canvas.showimage opens empty window on Mac OS Lion #314

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago
I just installed javaCV and OpenCV. I tried running one of the examples, 
related to Blob detections. The Program runs fine, I can get the values out on 
the console and save modified images, but the canvas.showimage call always 
opens an empty grey window. Even just loading and calling the showImage does 
not work.

Any thoughts?

Could you also try to run the Demo class in the README.txt file? Does the same 
thing happen?

actually yes, I just tried, is there a way to get you more information about 
that? Could be the environment not being set properly?

Hum, there may be a bug in Java on Mac I suppose. Does calling something like 
`canvas.setCanvasSize(100, 100)` do anything interesting?

I can confirm this as well. Shows a blank screen on Mavericks.

Does enabling/disabling any of these options change anything?
