0.84: Always high quality zoom when zooming out

Post by helmut »

XnView: MP 0.84
OS: Windows 10 - 64bit

When deactivating high quality zoom for Viewer, high quality is still applied when zooming out (small zoom factor, e.g. 10 %). This can be clearly seen when viewing black/white images.

Effect: Irritating user interface (minor)

To reproduce:
1. Set High zoom quality to "Never" in Settings » View | View
1. Open a colour image with medium size (1000 x 1000 pixel)
2. Convert the image to black/white image using:
a. Select Image » Change colour depth"
b. In "Change color depth" dialog select (o) Binary and Dithering: Floyd Steinbarg
c. Confirm with "OK" button
3. Zoom out the image using the mouse wheel (small zoom factor, e.g. 10%)
Actual behaviour (bug): The image is displayed in reasonable (high) quality.

Expected behaviour: The image is displayed in bad (low) quality and should look very pixelated due to the dithering.
