in reply to How to keep Imager's image files small ?

Looking into it a little further, it seems that Imager can write Windows .BMP files with 4-bits per pel.

However, as it doesn't support compressing those images, the file sizes will likely be much larger than the same image written as 8-bit palettised in .png, .gif or .jpg format

    Imager doesn't compress BMP files at all, though it can read BI_RLE4 and BI_RLE8 compressed images.

    It never seemed worth the effort of implementation, with so many formats with useful compression algorithms.
