Description |
Nearly all digital cameras have the option to save images in JPEG format. The JPEG format supports 8 bits per color (red, green, and blue) and produces relatively small file sizes. The compression when not too severe does not detract noticeably from the image. But JPEG files can suffer generational degradation when repeatedly edited and saved. Photographic images may be better stored in a lossless non-JPEG format if they will be re-edited in future, or if the presence of small 'artifacts' is unacceptable. It is however the best format for internet publishing in most cases. |
Netpbm format is a family including the portable pixmap file format (PPM), the portable graymap file format (PGM) and the portable bitmap file format (PBM). These are ASCII files that provide very basic functionality and serve as a least-common-denominator for converting pixmap, graymap, or bitmap files between different platforms. Several applications refer to them collectively as the PNM format (portable anymap). |
