Transparent
AI-generatedSummary
Make pixels matching the selected color transparent in the source image. The node processes the binary image and returns it in the configured output format and binary property.
Inputs
- Input Property Name (required) — Binary property containing the source image; defaults to
data. - Color (required) — Target color to make transparent; defaults to
#ff0000ff. - Tolerance — Color matching tolerance; defaults to 0, which matches only the exact target color. The implementation compares summed RGBA channel differences against four times this value.
- Options — Optional output settings: choose a binary property name for the result, set a file name, override the output format, set quality, or choose the background used when exporting to formats without alpha support.
Output shape
A single n8n item per input item, containing the original JSON and the processed image as binary data.
By default, the processed image is written to the input binary property; an output property name can direct it to a different key. Output format defaults to the input format, and JPEG export flattens transparency onto the configured background color. Errors are thrown unless Continue On Fail is enabled.
