In AutoCAD, you typically control the display and plot quality of an attached raster image rather than changing its inherent file resolution directly within the drawing environment. You can adjust these settings using the Properties palette.
To adjust settings that influence the appearance or display quality (often perceived as "resolution" in the context of how it looks or plots) of an image in AutoCAD, follow these steps using the Properties palette:
Adjusting Image Display Options
Controlling the display quality of an attached image ensures it appears or plots correctly within your AutoCAD drawing. This doesn't alter the original image file's pixel dimensions but affects how AutoCAD renders it.
Here is the standard method:
- Select the Image: Click on the image in your drawing to select it.
- Access Properties: Right-click the image.
- Open Properties Palette: Click Properties from the right-click context menu.
- Modify Display Settings: In the Properties palette that appears, locate and select one of the display options.
The Properties palette offers various settings for an image object. While the exact "display options" can vary slightly depending on the AutoCAD version and image type, they often include controls related to visual quality and appearance within the drawing.
Common Image Display Settings in Properties
Within the Properties palette for a selected image, you might find settings under categories like "Plot Quality" or "Adjust". These settings influence how the image is rendered on screen and when plotted.
Some typical settings you might encounter as "display options" include:
- Image Quality: Often provides options like Draft or High. Selecting "High" generally results in a better visual representation during plotting, effectively using more detail from the image file.
- Display Mode: Options like Greyscale, Monochrome, or Color allow you to control how colors are displayed.
- Fade: Adjusts the transparency of the image.
- Transparency: Toggles transparent areas on or off.
By selecting the appropriate "display options" like Image Quality in the Properties palette, you can control the visual fidelity of the image within your AutoCAD drawing and subsequent plots, which is often what users mean when asking about changing resolution in this context.
Remember that for true resolution changes (like changing pixels per inch), you would need to edit the image file in an image editing software (like Photoshop, GIMP, etc.) before attaching or re-attaching it to your AutoCAD drawing.
