<p>Carl,</p>
<p>I don't have one such PDF at hand, but with one sample of the
GDAL autotest suite:</p>
<p>$ gdalinfo autotest/gdrivers/data/pdf/adobe_style_geospatial.pdf
-mdd LAYERS<br>
[...]<br>
Metadata (LAYERS):<br>
LAYER_00_NAME=New_Data_Frame<br>
LAYER_01_NAME=New_Data_Frame.Graticule<br>
LAYER_02_NAME=Layers<br>
LAYER_03_NAME=Layers.Measured_Grid<br>
LAYER_04_NAME=Layers.Graticule<br>
[...]</p>
<p>Programatically, you can get this list of layers with
Dataset.GetMetadata("LAYERS")</p>
<p>Then you can select layers you want to activate with the LAYERS
open option:</p>
<p>gdal_translate
autotest/gdrivers/data/pdf/adobe_style_geospatial.pdf out.tif -oo
LAYERS=New_Data_Frame.Graticule,Layers.Graticule</p>
<p>or disable select ones with the LAYERS_OFF open option:</p>
<p>gdal_translate
autotest/gdrivers/data/pdf/adobe_style_geospatial.pdf out.tif -oo
LAYERS_OFF=New_Data_Frame.Graticule,Layers.Graticule</p>
<p>Programatically,</p>
<p>gdal.Translate("out.tif", gdal.OpenEx("in.pdf", open_options = ["LAYERS=New_Data_Frame.Graticule,Layers.Graticule"])</p>
<p>Even<br>
