PCB tools extension

===
PCB tools extension is a Python library to panelize gerber files.
This library is designed based on [PCB tools](https://github.com/curtacircuitos/pcb-tools) which provides cool functionality to handle PCB such as generationg PCB image from gerber files.

### PCB Outline
You can also load a dxf file and handle that as same as RX-274x gerber file.<br>
This function is useful to generate outline data of pnanelized PCB boad.

### Mouse bites
<img alt="mouse bites" src="https://raw.githubusercontent.com/wiki/opiopan/pcb-tools-extension/images/mousebites.png" width=200 align="right">
If ```DM_MOUSE_BITES``` is specified for ```drawing_mode```, filled circles will arranged along a DXF line object at equal intervals. <br>
DXF file object in this state can be merged to excellon file also. That means you can arrange mouse bites easily.
```python
import gerberex
ctx = gerberex.DrillComposition()
drill = gerberex.read('drill.txt')
ctx.merge(drill)
dxf = gerberex.read('mousebites.dxf')
dxf.draw_mode = gerberex.DxfFile.DM_MOUSE_BITES
dxf.to_metric()
dxf.width = 0.5
dxf.pitch = 1
ctx.merge(dxf)
ctx.dump('merged_drill.txt')
```
