[Gambas-user] Image smoothing

[juan duque]

Obviously my English is somewhat lacking. Apologies.

I think this is not a bug but rather a design with some shortcomings.

Smoothing (or interpolation) of an image is often convenient but not
desirable in all cases.
Attached a sample program (this would be a magnifying glass).

Is there any way of disable smoothing in the image/paint/draw component?

Regards
