NOTE: JFIF 4:1:1 and 4:2:2 formats use subsampling for the color components. (12 and 16-bit grayscale images are only supported in the Document and Medical Imaging toolkits.)īoth JPEG 4:4:4 and Lossless JPEG will be recognized when getting file information. Before saving a file using Lossless JPEG, make sure your reader supports it. Please note that not all applications support Lossless JPEG. LEADTOOLS supports 8, 12, and 16-bit grayscale and 24-bit color spacing. This is the JPEG File Interchange Format. LEADTOOLS supports YUV, CIELab and CMYK 4:4:4, 4:2:2, and 4:1:1 color spacing, and YUV 4:0:0 for grayscale. In this format you can read and write 8 or 24 bits per pixel, where 8 is for grayscale and 24 is for color. Therefore, in a paint-while-load routine, you can display the whole image, then progressively clarify it as the rest of the file loads.
#Convert j2k to jpg full#
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. (12 and 16-bit grayscale images are only supported in the Document and Medical Imaging toolkits.) In addition, LEAD also supports CMW files, which use Wavelet CMP compression in 8, 12, and 16-bit grayscale and 24-bit color. This format results in smaller files and better image quality than industry-standard formats. This is the LEAD CMP compressed format for grayscale and color images. LEADTOOLS reads and writes the following LEAD and JPEG compressed formats:
