TIFF is a format that allows you to store raster graphics with tags. It was developed by Aldus Corporation in conjunction with Microsoft so that it can be used with PostScript. Aldus Corporation owns specifications. Subsequently, this company merged with Adobe Systems. It is she who now owns the copyright to these specifications. Typically, TIFF files (Tagged Image File Format) are with the extension .tiff or .tif. Aldus was specifically engaged in the development of the format in order to achieve the preservation of scanned images. The popularity of TIFF can be explained by the fact that it is preferred in order to store images that have a large color depth. The format is used to send faxes, scan, recognize texts. It is widely supported in the printing industry. TIFF was chosen as the main graphic format of the NeXTSTEP operating system. Then from this system TIFF support migrated to Mac OS X. At first, the format supported lossless compression. Then it was supplemented in order to support lossy compression in JPEG format. We emphasize that the maximum weight of a document, if stored in this form, is no more than 4 GB. To open a TIFF file larger than 2 GB, you must run Photoshop CS.
PBM is a raster image category file format. It is a compact single-bit black and white image. In other words, this is a simple format that allows you to store black and white pictures. It can be easily formatted into text. In this raster image format, if the pixel is a byte of one, it represents black pixels. When it is a byte from zero, it represents white pixels. The format is referred to as the Portable Bitmap Image file type. How can I open this format? To do this, use programs such as Adobe Photoshop CS, some versions of ACD Systems, as well as Newera Graphics Converter Pro, Corel PaintShop Pro X6. The file has 1 bit per pixel. PBM is a type of PPM format. PBM, that is, Portable Bitmap, is part of the Netpbm graphics package along with a couple of other formats: PGM, that is, Portable Graymap; PPM, i.e. Portable Pixelmap. Occasionally, these three formats are combined under the general name PNM (Portable Anymap). These are intermediate files used in conversion processes supported by Portable Bitmap Utilities (these are applications that have open source code). The PBM format is linked in black and white bitmap images. In PGM, grayscale bitmaps. PPM stores color bitmaps.
