I am using pdf printer driver with minor customisation. All settings are maxed out. The background raster output in the pdf file is pixelated.
Oddly when printing sample (smaller area - A3 size) the output looks much better. Only when switching to whole sheet (custom paper size over A1 size)
the screen capture from sheet model view:
screenshot of corresponding area from pdf
pdf driver configuration:
It is rasterized (in other software) GIS map. Rasters are georeferenced and tiled. Stored locally.
I have uploaded sample dgn file with 1 raster file attached, sample pdf output file and pdf driver.
I am out of ideas how to fix it.
