New user here, I am trying to create a frame that shows a specific part of a pdf that was inserted through DataMerge.
My goal is to have a placeholder frame "zoom in" on a specific part of a series of pdf documents that are referenced using DataMerge. I am able to get the pdf to appear, but it shows the entire image in the placeholder. I have tried using the "Fitting Options" feature to crop away until I am left with the section I want to see (preview is turned on, for both DataMerge and Fitting Options). However, after doing so, the top/bottom/left/right values reset to 0 after I do something else (like changing the preview or turning it off). Exporting the indd file immediately afterwards also resets the values, resulting in the whole pdf showing. I've tried doing this with the preview off but it still resets the values to 0.
