TIFF image format is known for superb image quality, but large file size. Highly flexible, platform independent, this bitmap format is widely used. TIFF supports a wide range of compression types:
The lossless algorithms that can be used are:
• PackBits
• LZW (Lempel-Ziv-Welch), popular for grayscale or color images
• CCITT Fax group 3 & 4, mainly used for line-art images
The CCITT compression standards are designed for FAX communication. ImageConverter Plus supports reading and writing of the following 1-bit formats that are commonly used in FAX transmissions:
TIFF CCITT. These are compressed TIFF files that are commonly used for FAX transmission and document imaging
TIFF CCITT Group 3. These are TIFF CCITT files in a format that is more advanced and more compressed than TIFF CCITT
TIFF CCITT Group 4. These are TIFF CCITT files in a format that is more advanced and more compressed than TIFF CCITT Group 3
JPEG is a lossy compression algorithm oriented at compressing photo-realistic full color images without any losses detected by human eye.
JBIG is designed to compress one-bit black-and-white images and can also be used to compress four-bit images.
JPEG6 algorithm is a version of JPEG algorithm.
LZW algorithm remains the most popular compression type. Its main advantage is the ability to compress images without distorting them.
