I've made a quick sun graphic for a portfolio in illustrator that is pixelated when I zoom in and when I import it into InDesign. I can't seem to make the geometry a vector or find any answers as to how to fix the pixelation.
InDesign is using a
Typical Display setting by default, to speed things up, which is especially useful when working on large files with a lot of external links.
However, you can hit CTRL+ALT+H and this switches to the
High Quality Display setting, which will render your imported Illustrator file in full sharpness.
I did Lucian's response for InDesign and still had issues, but I went back to Illustrator > highlighted image > effects > Document raster effect settings > changed the resolution to high > export selection > change to png and changed the scale to resolution and got the image to come out cleanly when imported to InDesign.
