.PGF

Progressive Graphics File

📌 First of all, the .PGF file interpretation can be directly associated with a bitmap image generated and opened up in the Progressive Graphics File (briefly, PGF) schema formation. Accurately, this appropriate .PGF approach is consistent with lossless and lossy compression algorithms and a huge arsenal of color models, such as CMYK color, l*a*b color, ARGB color, RGB color, grayscale, and indexed color (256 palette size).

From the very start, the .PGF principle was intended and targeted for improving on the JPEG standard by increasing outcome compression ratios and reducing archival time expenses. Besides, the .PGF extension arrangement provides progressive, intelligent transmission, which implies the image can be properly viewed at a low quality ratio before all of its associated contents are completely downloaded, and after a while the quality increases as more data is obtained from the server. The noted .PGF data layout also sustains representation of multiple resolutions, which implies that it does not require to store and maintain separate distinguished preview graphics (for instance, thumbnails).

The .PGF algorithm was invented at the same time period as the JPEG 2000 specification and was initially announced and published in 2000, as well. The technological .PGF make-up was invented at the Institute of Theoretical Computer Science at ETH Zurich university.

Pokémon Mystery Gift for Black & White File

📌 In rarer occasions, the .PGF approach may be established on the basis of a game file exploited and opened by Pokémon White and Pokémon Black, the fifth revision of game series dedicated to the Pokémon franchise for the Nintendo DS portable consoles. Particularly, this respective .PGF record variation encompasses data for a mystery gift, which can be given to other game players to unlock custom events and items in the game.

Traditionally, the .PGF data elements are allocated within Pokémon saved games (.SAV branch nodes) on genuine Nintendo DS cartridges. At last, the .PGF entities can also be adjusted and imported into a proper .SAV sample using the Pokémon Mystery Gift Editor or Pokesav utilities.

How to open an .PGF file?

📌 The .PGF make-up interpretations can be easily retrieved, explored, examined, and opened by NCH Software PhotoPad Photo Editor, Lemkesoft GraphicConverter or libPGF utilities supported by all major desktop operating platforms and architectures. Quite seldom, it can be suggested to take service of Pokémon Mystery Gift Editor, able to import .PGF file elements into accustomed Nintendo DS saved game instances, packaged into .SAV entry representations.
