Easy. There's some good examples of how to call out to VIGRA in edgedetect.hpp. I've committed this in CVS on the gamera3 branch. I haven't done much ...
I've added it to Gamera 2.x as well. However, there's lots of good stuff in Gamera 3.x and it seems to have reached pretty good stability on the tests at this...
Hallo, while analyzing a pile of CCs, I would like to assign each CC new properties (eg. a orientation_angle). On the python side, I can simply do an...
Hallo, just observed the following unexpected (to me) behaviour of draw_filled_rect: When the northwest and southeast pixel are the same, draw_filled_rect does...
... As a workaround I have written a C++ function that returns all properties in a PyList and a wrapper function that copies values from this list to image...
... I don't know of a much better way. When you get the underlying C++ image object from a Python object, the Python "box" around it is essentially discarded,...
It seems to be an unintentional consequence of the clipping that goes on (to make sure it doesn't write outside of the image.) Changing it to as you describe...
Hallo Michael, just needed to add two draw routines for operations in different metric spaces: draw_circle (constant boundary distance in euclidean norm) and...
... Thanks. I think that will be useful for a lot of things. ... Seems reasonable. I hesitate, though, because I have never seen anything else that works...
On Fri, 15 Jul 2005 08:21:19 -0400 ... A typical application of the draw_* functions is for visualization. I have noticed that the single pixel wide border...
... I agree that thickness is a nice thing to have. I'm only concerned about the interface. Looking at: draw_rect(ul, lr, color, thickness) the user may...
One other comment -- I notice in your docs that When the circle extends beyond the image border, the radius is silently reduced so that the circle fits within...
On Fri, 15 Jul 2005 08:33:17 -0400 ... I did not use this interface because when when filled=True the parameter thickness were meaningless. ... There is...
On Fri, 15 Jul 2005 08:41:28 -0400 ... Yes. It was only my laziness and performance considerations that let me avoid the plausi checks for ncols/nrows > x/y >=...
... Ah, I get it now. In some ways, I like this approach vs. the "standard" PostScript way of centering the thickness around the virtual circle, since it...
... I understand. You could still avoid checking at every pixel, however... 1. When the circle is filled, by clamping the range of the column iterator, or not...
On Thu, 14 Jul 2005 11:46:59 +0200 ... Just observed another (possibly related) oddity with draw_filled_rect: the input argument for the lower right corner...
... No, but I believe it is part of the same error -- its really just a < vs <= issue. I think I'll go ahead and change it, since I've heard no complaints. ...
I've Cc'd the list, because I think this will be generally useful. ... Yes. Absolutely right. ... Copy the Cc's to regular onebit images first. This means they...
Hi, A problem in rotate() is detected. Problem Description: a.. When rotation angle is below a degree of -45.0 or above 225.0, rotation will generate a...

Hi all, I am running the CVS from 2005-07-22 on Kubuntu Hoary against wxWindows 2.4.2 I believe When I run the interactive classifier and go to classify a new...
Ah ok.... I remember now, people told me earlier on this list about the selection being a little funky in wxwindows for that grid. I hit Ctrl while clicking...
Thanks. The funky thing about the grid widget is that you have to select by crossing the center of the box -- so mouse down of the left side, drag to the...
Hello, First, let me introduce myself. I'm a new student of Ichiro Fujinaga's at McGill. I'll be working on Gamera, and so expect to hear from me again from ...
The unit testing and documentation examples are one-and-the-same with plugin functions (though I realise that's not entirely clear from the docs, in...
There is now very brief documentation about unit testing with Gamera here: http://dkc.jhu.edu/gamera/html/unit_testing.html Comments and feedback encouraged. ...
Hallo, just saw in the online docs that new thinning methods have been added. However after checking out from cvs, removing my previous gamera install and...
