-when importing an image on aligned world it is zoomed far in and should be centered

When I try to use keypoints to align my images, they don't display anymore in the main view.

Maybe I'm just missing some documentation on the workflow I should apply.

Hi,

Looking forward to a solution for installing PCBRE on Win7x64

Thanks.

Tool settings should be moved to the parameter window. Selecting an object should populate the parameter window with settings for that object.

Clicking the "apply" or "rollback" buttons should result in committing the edited object to the database.

1. Netlist export to KiCad
2. Undo/Redo components and traces in main window
3. GUI menu to reload project once saved
4. Opacity in the main window
5. Installer
6. Export gerbers
7. Remove an image once imported
8. Diagram explaining dimensions in the component dialog
9. ESC to exit tools
10. Use ctrl or shift to lock the trace into 90deg variants
11. Standard packages ie soic 8 etc for components
12. Transistor packages (TO20, SOT-23 etc)
13. Zoom slider to allow for user to change with mouse
14. Wizard for importing images and assigning to layers
15. Icon for PCBRE

The call to GLS.compileProgram() in PyOpenGL (called from https://github.com/davidcarne/pcbre/blob/master/pysrc/pcbre/ui/gl/shadercache.py#L69) in turn calls program.check_validate(). On OS X, this throws an exception if the OpenGL state isn't completely set up.

The proposed fix was to rework the code in https://github.com/davidcarne/pcbre/blob/master/pysrc/pcbre/ui/gl/shader.py to correctly use EnhShaderProgram. My temporary fix was to use the compileProgram function from that module, and wrapping the call to check_validate() in a try/except block.

After managing to install (see #1), pcbre starts but fails to display images, screen stays black.

The following backtrace may explain why :

Hello,
first, thank you for your presentation at Recon which was really cool. Also thanks for releasing this tool.

I am mainly opening this issue to document the problems that I have when trying to install pcbre on Debian sid :

• the readme does not clearly state that Python 3 is needed
• apt-get install libcapnp-dev python3-numpy python3-scipy libgeos-dev python3-mock python3-pyside cython3 libpotrace-dev libagg-dev cover most dependancies
• your fork of pypotrace where you changed "agg_pic" to "agg" in setup.py breaks compilation on Debian
• pycapnp doesn't find schema.capnp when installing, PYTHONPATH must be modified by hand
• opencv-2 doesn't have python3 bindings, one must install opencv-3 to have python3 bindings.

Once most libraries are installed : rtree and opengl module are missing, fix with :

apt install libspatialindex-dev
pip install rtree PyOpenGL

THEN pcbre starts :)

Note that python3-opengl from Debian does not work.

Steps to reproduce :

• add package on PCB
• zoom
• see pin numbers
• rotate
• pin numbers are not displayed

Hello,
how that #2 is fixed, I can add information to my layers but it seems vias don't work. Nothing shows up when I try to add one.

Maybe I'm missing something regarding layers ?

-looses focus on the main window after the tab dialog closes on component placement

once the resistor is paced the resistor cannot be selected hence cannot be deleted

Displayed/updated pin information seems to be aliased between multiple components.

reported by @mrhlogic

-text in dialog of component window about dimension 1 is along pin 1 edge is overflowing the dialog

Problem is similar to https://stackoverflow.com/questions/27721469/python-segmentation-fault-core-dumped (same backtrace)
