Settings:~/config/settings/* - Every Translator creates its own settings file here after you've changes its defaults.
~/config/settings/system/DataTranslations settings - Stores the panel's window position.

Every application has the ability to open and save every file format for which there's a Translator installed. The settings for these Translators are configured in the DataTranslations preferences.


Depending on its capabilities, each Translator offers different settings. At least you'll get an Info... button that opens a window with the credits and the installation path.
The following table gives an overview of the default Translators and their most useful options.

Apple iconsValid image sizes are 16, 32, 48, 128, 256, 512, 1024 (RGB32 and RGBA32)
BMP images24bit, uncompressed, no transparency
EXR imagesILM's high dynamic-range (HDR) format
GIF images8bit, lossless compression, transparency
You can reduce the filesize by limiting the number of used colors and the palette.
You can write images with transparency, either by automatically using the alpha channel or by setting the RGB value that will be transparent by hand.
HVIF iconsTranslator for Haiku's vector icon format
JPEG2000 images24bit, compressed, no transparency
Here, you normally only care about the output quality.

Besides the output quality you can also set a smoothing that will lessen compression artefacts but can blur the picture a little.

Photoshop images32bit, lossless compression, transparency
The translator reduces all layers to one bitmap layer.

Screenshots, charts, black&white drawings and other images with few used colors, as well as small pictures are best saved as GIF (up to 256 colors) or PNG (millions of colors). JPEG, for example, introduces compression artefacts without gain in smaller filesize.
