Codecs For Image

The Image codecs is a method of compression/decompression of image files or image data. The codecs stands for Coders / Decoders.

The various software image codecs are:

• Bmp
• Gif
• JPEG
• JPEG 2000
• MJPEG
• TIFF
• PNG
• WBMP

BMP

- Good photo quality.

- Bitmap codecs may translate well to dot-format output devices such as CRTs and printers.

GIF

- This codecs allows you to create transparent, interlaced, and animated graphics for the Web.

- This codec is not good for photographic images due to its limited number of colors generally 256 colors.

JPEG

- JPEG codec has low complexity. Picture quality is generally good enough.

- This is also memory efficient. i.e. good compression allows to reduce the file size.

JPEG 2000

- Improved coding efficiency.

- Full quality scalability.

- Improved error resilience compared to jpeg.

MJPEG

- MJPEG codecs are often used as storage formats for large files that need to be archived with good quality. 

- It is a lossy codec, but at 100% quality, the image degradation is minimal.

TIFF

- Compared to a JPEG, an uncompressed TIFF codec retains the best quality of a photographic image, making it ideal for digital masters and print documents.

- Encoding scheme is lossless; files can be compressed or uncompressed.

PNG

- It is a best one for creating complex live transparency, high-color graphics, and better compressed low-color graphics.

- Designed to be network-friendly, so it is recognized and supported on all platforms.

- It doesn’t support animation
