Sorry for the bother again - I noticed that when I use gdalinfo to query a document (in this case, a GeoPDF) the geotransform coordinates are slightly different than when I can GetGeoTransform using the API on the same document with GDALOpen + GDALGetGeoTransform.
Presumably due to a difference in number of significant digits displayed in both cases.
But I also noticed the WKS seems to be different in the two as well. Is there a configuration or something else I might be missing that would cause these to be off?
gdalinfo uses WKT_2:2019, and GetProjectionRef() uses WKT1. You can use GetSpatialRef()->exportToWKT(apszOptions) with apsOptions = { "FORMAT=WKT2_2019", nulptr } to get the same result
