This block is used for making a certain color of a JPEG or PNG image transparent. The output image will always be a PNG image, because standard JPEG does not support transparency.
Use cases
- Preparing an image for use as an overlay.
Configuration
Clicking on given file in the title of the building block lets you pick the desired image from your Google Drive.
You can deselect the picked image by clicking on the x button on the right of the selected filename.
If no image has been picked, Ultradox will load the given image that is stored in the input variable.
When loading files stored in a variable, make sure that the input prefix matches the output prefix of the building block that provides the document.
Clicking on the color “#ffffff” lets you configure the color to be replaced. The color format is in “Hex triplet”.
