Features

• New directories can be added by the File > Add Directories menu.

• New single image can be added by the File > Add Image menu.

• New tags can be added by the File > Add Tags menu. All characters are allowed except semicolons, which are used to separate tags. In the dialog, enter the tags you want separated by semicolons. You'll see buttons get added to the dialog as you type a tag and then a semicolon. Note that even if you want to add a single tag, you'll have to end it with a semicolon to actually add it.

• Tags are displayed on the left. These can be filtered by typing in the box above the section. Filtering tags by multiple strings is possible by separating the strings by semicolons. Two methods of tag filtering are available: OR and AND.

• Added images are displayed on the right. These can be filtered by name by typing in the box above the section.

• Tags can be linked to an image by dragging and dropping them on the desired image. Multiple tags can be selected and dropped at once.

• Images can be filtered by tags by selecting desired tags and clicking the Filter images button below the tag section. Two methods of filtering are available: OR and AND.

• Images can be filtered by the directory they're in by selecting directories in the dropdown menu above the images section.

• Show untagged images only checkbox can be checked to show only images without any linked tags. If any tag is selected in the tag list, this checkbox is disabled. As a result, this can only be used without any tags selected (because if you have a tag already selected, it means you are about to/already have images filtered by tags, making this useless).

• Tags linked to an image can be viewed by right clicking an image and selecting Show Tags. A tag can be removed from an image by clicking on its button and then confirming. The tags will not get removed unless you press OK after removing desired tags.

• An image can be opened in the default image viewing application by double-clicking on it.

• Images can be dragged and dropped to any location that supports dropping images (file managers, browsers, etc).

• Images can be removed from the database by right-clicking, selecting Remove Image and confirming. This won't delete files on disk.

• Note: To deselect an item (tag or image), press Ctrl and click the left mouse button. To deselect all tags, press Ctrl+X.

• Ctrl+I: Open Add image menu.

Image formats

All image formats supported natively by QImageReader are supported. Additional image formats are supported through QT image formats plugins (webp and tiff).

Some common RAW image formats (cr2, nef and dng) are read by the tiff plugin.

Adding image formats

Additional image formats, if supported by other plugins installed on your system, can be added by adding the extensions to the fileTypes list in the include/filetypes.h header file.

For instance, if support for crw, arw or raf files are needed, just install the QTRaw plugin and add the extensions to the fileTypes list.

Note: If QTRaw is installed, cr2, nef and dng files will also be read through it. And QTRaw seems like it could be improved a lot. It seems to "auto-rotate" portrait images which look odd in the thumbnails. So, I'd suggest against using it. The QT tiff plugin seems to be a lot better, albeit a little slower.

Building and Installing

For all image format support, it's recommended to install the QT image formats plugins. Under debian and derivatives, they can be installed with:

sudo apt-get install qt5-image-formats-plugins

After installing the plugins, run the following commands to build and install:

qmake && make
sudo make install
