I want the user to insert a imagem in a cell, and based on that image I can resize the cell, but I see no way to retrieve that data using the classes CellImage and CellImageBuilder, any Idea?
ask them to input the URL of the image, instead of the image itself. Then use the =IMAGE function to show it, using the mode parameter to auto-resize– OrenJun 15, 2022 at 20:32
I don't believe this is possible at the moment. See this issue: https://issuetracker.google.com/issues/215575446?pli=1
