vec2web is a dxf to png (and other format) convertor based on the QCAD libraries.

I downloaded and compiled it. However when I ran it the text dimensions were missing.

I discovered the reason for this is that vec2web needs to be able to find the fonts and resource in the QCAD directory. I copied the vec2web binary to the QCAD root directory. I then created this script to take the command arguments and then cd to the QCAD dir before running vec2web.

#!/bin/sh
# convert dxf's to png
# sample command:
# vec2web.sh input.dxf output.png 1024

DIR=`pwd`
QCAD=/usr/local/qcad-2.2.2.0-1-prof.linux.x86

if [ -z "$1" -o -z "$2" -o -z "$3" ] ; then
	echo $0 input.dxf output.png resolution
	exit 1
fi

X=$3
Y=$3

cd $QCAD

./vec2web $DIR/$1 $DIR/$2 -x $X -y $Y

The result after properly 'homing' vec2web so it can get to the QCAD fonts:
