|
|
|

|

|
|
|

|
|
|
| Tip: By double-clicking the Zoom Icon you can automatically zoom to 100%
|

|
| Pan
|
|
|
| The Pan tool is used to move the image once zoomed in. It is used by clicking at the image and dragging it to the position required.
|
|
|
| Using the Pan-Options you can type in exactly the location you want to centre the image about.
|
|
|

|
|
|
| Crop
|
|
|
| The crop tool can be used to specify the region of the image you wish to save. You define a region by clicking at the top left point of the region and dragging the mouse to the bottom right point.
|
|
|
| ToneUp will display the crop region by shading the area outside of the crop grey. The region will have small yellow crosses at each corner which can be used to adjust the region. Alternatively, you can pick up and move the crop region by clicking at the centre of the area.
|
|
|
| Right clicking at the image will access the options menu and allow you to cancel the current crop.
|
|
|
| The crop region can be 'nudged' one pixel at a time using the cursor keys. Holding Shift or Ctrl down at the same time allows you to adjust the top-left or bottom-right points.
|
|
|
| Pressing Enter (or double clicking) will zoom the crop region such that it fits the screen.
|
|
|
| Using the Crop-Options you can specify the exact aspect ratio of the crop. For example, typing 6 and 4 into the two boxes will constrain the crop region to 6 units wide and 4 units high. You can also select from a number of pre-defined crop sizes using the drop down menu.
|
|
|
| Tip: The crop is not a destructive tool, i.e. it only gets applied during the save process and can therefore be adjusted or removed at any time.
|
|
|
| Tip: Using the Opacity slider you can vary the strength of the grey region to help you view the crop.
|
|
|
| Tip: By double-clicking the Crop Icon you can fit the image window to the screen.
