Image File Formats: LEAD CMP and JPEG

JPEG and LEAD Compressed (JPG and CMP)

LEADTOOLS reads and writes the following LEAD CMP and JPEG compressed formats:

LEAD
This is the LEAD CMP compressed format for grayscale and color images. This format results in smaller files and better image quality than industry-standard formats.

Progressive LEAD
This is a LEAD format that is useful for transmitting images, because the first part of the file contains the full dimensions of the image. Therefore, in a paint-while-load routine, you can display the whole image, then progressively clarify it as the rest of the file loads. In this format, you can read and write 8 or 24 bits per pixel, where 8 is for grayscale and 24 is for color.

Lossy JFIF
This is the JPEG File Interchange Format. LEADTOOLS supports LAB 4:4:4, 4:2:2, 4:1:1, YUV 4:4:4, 4:2:2, and 4:1:1 color spacing, and YUV 4:0:0 for grayscale. LEADTOOLS supports thumbnails and comments.

Lossless JFIF This is the JPEG File Interchange Format. LEADTOOLS supports 8, 12, and 16-bit grayscale and 24-bit color spacing.

12 and 16-bit grayscale images are only supported in the Medical Imaging editions.

Progressive JFIF This is a JFIF format that is useful for transmitting images, because the first part of the file contains the full dimensions of the image. Therefore, in a paint-while-load routine, you can display the whole image, then progressively clarify it as the rest of the file loads. LEADTOOLS supports LAB 4:4:4, 4:2:2, 4:1:1, YUV 4:4:4, 4:2:2, and 4:1:1 color spacing, and YUV 4:0:0 for grayscale.

Lossy JTIF This is the JPEG Tagged Interchange Format. LEADTOOLS supports LAB 4:4:4, 4:2:2, 4:1:1, YUV 4:4:4, 4:2:2, and 4:1:1 color spacings, and YUV 4:0:0 for grayscale. LEADTOOLS offers multipage support as well as reading and writing of TIFF tags.

Lossless JTIF This is the JPEG Tagged Interchange Format. LEADTOOLS supports 8, 12, and 16-bit grayscale and 24-bit color spacing. LEADTOOLS offers multipage support as well as reading and writing of TIFF tags. Both TIFF JPEG 4:4:4 and Lossless JPEG will be recognized when getting file information.

12 and 16-bit grayscale images are only supported in the Medical Imaging editions.
