Branch: CURRENT, Version: 1.78, Package name: gifsicle-1.78, Maintainer: pkgsrc-users

Gifsicle is a UNIX command-line tool for creating, editing, and getting
information about GIF images and animations. You can also extract frames from
animations, or replace, delete, or insert frames into existing animations.

Some more gifsicle features:
- Batch mode for changing GIFs in place.
- Prints detailed information about GIFs, including comments.
- Control over interlacing, comments, looping, transparency...
- Creates well-behaved GIFs: removes redundant colors, only uses
local color tables if it absolutely has to (local color tables
waste space and can cause viewing artifacts), etc.
- It can shrink colormaps and change images to use the Web-safe
palette (or any colormap you choose).
- It can optimize your animations! This stores only the changed
portion of each frame, and can radically shrink your GIFs. You
can also use transparency to make them even smaller. Gifsicle's
optimizer is pretty powerful, and usually reduces animations
to within a couple bytes of the best commercial optimizers.
- Unoptimizing animations, which makes them easier to edit.

Two other programs are included with gifsicle: gifview is a lightweight
animated-GIF viewer which can show animations as slideshows or in real
time, and gifdiff compares two GIFs for identical visual appearance.

Log message:
Update to 1.78. From the changelog:

* Correct an optimization bug introduced in 1.76. Reported by Tom
* Major improvements to color selection (important when reducing
  colormap size). Use gamma-corrected colors in selection and
  dithering; this makes image quality much better. Also, when reducing
  colors with dithering, prefer to select colors that dithering can't
* Add ordered dithering modes, which avoid animation artifacts. The
  default ordered dithering mode (`--dither=ordered`) is a novel mode
  that combines some of the visual advantages of error diffusion with
  the artifact avoidance of ordered dithering.
* Add halftone dithering (`--dither=halftone`).
* gifview: Improved cache memory management for better animations.
  Collect memory for old frames based on an explicit --memory-limit
  (default 40MB).
* gifview: Add `--fallback-delay` option, to specify a fallback delay
  for frames with delay 0. Thanks to Sung Pae.
* Fix `-O2` crashes introduced with `--resize` improvements. Reported
  by Bryan Stillwell.
* Improve `--careful` (fewer crashes). Reported by Bryan Stillwell.
* Improve `-O2`: again, don't refuse to optimize images with local
  color tables. Reported by Bryan Stillwell.
* Greatly improve `--dither` speed.
* Improve `--resize` behavior: avoid animation artifacts due to
  different rounding decisions. Also speed it up. Reported by Bryan
* Fix bug where `-O2` would refuse to optimize some images with local
  color tables, claiming that "more than 256 colors were required".
  What was really required is previous disposal. Reported by Bryan
* Fix crash bugs on some combinations of `--crop` and `--resize`
  (prevalent on images whose first frame didn't cover the whole
  logical screen). Reported by Bryan Stillwell.
