Browse source 
This is useful in environments such as esp-idf, where the component name is something awkward like __esp_idf_main or so.

A scale factor specified this way will also be used to pre-scale images and glyphs when used in combination
with [Resource Embedding](#resource-embedding).
## Bundle translations
## Bundle Translations
Translations can either be done using `gettext` at runtime, or by bundling all the translated strings
directly into the binary, by embedding them in the generated C++ code.

## Translation Domain
By default, the domain used for translations is the name of the CMake target the `.slint` files are targeted with.
Use the `SLINT_TRANSLATION_DOMAIN` target property to override this and use the specified value as domain, instead.
This is useful in build environments where the target name is given and not suitable, such as esp-idf.
