A ruby ImageMagick library that doesn't suck

A ruby ImageMagick/GraphicsMagick library that doesn't suck

Very naive bindings for stb_image.h. Implements only stbi_set_flip_vertically_on_load and stb_load since these are the 2 functions I need to load an image as a texture in OpenGL. The reason I made this instead of using stb-image is because stb-image didn't implement stbi_set_flip_vertically_on_load, as far as I can tell, which is useful/necessary when wanting to load image data in a format immediately consumable by OpenGL (see Example in README).

Mainly the product of messing around, this gem comprises Ruby code for a few useful &quot;Amazon Hacks&quot; -- common techniques for manipulating Amazon product URLs and Images. This is mainly useful if you find yourself creating a site where you might link to Amazon product pages and display images for them. Examples of this might include: * Social consumption sites like {All Consuming}[http://www.allconsuming.net/] * Blogs or tumbleblogs with book/music/etc. reviews * Normalizing Amazon links or create associate IDs This GEM is NOT related to using the Amazon Web Services and there is already an excellent gem for that if you need more heavy-duty use of the Amazon website (this gem does not even communicate with Amazon at all). Also, note this gem is meant in the spirit of fun hackery. You can use it to create interesting images from Amazon on demand, but if you are going to use it on a serious website, please consider caching and attributing that image to Amazon (I also have no idea what the official legal policy for using Amazon's book images is). And of course, do not even consider using this for fraud. It is possible to generate &quot;20% off&quot; or &quot;Look Inside!&quot; badges on Amazon images, but this gem does not support that since I can not think of any reason why outside sites would use that. == FEATURES/PROBLEMS:

Image manipulation in JRuby with ImageScience compatible API

HexaPDF is a pure Ruby library with an accompanying application for working with PDF files. In short, it allows creating new PDF files, manipulating existing PDF files, merging multiple PDF files into one, extracting meta information, text, images and files from PDF files, securing PDF files by encrypting them and optimizing PDF files for smaller file size or other criteria. HexaPDF was designed with ease of use and performance in mind. It uses lazy loading and lazy computing when possible and tries to produce small PDF files by default.
