SVG Export broken when setting mode to polygon
technopagan opened this issue · 1 comments
It seems that SVG export is currently broken when applying the "-m 8" switch for polygon mode. PNGs render just fine, but when switching to SVG, the resulting XML is almost empty, aka no polygons are declared:
<svg xmlns="http://www.w3.org/2000/svg" version="1.1" width="680" height="1024">
<rect x="0" y="0" width="680" height="1024" fill="#797261" />
<g transform="scale(4.000000) translate(0.5 0.5)">
</g>
</svg>
Tested with "kodim19" test image (http://optipng.sourceforge.net/pngtech/corpus/kodak/kodim19.png) using the following switches: "primitive -i kodim19.png -o kodim19_primitive.svg -n 10 -m 8". My environment is WSL, Linux Subsystem for Windows, Ubuntu 16.04 based, Fish shell, Golang v. 1.7.4 installed via LinuxBrew)
As you can see, other simple SVG shapes export just fine. Here's an example with -m 0 (Mixed mode): "primitive -i kodim19.png -o kodim19_primitive.svg -n 10 -m 0". Notice how the lines in which polygons should have been declared stay empty:
<svg xmlns="http://www.w3.org/2000/svg" version="1.1" width="680" height="1024">
<rect x="0" y="0" width="680" height="1024" fill="#797261" />
<g transform="scale(4.000000) translate(0.5 0.5)">
