Photo viewer is still in Windows 10, as it is in 8.1. You can use the mouse wheel to zoom in and out and arrow keys to navigate photos in the same folder. Computer Type: PC/Desktop.

How to make scroll wheel zoom work in Windows 10 with Creo Parametric I had a very difficult time finding a solution for this. If you are having trouble zooming in Creo with mouse wheel go to control panelhardware soundmouse and click on the 'Wheel' tab and set the option in the vertical scrolling area 'one screen at a time' this solved.

Windows Photo Viewer isn't part of Windows 10, but if you upgraded from Windows 7 or Windows 8.1, you might still have it. To check, press and hold (or right-click) a photo in File Explorer, and select Open with. If Windows Photo Viewer isn't in the list, you cannot install it on Windows 10.

The Photos app in Windows 10 does the same things Photo Viewer did, and more..

The Photos app in Windows 10 allowed users to go to the next or previous photo by scrolling the mouse wheel. Users were not happy with this functionality. It was likely due to Windows Photo Viewer, the default photo viewing app in Windows 7 which allowed users to zoom in/out with the scroll wheel.
In most cases you zoom by holding down the CTRL button aswell. Have you tried that (I'm still on Anniversary so I can't verify how it is on Creators). Edit: I just updated the Photo app, and now I also get this 'bug'. Sadly, this is how most Photo apps and programs I have used before have worked.

Press Ctrl + the mouse wheel to zoom in or out. Change mouse wheel settings in More> Settings.
To browse photos within a folder, open a photo from the Folders view or File Explorer, then swipe right or use the arrow keys to see the next item.
Click on a photo to show the buttons at the top, including Zoom, Delete, Rotate, Edit & Create, Share, and Print. Press and hold (or right-click) for more commands, such as File info, Save as, Copy, and Set as.

Creating a scrollable and zoomable image viewer in C# Part 4

In the conclusion to our series on building a scrollable and zoomable image viewer, we'll add support for zooming, auto centering, size to fit and some display optimizations and enhancements.

Unlike parts 2 and 3, we're actually adding quite a lot of new functionality, some of it more complicated than others.

First, we're going to remove the ShowGrid property. This originally was a simple on/off flag, but we want more control this time.

We've also got a number of new properties and backing events to add:

AutoCenter - controls if the image is automatically centered in the display area if the image isn't scrolled.
SizeToFit - if this property is set, the image will automatically zoom to the maximum size for displaying the entire image.
GridDisplayMode - this property, which replaces ShowGrid will determine how the background grid is to be drawn.
InterpolationMode - determines how the zoomed image will be rendered.
Zoom - allows you to specify the zoom level.
ZoomIncrement - specifies how much the zoom is increased or decreased using the scroll wheel.
ZoomFactor - this protected property returns the current zoom as used internally for scaling.
ScaledImageWidth and ScaledImageHeight - these protected properties return the size of the image adjusted for the current zoom.

Usually the properties are simple assignments, which compare the values before assignment and raise an event. The zoom property is slightly different as it will ensure that the new value fits within a given range before setting it.

Using the MinZoom and MaxZoom constants we are specifying a minimum value of 10% and a maximum of 3500%. The values you are assign are more or less down to your own personal preferences - I don't have any indications of what a 'best' maximum value would be.

Setting the SizeToFit property should disable the AutoPan property and vice versa.

Several parts of the component work from the image size, however as these now need to account for any zoom level, all such calls now use the ScaledImageWidth and ScaledImageHeight properties.

The AdjustLayout method which determines the appropriate course of action when certain properties are changed has been updated to support the size to fit functionality by calling the new ZoomToFit method.

Due to the additional complexity in positioning and sizing, we're also adding functions to return the different regions in use by the control.

GetImageViewPort - returns a rectangle representing the size of the drawn image.
GetInsideViewPort - returns a rectangle representing the client area of the control, offset by the current border style, and optionally padding.
GetSourceImageRegion - returns a rectangle representing the area of the source image that will be drawn onto the control.

The sample project has been updated to be able to display the results of the GetImageViewPort and GetSourceImageRegion functions.

As with the previous versions, the control is drawn by overriding OnPaint, this time we are not using clip regions or drawing the entire image even if only a portion of it is visible.

Depending on the value of the GridDisplayMode property, the background tile grid will either not be displayed, will be displayed to fill the client area of the control, or new for this update, to only fill the area behind the image. The remainder of the control is filled with the background color.

Previous versions of the control drew the entire image using the DrawImageUnscaled method of the Graphics object. In this final version, we're going to be a little more intelligent and only draw the visible area, removing the need for the previous clip region. The InterpolationMode is used to determine how the image is drawn when it is zoomed in or out.

With the control now all set up and fully supporting zoom, it's time to allow the end user to be able to change the zoom.

The first step is to disable the ability to double click the control, by modifying the control styles in the constructor.

We're going to allow the zoom to be changed two ways - by either scrolling the mouse wheel, or left/right clicking the control.

By overriding OnMouseWheel, we can be notified when the user spins the wheel, and in which direction. We then adjust the zoom using the value of the ZoomIncrement property. If a modifier key such as Shift or Control is pressed, then we'll modify the zoom by five times the increment.

Normally, whenever we override a method, we always call it's base implementation. However, in this case we will not; the ScrollbableControl that we inherit from uses the mouse wheel to scroll the viewport and there doesn't seem to be a way to disable this undesirable behaviour.

As we also want to allow the user to be able to click the control with the left mouse button to zoom in, and either the right mouse button or left button holding a modifier key to zoom out, we'll also override OnMouseClick.

Unlike with the mouse wheel and it's fixed increment, we want to use a different approach with clicking. If zooming out and the percentage is more than 100, then the zoom level will be set to the current zoom level + 100, but rounded to the nearest 100, and the same in reverse for zooming in.

If the current zoom is less than 100, then the new value will +- 75% of the current zoom, or reset to 100 if the new value falls between 75 and 125.

This results in a nicer zoom experience then just using a fixed value.

You can download the final sample project from the link below.

What's next?

One of the really annoying issues with this control that has plagued me during writing this series is scrolling the component. During scrolling there is an annoying flicker as the original contents are moved, then the new contents are drawn. At present I don't have a solution for this, I've tried overriding various WM_* messages
