Although TIFF-format is not as common as the popular JPEG and PNG, it often raises questions among those who faced him before.Indeed, is it not sufficient for image processing use RAW, obtained from the cameras, BMP and "proprietary" format with Photoshop CorelDraw (PSD and CDR)?What is a TIFF file format, and where to use it?Let's try to answer these questions.
mysterious abbreviation TIFF
format for images tagged (Tagged Image File Format) was developed by Aldus specifically to store scanned images.It should be noted that it is used for raster graphics, t. E. Images representing a grid of pixels.The fact that this compression algorithm is tagged, meaning that it uses special extended and basic tags.Recent form the core of the format and supports all applications that are able to work with him.This type of image data has become very popular for sharing and storing images that have a greater depth of color.TIFF-format is often used in the printing industry, with OCR, faxing, scanning.It should be noted that the maximum weight of a document saved in this way can not exceed 4 GB.And to open the file TIFF, the size of which is greater than 2 GB will likely need to run Photoshop CS, or one of the later versions of it, as most of the other applications are unlikely to be able to cope with it.
What features has the TIFF-format
structure of the algorithm is quite flexible, and it gives you the ability to save images in different color modes:
- grayscale;
- binary (black and white);
- with indexed palette;
- CMYK;
- CIE Lab;
- YCbCr;
- RGB.
As for compression, the user has the ability to both give it up, and choose one of the following algorithms:
- CCITT Group (3 or 4);
- JBIG;
- LZ77;
- PackBits (RLE);
- JPEG;
- LZ77;
- LZW.
This image format "Photoshop" is able to keep the layers, transparency, notes and details of the pyramids with a dynamic resolution.However, when you open this document in another graphics application, it is likely to be considered only as a flattened image.
How to open TIFF-format images
