Converts strings to numbers.

Inputs:

• string: Input string
• rounding: Rounding method

TextRandomMultiline

Randomizes the order of lines in a multiline string.

Inputs:

• text: Input text
• amount: Number of lines to randomize
• seed: Random seed

TextSwitchCase

Switch between multiple cases based on a condition.

Inputs:

• switch_cases: Switch cases, separated by new lines
• condition: Condition to switch on
• default_value: Default value when no condition matches
• delimiter: Delimiter between case and value, default is :

Inpainting Nodes

PrepareImageAndMaskForInpaint

Prepares images and masks for inpainting operations. It's to mimic the behavior of the inpainting in A1111.

Inputs:

• image: Input image tensor

• width: Manually set inpaint area width. Leave 0 default to the masked area plus padding. (0-2048)
• height: Manually set inpaint area height. (0-2048)

Outputs:

• inpaint_image: Processed image for inpainting
• inpaint_mask: Processed mask
• overlay_image: Preview overlay
• crop_region: Crop coordinates (input of OverlayInpaintedImage)
