The Import Bitmap Options Dialog allows you to change the following parameters:
File Path name
The directory and file name of the bit map is displayed. Pressing the Browse button allows you to select another file or path.
Reference Coordinate
Allows you to position the bitmap according to one of its corners. Enter the x, y coordinate in project coordinates and the corner reference.
Pixels
The bitmap image is made up of a series of pixels (dots). The number of pixels is shown. Changing the size of the bitmap in X and Y directions will enlarge or reduce the image size.
Cropping
It is possible to explicitly modify and clear the image cropping limits. See also Image Cropping.
Image Quality
The image quality allows you to control the image resolution. This option is only available for some types of images such as TIF, JPG, MrSID, JP2 and ECW. Higher quality images are larger and slower to load.
Image Display
Display All
The bitmap image is displayed.
Border Only
Only the border is displayed with the name of the bitmap at the center.
Hide
The entire bitmap and border is not displayed. This is analogous to setting a features properties to No Display.
Washout
Setting the washout factor allows you to fade the image. A factor of 0 has no washout and 1 is fully faded.
Adjustment
Rotation Degrees
A rotation angle in degrees can be specified. Note: rotating large bit maps can be slow.
Rubbersheet
Interpolation Method
World File Georeference
Clicking the Open button will load the location and scaling information from the external world file if it exists.
Clicking the Save button will update the world file with the new location and scaling information. A new world file will be created if one doesn't already exist.
