The Scale block is for scaling up or down a JPEG or PNG image while maintaining the width/height ratio. The factor 100 will result in unchanged dimensions. Anything smaller will reduce the image dimensions. E.g. 50 will result in half the height and width. Larger values will scale up the image, as a side effect it will get blurry then.
Use cases
- Preparing user generated (e.g. signature) or downloaded (probably dynamically generated) images for reduced output, e.g. a thumb preview.
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 100 lets you pick the scale factor. You can also set a variable with numerical content, which then is rounded to the next multiple of 90.
