Steps to Crop a Raster Image in MicroStation

Cropping a raster image effectively in MicroStation requires careful interaction with multiple tools within the software. Follow these detailed steps to achieve your goal of cropping a raster image.

Preparing Your Workspace

1. Open the Raster Manager:

   • Start MicroStation and load your design file.
   • Access the Raster Manager by selecting File > Raster Manager or clicking on the Raster Manager icon in the Primary Tool Bar.
2. Attach the Image:
   • Click File > Attach > Raster to import the raster image you want to crop.
   • Locate and select the image file from your system, then click Open.
   • The Raster Attachment Options will appear. Ensure all settings are as you need, then click Attach.

Defining the Crop Area

1. Set Up a Fence:

   • Use the Place Fence tool to draw a fence around the desired crop area on your raster image. This fence acts as the boundary for your cropping operation.
2. Select the Clip Mask Tool:
   • Navigate to the Tool Settings window.
   • Look for the option labeled Apply Clip Mask By 2 Points. This allows you to specify your cropping bounds.

Executing the Crop

1. Specify the Crop Area:

   • Click on two data points within the fence to define the rectangular area you want to keep from the raster image. The two points should outline opposite corners of your cropping rectangle.
2. Apply the Clip Mask:
   • After setting the points, the application will process this information and will apply the clip mask to your raster image, effectively cropping it within the defined boundaries.

Finalizing Your Cropped Image

1. Check the Results:

   • Review the cropped image to ensure it appears as you wanted. If necessary, you can make adjustments by repeating the above steps with a new fence or selecting different points for your crop.
2. Manage Other Views:
   • If multiple views are open, ensure you apply your clipping in the relevant view. You can adjust as needed in any view by clicking within that specific panel.
