Wrong text size when converting DXF to PDF

[Alan Thomas]

I converted autotest/ogr/data/leader-mleader.dxf to PDF using ogr2ogr:

ogr2ogr -overwrite -f "PDF" leader-mleader.pdf "C:\Projects\gdal\autotest\ogr\data\leader-mleader.dxf" -dsco STREAM_COMPRESS=NONE

The text sizes in the resulting PDF are excessively large.

Here's an example style string from ogrinfo -al on the original DXF (this is the style string for the big red text you see in the page):

LABEL(f:"Arial",t:"Apples",p:2,s:1g,c:#ff0000,a:10)

The font size in the resulting PDF is 1000.000000. Looking through the code, it's unclear to me where the multiplication by 1000 is taking place. I'm not sure what the correct size is; the text should be 1 DXF unit high, as implied by the style string, but a value of 1.0 in the PDF is too small.

(As a side note, each text object is associated with a grey circle, which seems unwanted.)
