-===== Transforming Data Formats =====
-The a.m. ''dokuwiki-logo.svg'' DokuWiki Logo is provided in SVG data format quite appropriately. The [[wp>SVG | Scalable Vector Graphics (SVG)]] is an vector image format for defining two-dimensional graphics, providing excellent support for interactivity and animation.
-However, there may be the need to provide other graphical data formats for both compatibility and usability reasons. Please read the a.m. [[https://stackoverflow.com/a/48969053 | article]] for background information.
-==== MS-Windows ====
-Please follow the [[http://www.graphicsmagick.org/INSTALL-windows.html | GraphicsMagick Windows Installation]] procedure. After successful installation select "//Command Prompt//" from the Windows Start menu((One may consult the article [[https://www.lifewire.com/how-to-open-command-prompt-2618089 | How to Open Command Prompt (Windows 11, 10, 8, 7, etc.)]] if unsure.)) and within the window type:
-  gm convert input.gif output.png
-Quite similar to the GNU/Linux example described below.
-==== GNU/Linux ====
-The Debian GNU/Linux package [[https://packages.debian.org/bookworm/graphicsmagick | graphicsmagick]] provides a set of graphic tools aiming at stability.
-  gm convert input.gif output.png
-The above command would just transform and copy the ''input.gif'' GIF to a new ''output.png'' PNG file. Please be aware of many more options as GraphicsMagick's //gm// provides a full suite of utilities for creating, comparing, converting, editing, and displaying images.
-==== Mac OS X / macOS ====
-Transforming several files over a range of graphical data formats is easily supported by help of the CLI((This operation needs the Command Line Interface (CLI) by help of the Apple Terminal app and please first read the [[https://support.apple.com/guide/terminal/welcome/mac | Terminal User Guide for Mac - Apple Support]] if unsure.)) tool //SIPS// on Mac OS X / macOS out of the box e.g., as follows:
-  sips -s format png ./*.gif --out mypng-folder
-The above command would collect any GIF files in the working directory i.e. the current folder and would produce a new sub-folder containing the new PNG files in the result of graphical transformation. By help of ''man sips'' one may read the applicable manual page on Apple Mac OS X / macOS first.
-===== Legacy =====
-==== SVG Data Format ====
-Obviously, the a.m. ''dokuwiki-logo.svg'' DokuWiki Logo was created in an older version of Inkscape (90 DPI) and we need to make it compatible with newer versions (96 DPI). Thus "Scaling the whole document -- This file contains digital artwork for screen display" would be the most appropriate option for this document in the current [[https://inkscape.org/release/inkscape-1.3.2/ | Inkscape 1.3.2 release]].
-==== GIF & PNG ====
-One may recall the former [[wp>GIF#Unisys_and_LZW_patent_enforcement | Unisys and LZW patent enforcement]]
-discussion concerning the legal availability of the GIF data format. Nevertheless, the [[wp>Lempel–Ziv–Welch | Lempel–Ziv–Welch (LZW)]] class of lossless data-compression algorithms itself (and consequently GIF) have been free to use since July 2004.
-However, the [[wp>PNG | Portable Network Graphics (PNG)]] was designed as a replacement for GIF during that time. Please note PNG offers better compression and more features than GIF, with animation being the only significant exception apparently. Nevertheless, a specially crafted GIF like the a.m. ''dokuwiki-16.gif'' document can offer an excellent choice and till today is state of the art.
