The BSD license goes in the relevant CMake file, and COPYING-CMAKE-SCRIPTS is removed. README.md gets a License section describing the overall license of the framework, as well as a note about the CMake scripts. As part of this commit, I release the existing autotest images (which I created myself) as public domain (or license them under CC0 where public domain does not apply), ensuring they are compatible with whatever license the package is distributed under.

# KImageFormats
|
|
|
|
Image format plugins for Qt
|
|
|
|
## Introduction
|
|
|
|
This framework provides additional image format plugins for QtGui. As
|
|
such it is not required for the compilation of any other software, but
|
|
may be a runtime requirement for Qt-based software to support certain
|
|
image formats.
|
|
|
|
## Formats
|
|
|
|
The following image formats have read-only support:
|
|
|
|
- DirectDraw Surface (dds)
|
|
- Gimp (xcf)
|
|
- OpenEXR (exr)
|
|
- Photoshop documents (psd)
|
|
- Sun Raster (ras)
|
|
|
|
The following image formats have read and write support:
|
|
|
|
- Encapsulated PostScript (eps)
|
|
- JPEG-2000 (jp2)
|
|
- Personal Computer Exchange (pcx)
|
|
- SGI images (rgb, rgba, sgi, bw)
|
|
- Softimage PIC (pic)
|
|
- Targa (tga): supports more formats than Qt's version
|
|
- XView (xv)
|
|
|
|
## Contributing
|
|
|
|
See the QImageIOPlugin documentation for information on how to write a
|
|
new plugin.
|
|
|
|
The main difference between this framework and the qimageformats module
|
|
of Qt is the license. As such, if you write an imageformat plugin and
|
|
you are willing to sign the Qt Project contributor agreement, it may be
|
|
better to submit the plugin directly to the Qt Project.
|
|
|
|
Note that the imageformat plugins provided by this module also provide a
|
|
desktop file. This is for the benefit of KImageIO in the KDE4 Support
|
|
framework.
|
|
|
|
## Duplicated Plugins
|
|
|
|
The TGA plugin supports more formats than Qt's own TGA plugin;
|
|
specifically, the one provided here supports indexed, greyscale and RLE
|
|
images (types 1-3 and 9-11), while Qt's plugin only supports type 2
|
|
(RGB) files.
|
|
|
|
The code for this cannot be contributed upstream directly because of
|
|
licensing. If anyone were willing to write fresh code to improve Qt's
|
|
TGA plugin, it would allow the TGA plugin in this framework to be
|
|
removed.
