[What is and isn't possible when writing plugins]

Thanks for your answer, midora. So I will have to stick to my calculator until I find a better possibility.
Is there a documentation for this class you mentioned?

[What is and isn't possible when writing plugins]

Hi there!

Are effects able to read out a selection's dimensions in inch or millimeter and resize an image to a certain dimensions? Or: can effects read out the selection's dimensions in pixel and the resolution of the whole image in dpi and calculate a factor for resizing?

Background: I need to resize companies' logos to prepare them to get converted into embroidery programms. So certain elements (for example text) must not be below a height of 5 millimeters. For example: I want to make a selection around the letter "M" (which has a height of 16 millimeters) inside a random logo and enter the desired height of 5 millimeters -> the whole image will be reseized to 31,25% to meet the requirement of the selected letter "M" being 5 millimeters in height.

Thanks in advance for answering
