The color value of the image.

The color value of the image.

Some pictures cannot be opened in earlier versions of IE8 or earlier browsers, but the data such as the file bytes is found to be completely normal through packet capture. It can basically indicate that the file is loaded as OK, the problem lies in browser rendering, but I cannot figure out what the problem is. I did not find the corresponding explanation on the Internet. After verification by multiple parties, I found that it was caused by the color value of the image, in short, it is caused by the difference between RGB and CMYK.

CMYK: print color mode

In earlier versions of IE, the color values of CMYK are not compatible, so images cannot be rendered.

It is the most extensive image print format across Mac and PC platforms. TIFF adopts LZW lossless compression, greatly reducing the image size. In addition, the most exciting feature of the TIFF format is the ability to store channels, which is very good for you to process images.
