dilation-erosion menu

Dilation and Erosion are operations that change the size of objects in a bitmap image. When you dilate a bitmap, the system adds an extra row of black pixels around the boundary of each object in the bitmap. Similarly, when you erode a bitmap, the system strips off a row of black pixels from the edges of each object in the bitmap.

The procedure for using this menu is:

You specify the name of the bitmap you want to use in the Bitmap file menu field.
You click on either DILATE or ERODE to do whichever function. You can specify how many times you want to dilate or erode by entering the number in the Repeat count menu field.
You can display the results at any time by clicking on the DISPLAY menu field. If you have made blowups from the main image display, you can update them by clicking on the UPDATE BLOWUP IMAGES menu field.
If you want to save the results of the dilation-erosion you can:
- click on OVERWRITE BITMAP to store the new bitmap over the old one.
- click on SAVE NEW VERSION to create a new bitmap image with the same name as the original one.
- click on SAVE NEW BITMAP to create a new bitmap, using the name specified in the New bitmap menu field.
