I am working with transparent Bitmap symbols in my drawing and having some issues when exporting the file to pdf. For reference, I am exporting several plans as pdfs in Vectorworks and the symbols appear as they do in my viewport (no issues with graphics transparency), however when I PDF the presentation that has the exported pdfs as links in Adobe InDesign, I am presented with the issue below (bitmap background graphics showing)
I have tried exporting as jpegs, which solves the transparency issue in my final PDF. But the file sizes are just too large, and compressing them I lose a lot of quality. Any help would be much appreciated!
