bitmaps/
This folder is for bitmap files.
bitmaps/models/
This folder is for user model images that are configured in ‘Model / Edit model’ and the
new model wizards.
bitmaps/user/
This folder is for user bitmaps other than the model images set up in ‘Model / Edit
model’.
The recommended image format is the following BMP format:
32bits BMP format
8 bits per color
Alpha channel (used for image transparency)
Size: 300x280px
This format reduces the computational load on the on-board microcontroller of the
X20. Additionally, ETHOS will resize BMPs on the fly, but not PNG or JPG.
Image file naming rules:
Rule 1: use only the following characters: A-Z, a-z, 0-9, ()!-_@#;[]+= and Space
Rule 2: the name must not contain more than 11 characters, plus 4 for the
extension. If the name is longer than 11 characters, it is displayed in the File
Manager but does not appear in the model image selection interface.
