Png File

Since not all graphic formats are of equal complexity, author John Miano does not simply choose a number of file formats and devote a chapter to each one. Instead, he offers additional coverage for the more complex image file formats like PNG (a new standard) and JPEG, while providing all information necessary to use the simpler file formats. While including the well-documented BMP, XBM, and GIF formats for completeness, along with some of their less-covered features, this book gives the most space to the more intricate PNG and JPEG, from basic concepts to creating and reading actual files.

Providing a look ahead at some of the most promising innovations in graphics technologies, this guide covers the GDI+ graphical library, the .NET Framework platform, C#, and the DirectX library. Theoretical aspects of graphics, algorithms for solving common problems, and examples of their practical implementation are covered. The support of popular graphic file formats, such as BMP, GIF, TIFF, JPEG, EXI, PNG, ICO, WMF, and EMF, as well as bitmap redrawing with the application of the external alpha channel are discussed. Resizing, stretching, distorting, and rotating bitmaps are addressed in detail, as is gradient filling and support for transparency.

Tagged Image File Format - Tagged Image File Format (abbreviated TIFF) is a file format for mainly storing raster images, including photographs and line art. Originally created by the company Aldus for use with PostScript printing, TIFF is a popular format for high color depth images, along with JPEG and PNG.

APNG - The APNG (Animated Portable Network Graphics) file format is a proposed extension to the portable network graphics (PNG) specification that would allow for animated PNG files that work in a similar fashion to animated graphics interchange format (GIF) files, while retaining the backward compatibility with non-animated PNG files.

File Allocation Table - File Allocation Table (FAT) is a patented file system (patents apply to technology supporting Long File Names within the file system, but not the core file system itself) that was developed by Microsoft for MS-DOS and is the primary file system for consumer versions of Microsoft Windows up to and including Windows Me. The FAT file system is considered relative

File dialog - In computing, a file dialog (Also called File Selector/Chooser, or open and save dialog) is a dialog box that allows users to choose a file from the file system. File dialogs differ from file managers as they are not intended for file management (although some offer simple operations such as folder creation), rather they are intended for the opening and saving of files.

The motivation for creating the PNG format came in early 1995, after Unisys terminated its royalty-free patent licenses to developers of free software and non-commercial software. PNG is now an International Standard (ISO/IEC 15948:2003), also released as a W3C Reco... The algorithm is described in U.S. Patent 4,558,302 and other patents around the world. Version 1.0 of the shortcomings of the PNG specification was released on 31 December 1998. Although GIF allows for animation, it was decided that PNG should be a single-image format. On most images, PNG can achieve greater compression than GIF, but some implementations make poor choices of filter methods and therefore produce unnecessarily large PNG files. Other image attributes that can be stored in PNG files include gamma values, background color, and textual information. However, the GIF format which made a replacement desirable, notably its limitation to 256 colours at a time when computers capable of displaying far more than 256 colours at a time when computers capable of displaying far more than 256 colours png file.
