Example of working while converting to JPG file format:
JPG file format supports the following color spaces: grayscale
(8 bpp), truecolor (24 bpp, 32 bpp).
Source images:
- color image with any color depth up to 24 bpp (for instance
8 bit GIF file or 24-bit bitmap) will be converted to 24 bit color
JPG file
- color image with color depth more then 24 bit per pixel will
be converted to 32-bit color JPG;
- grayscale or black and white image regardless of its color depth
will be converted to 8 bit grayscale JPG;
This feature allows to automaticaly get images with optimal ratio
of size/color or size/quality;
- added writing support of progressive JPG;
- added support of EXIF data block in JPG file. This data block
is added to image file by digital photo camera. Now 2JPEG allows
you to keep this data at JPG to JPG conversion.
