            Bug ID: 114533
           Summary: add support for FLIF image format (image import and
                    inside .ods/.odt)
           Product: LibreOffice
           Version: 6.0.0.0.beta2
          Hardware: x86-64 (AMD64)
                OS: Windows (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: filters and storage
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: squeezechart at gmx.de

please add support for FLIF image format (image import and inside .ods/.odt)

http://flif.info/

It is a modern, free and open image format (LGPLv3 license).

FLIF is a novel lossless image format which outperforms PNG, lossless WebP,
lossless BPG, lossless JPEG2000, and lossless JPEG XR in terms of compression
ratio.

According to the compression experiments we have performed [older results
here], FLIF files are on average:

    14% smaller than lossless WebP,
    22% smaller than lossless BPG,
    33% smaller than brute-force crushed PNG files (using ZopfliPNG),
    43% smaller than typical PNG files,
    46% smaller than optimized Adam7-interlaced PNG files,
    53% smaller than lossless JPEG 2000 compression,
    74% smaller than lossless JPEG XR compression.
