Through the use of QT4 comes in a flirty dress with a lot of graphic effects to transition between different windows. It has an online tutorial to introduce the use of the program. $ metapixel -metapixel input.jpg output.png -l destinationfolder -s 10 -d 500įotowall is a composer of wallpapers, you can “mix” together several photos and apply effects, the work once done is rendered to create the final image. Install metapixel from your repository (available in Ubuntu) It’s an open source product, and even if a little dated (2006) plays its role perfectly.Metapixel is a command-line program and thus scriptable.Small percentages yield noticable improvements but are innocent enough so as not to be noticed without close inspection. Metapixel has a cheat option which overlays the photomosaic with the original image using a user-specified percentage.Alternatively, Metapixel can be instructed to honor a minimum distance between two occurrences of the same image in classical photomosaics. Metapixel can generate classical mosaics which contain at most one copy of each constituent image.Most of this time is spent loading and saving images. It takes about 75 seconds to generate a classical photomosaic for a 2048×2432 image with constituent images of size 64×64 and a database of slightly more than 11000 images on my not-so-fast Alpha. The matching algorithms match not only color but also form.Metapixel generates not only classical mosaics but also collage-style photomosaics (see examples).It prepares your source images so that they can be used by metapixel to create the actual photomosaic. metapixel-prepare is a utility that needs to be run before metapixel can be used. not aligned to a matrix) are substituted by matching images. It can generate classical photomosaics, in which the source image is viewed as a matrix of equally sized rectangles for each of which a matching image is substitued, as well as collage-style photomosaics, in which rectangular parts of the source image at arbitrary positions (i.e. Metapixel is a program for generating photomosaics. Shape collage is wrote in java, so it’s available for Linux, Mac and Windows, you can download the free version directly from the site or buy the version for personal use at $ 25Ĭheck some great collage on their Flickr page * generates super high-resolution images (up to 200 megapixels) Shape Collage has the following features: Vincent then realized that his algorithm wasn’t restricted to just boring rectangular collages like everyone else, and so, Shape Collage was born! He begin tinkering around and invented a new algorithm for automatically arranging photos in a collage. They required too much work to make a collage, they didn’t look nice, and they didn’t give you enough control. He thought about making a photo collage with his photos, but didn’t like the existing collage making programs. Shape Collage was started by Vincent Cheung in 2007 because he had thousands of photos and didn’t know what to do with them. Once again, Linux does not disappoint, and today I want to present three projects to create photo collages. Sure there are Gimp and Picasa that among the many features that give even offer these options, but there are other programs, perhaps smaller and simpler to just make this work? It happens every now and then you have a set of photos and you want to do with them a background image with a collage of them, or perhaps a mosaic, it’s possible in Linux?
