![]() ![]() Otherwise, subdirectories can be used to segregate related images to minimize texture binds. ![]() If all images fit on a single page, no subdirectories should be used because with one page the app will only ever perform one texture bind. Images in the same directory go on the same set of pages. ![]() If the images in a directory don't fit on the max size of a single page, multiple pages will be used. For each directory of images TexturePacker encounters, it packs the images on to a larger texture, called a page. Given a directory, it recursively scans for image files. TexturePacker can pack all images for an application in one shot. Note that TexturePacker runs significantly faster with Java 1.7+, especially when packing hundreds of input images. TexturePacker can also be run from the standalone nightly, just substitute runnable-texturepacker.jar for gdx.jar extensions/gdx-tools/gdx-tools.jar in the above. Java -cp gdx.jar extensions/gdx-tools/gdx-tools.jar .texturepacker.TexturePacker inputDir Java -cp gdx.jar:extensions/gdx-tools/gdx-tools.jar .texturepacker.TexturePacker inputDir The TexturePacker class is in the gdx-tools project. It also uses brute force, packing with numerous heuristics at various sizes and then choosing the most efficient result. TexturePacker uses multiple packing algorithms but the most important is based on the maximal rectangles algorithm. It stores the locations of the smaller images so they are easily referenced by name in your application using the TextureAtlas class. libgdx has a TexturePacker class which is a command line application that packs many smaller images on to larger images. Binding the texture is relatively expensive, so it is ideal to store many smaller images on a larger image, bind the larger texture once, then draw portions of it many times. The API will resize your images and crop away the parts that are visually the least interesting.In OpenGL, a texture is bound, some drawing is done, another texture is bound, more drawing is done, etc. Take advantage of smart cropping to create thumbnails with different aspect ratios. Resizing includes correct gamma scaling, bicubic transparency edge correction and natural image sharpening. You only have to upload the original once and then generate the image sizes you need. The API can resize your images as well as optimising them. When doing this you may also set custom Cache-Control and Expires headers. You can instruct the API to save the optimized images directly in your Amazon S3 or Google Cloud Storage buckets. For PNG images the copyright information can be preserved. You can choose to preserve copyright information, the GPS location and the creation date in the compressed JPEG images. Convert images to WebP, JPEG or PNG (new)Ĭonvert your images to another format, or ask the API to give you the smallest image format! Images with a transparent background can be filled with a color you specify. ![]() You can either upload images directly or specify a URL to the image you want to compress. Upload directly or provide a URL to the image You only have to upload your source image and download the result. The API compresses WebP, JPEG and PNG images. curl -user api: YOUR_API_KEY \įeatures Same API for WebP, JPEG & PNG images The server will compress your image and respond with a URL where you can grab the result. You can also create your own integration with any HTTP(S) client. The community has also created a large number of third-party add-ons using the Developer API. You can also use the WordPress plugin to compress your JPEG and PNG images. Official client libraries are available for Ruby, PHP, Node.js, Python, Java and. Once you retrieve your key, you can immediately start shrinking images. Go straight to the reference and view the examples how to use the API in your own code. ![]()
