Making an image semi-transparent

Set opacity for given file to 100


This block is for making a JPEG or PNG image semi-transparent.

Use cases

  • Preparing user generated (e.g. signature) or downloaded (probably dynamically generated) images for use as a watermark or background.


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.

Clicking on one the 100 lets you configure the opacity value. It is a percent value with 100 meaning full opacity and 0 being completely transparent.
