Zoom
figure 1: The Zoom Button
The Zoom control allows you to zoom into any portion of the picture displayed in the Preview/Adjust Monitor. To activate this feature, click the Zoom button. This will cause Snappy to highlight the Zoom button which informs you that Zoom mode is active. Clicking it again will turn off the Zoom feature and un-highlight the Zoom button.
Zoom is very useful when you are making changes to the Adjust controls (Sharpness, for example), so that you can get a closer look at the changes you make before hitting the Process button.
While zooming, if you click and hold the left mouse button in the Preview/Adjust Monitor, and move the pointer to one of the edges of the window, you can get to the exact portion of the picture you are concerned with. Once you have finished making adjustments to the picture as normal, you can see the results by clicking the Process button. Note that Zoom has no effect over the final picture size, it is only a tool for helping you while you make adjustments.
