Acrobat Flate Compression
Acrobat uses a flate compression tool for PDF files. This program allows PDF files to have their object streams individually compressed. Flate is an improvement of LZW compression. It is both more efficient and royalty free. Being able to read huge PDF files in plain test is very useful. It is great for feature extraction, program analysis, and new software design. The flate compression operation is found in the PDF Reference Manual and the PostScript Reference Manual from Adobe Systems. Flate works well on images with large areas of single colors or repeating patterns. An advantage of flate compression is that it is lossless. It does not remove data to reduce file size. You do not lose any important information, but you will gain back valuable space.
Flate Compression Filters
Flate compression filters looks at incoming requests. If the Accept-Encoding headers contains gzip or deflate then compression of files is activated. At the point, the server prepares the response. Once this happens, the filter looks at response, especially when it comes to content-type. Once compressed, the file is sent to the browser. These filters are made to work in default mode. No registry settings are necessary. Some of the filter behavior can be changes by registry settings. It is very simple to use, yet can be personalized to suit your needs.
Flate Compression and PDF
The flate compression methods for PDF are based on the public-somain zlib/deflate compression. Compression either involves binary data or ASCII text. Although this is the case, binary data is always produced regardless of text. Flate encoding output is usually very compact when compared to other methods used. You can control many aspects of flate compression. This lets you better suit your needs when it comes to what you want out of function. You can select the actual compression type, image size, quality options, size option for color, and grayscale and monochrome images.
