In the Reference Manager palette, you can use Reload to reload an unloaded
image or to update a loaded image by reloading the image from the specified
directory path. If a drawing is closed after an image is unloaded, the image
file is not loaded when the drawing is next opened; you must reload it.
Improve the Display Speed of Raster Images
To increase the display speed of images, you can change image display quality,
hide images not currently needed, use image tiling, or suppress image selection
highlighting.
To increase the display speed of images, you can change image display quality
from the default high quality to draft quality. Draft-quality images appear
more grainy (depending on the image file type), but they are displayed more
quickly than high-quality images. Use the IMAGEQUALITY system variable
to control image quality.
You can improve the image quality when using True Color (24 or 32 bits per
pixel) for raster images by setting certain drafting environment options. When
images are displayed at optimum quality, regeneration time increases
significantly. To improve performance, decrease the number of colors for the
system display setting while working in a drawing.
You can increase redrawing speed by hiding images you do not need in the
current drawing session. Hidden images are not displayed or plotted; only the
drawing boundary is displayed. You can choose to hide an image regardless
of the user coordinate system (UCS) in the current viewport.
Use Tiled Images
Tiled images are small portions (a series of tiles) of large images that load much
faster than non-tiled images. If you edit or change any properties of an image,
only the modified portion is regenerated, thus improving the regeneration
time. TIFF (Tagged Image File Format) is the only tiled format that the program
supports. The TIFF reader supports all image types:
Bitonal (1 bit per pixel)
Gray scale and indexed color (8 bits per pixel)
True Color (24 or 32 bits per pixel)
You can save tiled TIFF images with most image scanning tools. The image
tiles should be no smaller than 64 x 64 pixels and no larger than 512 x 512
pixels. Additional file readers that support other tiled formats, such as CALS
Type II, are available from third-party developers.
