Fix autozoom mode

[dy]

Now autozoom resets every time next/prev image is clicked:


Which makes jagged slideshow experience in fullscreen. Is there a way to force zoom level for all images?

this never gonna be fixed?

I might be missing something, but passing auto instead of 100% in the first else in CheckAutoZoomNeeded makes it auto-zoom new images by default:

	private void CheckAutoZoomNeeded()
	{
		if (originalImage != null)
		{
			if (!fullscreen && (originalImage.Width < picturePanel.Width - 32) && (originalImage.Height < picturePanel.Height - 32))
			{
				if (zoomTextBox.Text == "100%") setZoomFactor(100);
				else setZoomText(LangMan.Get("auto")); // was setZoomFactor(100);
			}
			else
			{
				setZoomText(LangMan.Get("auto"));
			}
		}
		else
		{
			setZoomText(LangMan.Get("auto"));
		}
	}

Seems like a typo to me, because the if doesn't really make sense, if you set 100% in the else, too.

I'd also simplify the method to something like this:

    private void CheckAutoZoomNeeded()
    {
        if (originalImage != null && !fullscreen && originalImage.Width < picturePanel.Width - 32 && originalImage.Height < picturePanel.Height - 32 && zoomTextBox.Text == "100%")
            setZoomFactor( 100 );
        else
            setZoomText( LangMan.Get( "auto" ) );
    }

No need for three else with the same body.
