Understanding Raster Images in AutoCAD

Raster images consist of pixel-based graphics such as JPEG or TIFF files. Unlike vector graphics, which are composed of lines and shapes, raster images are made up of tiny dots of color, making them less flexible when it comes to scaling. When working with AutoCAD, keep in mind that raster images cannot be embedded directly into the drawing; they must remain as separate file references. If you need to send a drawing that includes raster images, ensure that the associated files are included.

Steps to Hide a Raster Image in AutoCAD

To hide raster images effectively within your drawing, you can follow this step-by-step guide:

Step 1: Access the Command Line

Begin by accessing the command line within AutoCAD. This feature is usually located at the bottom of the application window.

Step 2: Enter the IMAGEFRAME Command

Type IMAGEFRAME into the command line and press Enter. This command allows you to manage the visibility of image boundaries for raster images.

Step 3: Choose the Desired Setting

You will be prompted to enter a value. Here are the available options:

• 0: To hide both the image and its boundary.
• 1: To display the image and plot its boundary.
• 2: To show the image during editing but hide its boundary during plotting.

For the purpose of hiding an image completely, type 0 and press Enter. This will render the image invisible in your drawing.

Viewing Hidden Images

If you need to verify whether an image is still attached without displaying it, utilize the External References palette. To open this:

1. Navigate to the View tab on the ribbon.
2. Click on the External References panel.
3. Here, involved images will be listed, even if they are currently hidden.

Steps to Unhide a Raster Image

In case you need to restore visibility to your hidden image, follow these simple steps:

1. Again, type IMAGEFRAME in the command line and press Enter.
2. Enter 1 to re-display the image and its boundary, or 2 to show the image but not plot its boundary.

Additional Image Management Options

Attaching Raster Images

If you’re working with new raster images, you can attach them:

1. Open the External References palette from the View tab.
2. Click on Attach Image and navigate to select your desired image file.
3. Click Open to include it in your drawing.

Modifying Raster Images

If you want to resize or manipulate the raster image further, you can adjust its properties using the Properties palette. Right-click the image and select Properties to change its dimensions, position, and layer settings.

FAQ

Q1: Can I permanently remove a raster image from my AutoCAD drawing?
Yes, you can delete the image from the External References palette. Right-click the raster image and select "Detach" to remove it completely from the drawing.

Q2: What file formats can I attach as raster images in AutoCAD?
AutoCAD supports various raster image formats such as JPEG, TIFF, BMP, and PNG for attachment.

Q3: Why can’t I see my raster image after attaching it?
If the attached image is not visible, check the IMAGEFRAME setting, or ensure that the image is not hidden due to its boundary settings. You may also want to verify that the image file is correctly linked and accessible.
