[Veusz-discuss] Displaying images

[Fred Labrosse]

All,

I guess this is a stupid question, but...

I'm trying to display images with a y axis going vertically down since
pixel (0,0) is at the top left. I can invert the loading of the data for
the image to be displayed correctly, but I can't make the y axis display
the values correctly (0 at the top, positive going down).

Any idea?

Cheers,

Fred

You can invert the direction of the axis by manually entering a minimum
which is greater than the maximum. Alternatively you can swap the
minimum and maximum axis position settings to reverse the direction
(0->1 to 1->0).

That and reversing rows worked. Thanks.
