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：

TravisCoverallsLatest VersionSupported Python versionsLicenseDownloadsCode HealthDocumentation

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

  1. 使用pyvirtualdisplay
  2. 通过设置$display变量，将eagle display重定向到Xvfb服务器
  3. 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')
#-#

启动示例程序：

python -m eagexp.examples.image_example

结果：

3d示例：

#-- include('examples/image3d_example.py')--#
'''
Example for 3D image export
'''
from eagexp import image3d

brd = '/usr/share/eagle/projects/examples/tutorial/demo2.brd'

if __name__ == "__main__":

    # size
    image3d.export_image3d(brd, 'api_3d_size1.png', size=(50, 50))
    image3d.export_image3d(brd, 'api_3d_size2.png', size=(50, 100))
    image3d.export_image3d(brd, 'api_3d_size3.png', size=(100, 50))

    # rotate
    image3d.export_image3d(
        brd, 'api_3d_xrot.png', pcb_rotate=(180, 0, 0), size=(200, 150))
    image3d.export_image3d(
        brd, 'api_3d_yrot1.png', pcb_rotate=(0, 45, 0), size=(200, 150))
    image3d.export_image3d(
        brd, 'api_3d_yrot2.png', pcb_rotate=(0, 90, 0), size=(200, 150))
    image3d.export_image3d(
        brd, 'api_3d_yrot3.png', pcb_rotate=(0, 135, 0), size=(200, 150))
#-#

启动示例程序：

python -m eagexp.examples.image3d_example

结果：

_img/api_3d.png_img/api_3d_xrot.png_img/api_3d_yrot1.png_img/api_3d_yrot2.png_img/api_3d_yrot3.png_img/api_3d_size1.png_img/api_3d_size2.png_img/api_3d_size3.png

                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

                  input output

Exporting eagle .brd file into 3D image file using Eagle3D and povray. 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.

  output                image file name (.png)

optional arguments:
  -h, --help            show this help message and exit
  -s SIZE, --size SIZE  tuple(width, size), image size
  -p PCB_ROTATE, --pcb-rotate PCB_ROTATE
  -t TIMEOUT, --timeout TIMEOUT
                        operation is canceled after this timeout (sec)
  --showgui             eagle GUI is displayed
  --debug               set logging level to DEBUG
  --version             show program's version number and exit
