Global Mapper v25.0

Raster from PDF looks interpolated

I've turned off all the interpolation and antialiasing in the configuration-general-raster format menu but still have intermediate shades around linework when importing USGS topographic maps. It makes the resulting image have artifacts when used as a base for a geological map.

Is there a way to have sharp pixel edges when importing a PDF? If so, what settings do I need to change?

    I have added a new option to the Global Mapper v24.0.1 PDF import to allow disabling anti-aliasing of vector features. If you get the v24.0 daily build from https://www.bluemarblegeo.com/products/global-mapper-daily-builds.php tomorrow, then load with the 'Use faster draw engine' and 'Disable smoothing of vector features' options checked, then you should get solid colors.

    Thanks,
