🟦 Background image

The Background Image block allows you to dynamically modify the background of your application with customizable animation effects.

This block is ideal for creating fluid visual transitions between different settings or for adapting the graphic atmosphere according to the user context.

📥 Entries

• background (Image): The image to display in the background. It automatically adapts to the size of the screen in “contain” mode and allows you to configure the background color, repetition (mosaic or single) and position.
• duration (Number): Duration of the transition animation in seconds (default 0 for immediate change).
• inEffect (Choice): Appearance effect of the new image (options: None, Zoom, Zoom out, Fade, Slide).
• outEffect (Choice): Effect of disappearance of the old image.
• text: Optional text to display over the background.
• textPosition (Choice): Position of the text (Left, Right, Center - by default Right).

📤 Outings

• out (Stream): Output flow to continue the course after the background change.
