The way Pro 3.5 export layout that contain cached raster to jpeg (or pdf) changed in 3.5 from 3.1 or ArcMap
With the old version when you set the dpi to 300 Pro “know” to ask the raster for better resolution. So when you zoom into the result jpeg you will see more details.
With 3.5 the scale define what level will be exported from the raster.
This is described in this blog: https://gis.utah.gov/blog/2025-01-30-better-resolution-discover-exports/
This is a good idea when you need to print but it is not so good when you need digital file that you can zoom into.
The blog describes some solution but I wonder is there a simple way to solve it (some checkbox to return to the old way maybe?)
Thanks
