将Eagle原理图或电路板导出到图像或部件列表
eagexp的Python项目详细描述
eagexp可以导出原理图或电路板的eagle部件列表或图像（2D/3D）
- 链接：
- 功能：
- 用python编写
- 它可以用作库或命令行程序
- 后台处理（仅当安装了Xvfb和pyvirtualdisplay时）
- 超时
- 使用eagle3d和povray导出三维图像
- 计算电线
- 已知问题：
- 慢：每一个出口都要打开和关闭eagle
- 高dpi不起作用（内存问题？）
- Eagle可以阻止导出->；超时
- 3D图像导出有许多不受支持的选项
基本用法
>>> from eagexp import image, partlist >>> brd='~/.eagle/projects/examples/singlesided/singlesided.brd' >>> image.export_image(brd, 'brd.png', resolution=600) >>> print partlist.raw_partlist(brd)
工作原理
- 使用pyvirtualdisplay
- 通过设置$display变量，将eagle display重定向到Xvfb服务器
- 使用export和quit命令启动eagle
安装
一般
ubuntu 14.04
sudo apt-get install python-pip eagle povray python-pil xvfb xdotool sudo pip install eagexp
卸载
# as root pip uninstall eagexp
用法
从python代码导出
示例：
#-- include('examples/image_example.py')--#
'''
Example for image export with various options
'''
from eagexp import image
brd = '/usr/share/eagle/projects/examples/tutorial/demo2.brd'
if __name__ == "__main__":
# set resolution in DPI
image.export_image(brd, 'api_brd_50.png', resolution=50)
image.export_image(brd, 'api_brd_100.png', resolution=100)
image.export_image(brd, 'api_brd_150.png', resolution=150)
# mirror image
image.export_image(brd, 'api_brd_mirror.png', mirror=True)
# display only 2 layers
image.export_image(brd, 'api_brd_layer.png', layers=['dimension', 'pads'])
# display layer using eagle command
image.export_image(
brd, 'api_brd_command.png', command='display none dimension')

input output
Exporting eagle .sch or .brd file into image file. GUI is not displayed if
``pyvirtualdisplay`` is installed. If export is blocked somehow (e.g. popup
window is displayed) then after timeout operation is canceled with exception.
Problem can be investigated by setting 'showgui' flag.
Exporting generates an image file with a format corresponding to the given
filename extension. The following image formats are available:
.bmp Windows Bitmap Files
.png Portable Network Graphics Files
.pbm Portable Bitmap Files
.pgm Portable Grayscale Bitmap Files
.ppm Portable Pixelmap Files
.tif TIFF Files
.xbm X Bitmap Files
.xpm X Pixmap Files
positional arguments:
input eagle .sch or .brd file name
output image file name, existing file will be removed first!
optional arguments:
-h, --help show this help message and exit
-t TIMEOUT, --timeout TIMEOUT
operation is canceled after this timeout (sec)
-p PALETTE, --palette PALETTE
background color [None,black,white,colored]
-r RESOLUTION, --resolution RESOLUTION
image resolution in dpi (50..2400)
-l LAYERS, --layers LAYERS
list, layers to be displayed ['top','pads']
