For more information about importing bitmaps, see Importing Bitmap Image Data and the Import Setup Dialog.
This dialog is accessed either from the Import Setup Dialog or from the Edit - Modify Selected Features - Properties menu. It allows you to change the following parameters:
The directory and file name of the bit map is displayed. Pressing the Browse button allows you to select another file or path.
Note: The file name will not be displayed if you have accessed this dialog during import of the bitmap.
Allows you to position the bitmap according to one of its corners. Enter the x, y coordinate in project coordinates and the corner reference.
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.
It is possible to explicitly modify and clear the image cropping limits. See also Image Cropping.
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. See also Image Cropping.
The bitmap image is displayed.
Only the border is displayed with the name of the bitmap at the center.
The entire bitmap and border is not displayed. This is analogous to setting a features properties to No Display.
Setting the washout factor allows you to fade the image. A factor of 0 has no washout and 1 is fully faded.
A rotation angle in degrees can be specified. Note: rotating large bit maps can be slow.
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.
