations, handling, disposal, and optimization issues, if you are going to get good results for any GIF animation. You will be proud of yourself when you succeed.īasically you are asking for trouble and I would study completely all four IM Examples pages on animation and video handling before proceeding. Sorry, I can't give out that actual script But then I could not make some serious improvements for it too.Įssentially it did the task by coalescing, creating that extra space, drawing the watermark and re-optimizing the image. This script predated the '-layers' method too. I actually did work for a web site (they actually payed me money) to write a script that does exactly what you were requesting. Draw is one way, but another is to use "-layers composite" ![]()
