Change to fit-to-window zoom doesn't work if current zoom is smaller

[Khairuddin Ni'am]

1. Open an image.
2. Select zoom scale that is smaller than fit-to-window zoom
3. Try change zoom level to fit-to-window zoom

Image won't scale up to fit-to-window zoom scale and zoom text changed to 100%.

It only work if current zoom level is larger enough than fit-to-window zoom.

I think the main point is to give you the maximum zoom when your image is too big for the window. I don't know if it matters when your image is small enough to fit in the window.

Paint.Net zooms to 100%
GIMP and Photoshop zoom to greater than 100%.

I don't really have a preference.

Maybe I didn't explain it properly.

What i mean is the odd behavior of "window" zoom, not the behavior after Pinta create or open an image.

1. Let say I create a new image that is larger than pinta's window. For example I create a new image with size 3000 x 3000

2. After I click OK, Pinta will scaled down the canvas to fit the window because the actual size larger than the window itself. On my computer, the image scaled down to 19%. So, my current zoom scale is 19%.

3. If I select "window" from zoom drop down menu, I expect my image will be scaled to fit the window. Because my current zoom scale is already fit to window, I expect it won't change anything if I select "window" zoom.
What actually happens is my image is scaled up to it's original size, 100%. On this case, "window" zoom's behavior is odd.

4. After step 3, my current zoom scale is 100%. Now, if I select "window" zoom again, Pinta will scaled down my image to fit the window, that is 19%. On this case, "window" zoom is acting properly.

Note : I prefer Paint.Net behavior than GIMP or Photoshop when open or create an image. Show it's original size if it smaller than window, otherwise scaled down to fit the window.

Strange... I have tested the above steps on Pinta0.5 on Windows XP.
1. I created new 3000 x 3000 image
2. Pinta scaled down to 20% in my case
3. I selected "Window" from drop down menu and NOTHING happens.
I have selected several zoom-drop-down options and then after that selected "Window" zoom option from drop-down window. "Window" option does not get any effect in my case. It just looks like having no action is executed for Window.

So I can't confirm exact behavior like yours, but I can confirm that "Window" options is probably broken.

Fixed in https://github.com/jpobst/Pinta/commit/3448d72143ca90e5cc21df6cfd2fe4b5345b1830.

Thanks for the report!

Strange... I have tried to reproduce comment #3 but now Pinta 0.7 behaves like this:
Note: On Windows I use 1024x768 screen resolution.
1. I created new 3000 x 3000 pixel image
2. Pinta scaled down to 20%
3. Zoom to 3600%
4. Back to Zoom = Window and Pinta zooms to 19%
5. Select one more time Zoom = Window and Pinta zooms to 20%.

Interesting that sometimes it selects 19% and sometimes 20%.

Ah... I have selected "Fix Released" by mistake. I should select "New", but now I can set it to new anymore. Can you please change the status back to new.

[Jonathan Pobst (jpobst)]

What are saying is still broken on this? That it sometimes picks 19% and sometimes picks 20%?

My guess is that is caused by whether there are scrollbars visible or not, as the affects the window size.
