--- Comment #21 from caulier.gil...@gmail.com --- If i understand the thread in libraw forum, the Thumbnail Thread interface in digiKam do not take the largest preview to render the thumb in icon view. Typically, ORF is based on TIFF/EP, and the first thumbnail returned in a small one from Exif thumbnail tags. We need to check this image size to see if it enough largest accordingly with thumbnail max size set in config dialog (typically 256 or 512). If the condition is false, we must take the preview JPEG embeddedin RAW files. The code relevant is in this file : https://quickgit.kde.org/?p=digikam.git&a=blob&f=libs%2Fthreadimageio%2Fthumbnailcreator.cpp The main wrapper is in ThumbnailCreator::createThumbnail(), which will call ThumbnailCreator::loadImagePreview(). This method will use Exiv2 API to get preview. I think the problem is here with ORF because it take Exif thumb, not preview. We must check if image size taken with Exiv2 is enough large, if not QImage returned must be null. Later in ThumbnailCreator::createThumbnail(), we will try with libraw through DRawDecoder::loadEmbeddedPreview(). This must do the stuff properly.
