I have a collection of as built drawings stored as PDF’s and wanted to automate the creation of image files being used as thumbnails in a web application. I was wondering if anyone has done this before. I am currently using the Workbench 2018 PDF reader and attempting to rasterize using either ImageRasterizer or MapnikRasterizer.

Hi @lopes8
You can enable Read Rasterized Page parameter (Non-Spatial section) of the PDF reader parameters dialog which will render an image of each page and produce it as a raster feature (documentation here). You should be able to skip the ImageRasterizer or MapnikRasterizer if you use this parameter.
I hope this helps.

Hello,
I continue to have trouble converting PDFs to JPGs! I have followed the instruction above but still get error on the writer.
JPEG writer: This format cannot support more than 3 bands. Please remove the extra bands and try again
JPEG writer: An error has occurred. Check the logfile above for details
How do I find out the number of Bands as they pertain to ImageRasterizer’s Raster Properties Number of Columns and Number of Rows?? Or is there another way??
Thx
Brian
