Hi list, While attempting to fix https://github.com/qgis/QGIS/issues/33465 I'm running into some confusion about the meaning of pdfCoordinateType values in GeoPDF composition.xml files.
The example composition.xml from https://gdal.org/drivers/raster/pdf.html includes: <Page id="page_1"> <DPI>72</DPI> <Width>10</Width> <Height>15</Height> .... This would suggest to me that the Width and Height (and accordingly all pdfCoordinateType) values are in inches. But that doesn't match with the actual behavior I'm seeing, where it seems like Width/Height and other pdfCoordinateType values need to be specific in pixels (i.e. size in inches * dpi). Actually it's a bit more complex than this, because regardless of the DPI specified for the page, the width/height have to be specified in size in inches * 72! (i.e. there's a hardcoded 72 dpi assumption somewhere). Can anyone clarify exactly how PDF coordinates and sizes should be calculated in composition.xml? Thanks!
