This is great -- our backend _driver is a poor man's unit test, but it has served us well and it's good to make the most of it. I've added a cohere_demo.py and added it to backend_driver. > > python agg_resize.py > Traceback (most recent call last): > File "agg_resize.py", line 7, in <module> > interp = agg.span_interpolator_linear(imMatrix); > AttributeError: 'module' object has no attribute 'span_interpolator_linear' Hmm, for some reason the following lines are commented out of swig.agg.i //%include "agg_span_interpolator_linear.h" //%template(span_interpolator_linear_affine) agg::span_interpolator_linear<agg::trans_affine>; //%include "agg_span_image_filter.i" I think I am the only one who has worked on this part of the code, so I must have done it but don't know why. This is a low priority bug since we are not using the low level agg renderer for much (it was written to try and decrease reliance and ultimately drop the CXX) but the endeavor has languished. I'll need to spend some time to figure out why this is commented out and if it can be restored. > > python embedding_in_wx2.py > [The y-axis labels are being cut off at the bottom of the figure.] This is a pretty low priority since I am already somewhat inclined to drop pure wx rendering. > > python image_slices_viewer.py > [It says the "use the scroll wheen to navigate images" [sic], but the > scroll wheel doesn't appear to do anything in TkAgg on Linux.] This works in gtkagg -- some tk users/developer/advocate needs to add support for the 'scroll_event'. I consider this to be fairly high priority and an easy fix. > > python keypress_demo.py > [Pressing "g" to toggle the grid causes the grid to flash momentarily > and then disappear again.] Fixed - this was written a long time ago before toggling the grid with 'g' was made the default. So this example simply toggled it on and off since two event handlers were being triggered.
