Fotoxx navigates an image collection using a thumbnail browser to choose images to view or edit. Edit functions include brightness, contrast, color, gamma, white balance, tone mapping, red eyes, sharpen, blur, noise suppression, smart erase, trim (crop), resize, rotate, add text, bend/warp, many art effects, HDR, HDF, stack, and panorama. Edit functions use movable curves and sliders. Feedback is live using the whole image. RAW files can be edited and saved with deep color. Areas or objects can be selected using freehand draw, follow edge, and tone matching. Selections can be edited in place with adjustable blending. They can also be cut and pasted into other images. Any metadata can be edited, reported, and searched (filenames, tags, dates, geotags, comments, captions, ratings, etc.). Collections (arbitrary subsets) can be defined and viewed. Batch functions are available for rename, resize/export, RAW conversion, and more.
Color space conversion is supported using LCMS (e.g. Adobe RGB <--> sRGB). A photo of a page in a thick book can be squared and flattened; the print is stretched out where the page curves down at the binding. A photo can be converted into a cartoon-like drawing. The thumbnail gallery view has three sort options: file name, file mod date, and photo date (EXIF). Metadata is kept when a RAW file is converted to TIFF/JPEG/PNG. Brightness distribution graph allows selection of colors, and reflects only the visible part of a zoomed image. One significant and three minor bugs were fixed.
The focus for this release is speed and interface improvements. Mouse-driven area-selection and edit respond much faster. Indexing of new files at startup is much faster. The exiftool program is started as a server process and left running, eliminating a significant delay for every image opened. The internal image format was changed from int-16 to float-32 per color. This simplified the code and made some edit functions slightly faster, but more memory is used: about 800 MB to edit a 20 megapixel image. There are several other small improvements, 1 significant bugfix, and 5 minor ones.
Fotoxx has been converted to use GTK3 and Cairo. It will no longer build or install on older Linux releases lacking these libraries. Support for multiple top image directories has been added. The gallery thumbnail size is saved and restored across sessions. RPM packages are now built using Fedora and rpmbuild instead of alien. Two minor bugs have been fixed.
