The HDR QImageIOHandler plugin only supports the default image orientation (-Y +X) in .hdr files. It mixes up the width and height however, resulting in non-square images not loading. This fix adds a check for the standard image orientation in the file and returns false (with error message) if that fails. If it succeeds, it takes the height from the -Y component, and the width from the +X component, resulting in successful loading of the image. Add autotest images for landscape and portrait HDR (Radiance RGBE) loader BUGS: 433877 |

KImageFormats
Plugins to allow QImage to support extra file formats.
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:
- Animated Windows cursors (ani)
- Gimp (xcf)
- OpenEXR (exr)
- Photoshop documents (psd)
- Sun Raster (ras)
The following image formats have read and write support:
- AV1 Image File Format (AVIF)
- Encapsulated PostScript (eps)
- 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.
