As far as I know, the ability to use the KHTML part in Konqueror was removed, leaving only the QtWebEngine part. KHTML was already in pure maintenance mode in kf5, for kf6 it got removed, there will be no future work spend on this beside critical security issues, if at all. |
Hello, I am author of github.com/novomesk/qt-avif-image-plugin AVIF is a new image format based on AV1 compression. Firefox has support for AVIF (but disabled by default), Google is working to add support into Chrome. Even before Firefox, Konqueror was able to display AVIF in websites after following trivial patch in khtml: www.reddit.com/r/AV1/comments/faayy9/avif_image_browser_test/ I propose following changes in src/imload/decoders/qimageioloader.cpp: 1) In bool isSupportedFormat(QString format) Check if AVIF is listed in QImageWriter::supportedImageFormats() and mark AVIF as supported (return true). 2) In bool imageFormat(QImage &image, ImageFormat &format) in default switch case - instead assuming "unsupported formats", what about converting them to supported? if ( image.hasAlphaChannel() ) { image = image.convertToFormat( QImage::Format_ARGB32 ); format.type = ImageFormat::Image_ARGB_32_DontPremult; } else { image = image.convertToFormat( QImage::Format_RGB32 ); format.type = ImageFormat::Image_RGB_32; } AVIF test files here: github.com/AOMediaCodec/av1-avif/tree/master/testFiles
