Mirco Miranda 63e21ee5f3 Disable JXR plugin due to crashes in JXRLIB 
I ran a simple fuzzer on all the plugins in the repo and the JXR one crashes every few seconds. I attach some files (I have many more) that cause the crashes. For the moment I think it's best to keep it deactivated.

The strange thing is that for the same plugin I had created the PR on oss-fuzz which ran locally for over an hour without problems. I'm a bit confused.

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)
  • Camera RAW images (arw, cr2, cr3, dcs, dng, ...)
  • Gimp (xcf)
  • Krita (kra)
  • OpenRaster (ora)
  • Pixar raster (pxr)
  • Portable FloatMap (pfm)
  • Photoshop documents (psd, psb, pdd, psdt)
  • Radiance HDR (hdr)
  • Sun Raster (im1, im8, im24, im32, ras, sun)

The following image formats have read and write support:

  • AV1 Image File Format (avif)
  • Encapsulated PostScript (eps)
  • High Efficiency Image File Format (heif). Can be enabled with the KIMAGEFORMATS_HEIF build option.
  • JPEG XL (jxl)
  • JPEG XR (jxr). Can be enabled with the KIMAGEFORMATS_JXR build option.
  • OpenEXR (exr)
  • Personal Computer Exchange (pcx)
  • Quite OK Image format (qoi)
  • SGI images (rgb, rgba, sgi, bw)
  • Softimage PIC (pic)
  • Targa (tga): supports more formats than Qt's version

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.

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.
