This directory contains released distributions of GraphicsMagick for
Microsoft Windows XP or later (XP, Vista, 7, 8, and 10).

The GraphicsMagick 1.3.?? distribution is based on the
"GraphicsMagick-1_3_??" tag on the "GraphicsMagick-1_3" branch in
GraphicsMagick Mercurial.

If the file has "Q8" in the name, then it is compiled to support 24/32
bit pixels. If the file has "Q16" in the name, then it is compiled to
support 48/64 bit pixels. Most users will find that the "Q8" builds
are sufficient for their needs. They execute faster than the "Q16"
builds and take less memory. Users who are using CMS color profiles,
or are processing scientific/medical/film images will want to use a
"Q16" build. Binaries are built using Microsoft Visual Studio 2008
Professional Edition with OpenMP enabled and are tested under Windows
10.

The source package compiles using Microsoft compilers as old as Visual
C++ 6.0 (released in 1998!) and is reported to compile using the
latest Visual Studio editions.

For Windows packages, the downloaded executable should be executed to
start the graphical installer.

A summary of the installable files is as follows:
