General Options

Mouse Options

These are the options that allow you to zoom in and out on images using the a mouse button and scroll wheel. Right click on an image and keep the right mouse button pressed while using the scroll wheel to zoom in and out.

Use Mouse Functions: Use this check box to enable/disable the use of image zoom mouse functions in your browser

Access Mouse Button: This dropdown box has three options, left, middle and right (default). This value controls which mouse button is used to gain access to the mouse functions by pressing and holding the defined button over an image in your browser.

Options Dialog

Image Fit Button: This dropdown box has three options, left (default), middle and right. This value controls which mouse button is used to execute the image fit function.

Toggle Image Fit/Reset Checkbox: This checkbox will enable the toggling of Image Fit/Reset for the Image Fit Mouse Button. This means that if the image you are executing this function on has already been fitted, then this function will perform an image reset and vice versa.

Image Reset Button: This dropdown box has three options, left, middle (default) and right. This value controls which mouse button is used to execute the image reset function.

Scroll Zoom Increments: You can control by how much each increment of the scroll wheel zooms an image. For example, a value of 5 here will increase the size of an image by 5% for each increment of the scroll wheel.

Reverse Scroll Checkbox: This checkbox will reverse the default direction of the scroll wheel for zooming in and out.

Scroll Mode: This dropdown box has two options, relative (default) and absolute. Relative scroll mode increases or decreases the size of the image by a percentage of the current image size. eg if the image is currently zoomed to 200% and the scroll zoom increment is set to 5%, one increment on the scroll wheel will zoom the image to 210%. Absolute scroll mode increases or decreases the size of the image by a percentage of the original image size. eg if the image is currently zoomed to 200% and the scroll zoom increment is set to 5%, one increment on the scroll wheel will zoom the image to 205%.

Individual Zoom Options

Zoom In/Out Factor: is the factor used to zoom images when selecting the "Zoom In" functions or the "Zoom Out" functions.

The formula's used are demonstrated below:
Zoom In NewSize = ("Zoom Factor" * "Image Size") / 100
Zoom Out NewSize = "Image Size" * (100/"Zoom Factor")

For example, a value of 200% here will double the size of an image when zooming in, and halve the size of an image when zooming out.

Auto Center Images when using Image Fit: will automatically scroll the browser window to make the image in the center of the screen when using the "Image Fit" function.

Zoom Context Menu Item Options

Options Dialog

These are the menu items for zooming that you wish to display on the main context menu when you right click on an image on a web page. You may want to put regularly used functions on the main context menu for convenience or, on the other hand, you may want to have nothing on the main context menu to avoid User Interface Clutter. For descriptions on how the different functions work refer to the "Functions" section below.

To enable or disable context menu items simply use the check boxes next to each context menu item on the options screen

Functions

Function Name Description
Zoom In Increase the size of the selected image by the factor used in the "Zoom In/Out Factor" option
Zoom Out Decrease the size of the selected image by the factor used in the "Zoom In/Out Factor" option
Zoom Reset Reset the size of the image to the size it was when the page first loaded
Custom Zoom Show a dialog allowing you to enter any zoom value for the image. The image will be zoomed to the value that you enter based on the original Image Size. For example, if you put 150%, the image will be zoomed to 150% of the original size
Custom Dimension Allows you to enter any width and height that you would like the image to be in pixels. "Maintain Aspect Ratio" will force the dimensions to remain in their original proportions
Image Fit Attempt to resize the image to fill as much of the browser window as possible. When the "Auto Center Images when using Image Fit" option is turned on, the window will also scroll to center the image in the browser
400%; 200%; 150%; 125%; 100%; 75%; 50%; 25%; 10%; Zooms the image to the selected percentage value of the original image size
