Description Ray Johnston 2011-02-05 05:58:17 UTC
Created attachment 7201 [details]
0808.pdf

The fts_08_0808.pdf from the PDF_1.7_FTS Quality Logic Suite shows a clipped
"stroke" in clist mode with the following command line:

gswin32c -r600 -dBandHeight=128 -sDEVICE=ppmraw -o 0808.ppm fts_08_0808.pdf

The clipping is visible at the bottom of the really wide magenta stroke that
goes up and to the left at the center of the image.

The attached 0808.pdf subset shows this as well.

Clipping occurs at the top and bottom with -dBandHeight=64

Apparently the path for the stroke is not being written to enough clist bands
when the width is extremely wide (in this example "50 w" is in the PDF).

In the attached subset, I changed the stroke width to 90 to exacerbate the
problem.
