I am writing an ANI decoder from scratch so that the application loads and displays the full animation.
The ANI file format is a graphics format used for animated mouse cursors on Windows.
Currently, dView only partially supports the ANI format, because it only displays the first frame of the animation, which is not good. : |

Also, I'm going to add a color quantizer to preserve the original image quality when saving.
This is necessary for all those formats that save images in the 8 bit per pixel format (or less) causing a significant degradation of the color quality. One of them is the gif format.
The type and quality of the Windows quantizer  depend on the version of the operating system. For example, the results of the quantizing process on Windows XP and Windows 7 are totally different.

Windows XP

Windows 7 

Therefore, an external quantizer is needed to ensure that the image quality remains the same in all versions.

Thanks for reading.
