Description DjVu was initially developed by AT&T and is used as an image compression technology that is an open sourced alternative to PDF. It allows for scanned documents, photographs and very high resolution images to be distributed via the internet. There are a whole host of DjVu viewers, browser plugins, encoders and decoders available on both Mac and Windows.

Technical Details DjVu was initially developed by Yann LeCun, L�on Bottou, Patrick Haffner, and Paul G. Howard at AT&T Labs from 1996 to 2001. It promises smaller files sizes than standard PDF's and is therefore perceived to be superior to PDF's primarily due to it's higher compression ratio. DjVu files are typically seperated into three images - the background and foreground (around 100 dpi) and the mask image which is higher resolution (e.g. 300 dpi). The background and foreground images are compressed using an algorithm named IW44 with the mask image compressed using JB2. Ultimately this results in dramatically reduced file sizes.

Category Image File
Description PNG pronounced ping is a format for storing bitmapped (raster) images on computers. It was created originally to replace the GIF file format when it was announced that the companies who created the GIF format wanted royalties. PNG uses indexed colors and lossless compression (like a .GIF file), but without those copyright limitations; it cannot be animated like a GIF image.

Technical Details PNG images are in many ways better than .GIF as they also include an 8-bit transparency channel, which allows the colors in the image to fade from opaque to transparent; GIF images only support fully opaque or fully transparent pixels. PNG supports palettes of 24-bit RGB colors, RGB images or greyscale or RGB images. PNG was intended to be able to transfer images on the Internet, not professional graphics, and so does not support other colour spaces (such as CMYK).
