The Image Settings dialog box allows you to define the initial display for the following groupings of image types: Bitonal, Color/Grayscale, PDF, and CAD. You can select the settings for each of the types: Initial Display, Rotation, Mirror, Image Enhancements, Scaling, Image Centering Coordinates, and Rectangle Coordinates.

To customize the Image Settings, select the Edit Parameters feature which is described below.

Edit Parameters

1. Click Edit Parameters to display the Image Settings dialog box.
2. Make the selections you want for the Image Types and their associated settings. For more information on the settings available, refer to the Detailed Information section below.
3. To save your selections, click OK. To cancel your selections, click Cancel. To restore the default setting, click Restore Defaults.

To save changes to the .ini file, you must click on the Save button on the Main menu before exiting the application.

Detailed Information

Select the desired default settings to associate with each grouping:

• Initial Display - Select your preferred viewing default setting.
• Rotation - Select your preferred default rotation. Rotation is applied counter-clockwise.
• Mirror - You can set the default to not mirror by not selecting anything, or mirror the image vertically and/or horizontally.
• Image Enhancements - In some situations (for example, scans of microfiche) you may want to set the default invert images. Use preserve lines to improve display of fine lines.
• Scaling - You can set defaults for applying scaling to viewed images. The default is Full Width for Bitonal and PDF images, and Zoom to Fit for Color/Grayscale and CAD images.
  • If Factor is selected, the default is 1.0, which is actual size. It can be adjusted from .01 to 10.
  • If Ratio is selected, the default is 1.0. Prizm Viewer sets the scaling from image pixels to screen pixels using this property.
  • Prizm Viewer will keep ImageScalingFactor and ImageScalingRatio in sync, but cannot keep InitialImageScalingFactor and InitialImageScalingRatio in sync. You should not set both InitialImageScalingFactor and InitialImageScalingRatio properties.
  • Image Centering Coordinates  can be updated if you have selected either “Factor and Location” or “Ratio and Location” in the scaling method.  These are image coordinates you specify as the center of the image. 
  • Rectangle Coordinates can be updated if you have selected either “Factor and Location” or “Ratio and Location” in the scaling method. This setting allows Prizm Viewer to set the initial position of the image by specifying image rectangle coordinates. The four values correspond to left, top, width, and height.

For PDF and CAD images, InitialImageScalingRatio and InitialImageScalingFactor have the identical effect. This is due to the fact that PDF and CAD images are not based on pixels. CAD images will generally not be displayed actual size unless the size unit for the CAD image is inches. All other units will be treated as inches and scaled accordingly. For example, a CAD image measured in miles will be displayed 1 inch per mile if you set this property to 1.0.

• Brightness - This setting applies only to color images and tells Prizm Viewer to set image brightness when the image first displays. The default value is 0. The range of values is -100 to 100.

This setting does not apply to bitonal, PDF, and CAD images.

• Contrast - Setting that allows the application to set image contrast when the image first displays. The default value is 0. The range of values is -100 to 100.

This setting does not apply to bitonal, PDF, and CAD images.

• PDF Password - This setting allows Prizm Viewer to set the default password used when attempting to open a password protected PDF file.
