Edit Property Dialog

The Edit Property dialog provides basic editing control over the image appearance.  Controls are provided for image rotation, cropping, and contrast and brightness adjustment.  The illustration below shows a the Edit Property dialog

Cropping Tool

The selected slide is shown surrounded by an Area Selection Box with six "handles" shown as blue dots.   Holding the cursor over a dot and then holding down the right button and moving the mouse will resize the Area Selection Box, providing the desired cropping of the image.

The selected area of the image is when completed the selected area of the image is cropped to the contents of the Area Selection Box and then resized to full the slide frame.   This process may be undone by selecting the Undo on the Edit menu on the main taskbar.

The button to the right of the Crop Position Indicators will reset the Area Selection Box to the full image when clicked.  The Crop Position Indicators all show pixel values.

The Crop Tool provides two manual ways of cropping an image.  These are the Margin and Frame methods which are selected by the button below the Crop Position Indicators.

When Margin is selected exact cropping margins may be typed directly into the Crop Position Indicators which now show margin width.  The full image initially has no margins so all values are set to zero.  The Margin method is used when a known amount of border is desired to be removed from each side of the image.

The Frame method utilizes the absolute coordinates of the image.  Moving the Area Selection Box causes the values of the Crop Position Indicators to change as it is moved.  Cropping may be accomplished in using either method or by interactively adjusting the Area Selection Box.

Rotation Tool

Below the Crop tool area are two curving arrows.  These arrows will rotate the selected image 90 degrees in the direction indicated by the arrow.  This function is especially useful when dealing with images input directly from a digital camera medium which may be in both vertical and horizontal rotations depending how the camera was held when the images where acquired.

Brightness and Contrast Adjustment

To the right of the Rotation tool are the Brightness and Contrast control tools. Moving the Brightness Control to the right will increase the brightness of the image while moving to the left will darken the image.  The contrast Control operates in a similar manner with movement to the right increasing the contrast and moving to the left decreasing it.

Apply To:

The Apply To controls will apply changes indicated by the Rotate and Brightness and Contrast controls to the selected groups but will not apply any cropping except to the current slide.
