PUB98: Large Graphics May Not Import Into Publisher (191438)

CAUSE

The graphic filters that ship with Publisher cannot handle pictures that contain more than 16 megabytes (MB) of uncompressed data. In addition, Publisher cannot store pictures that contain more than 16 MB of data.

NOTE: The amount of disk space required to store a graphic file has little relationship to how much picture data that image contains. For example, Joint Photographic Expert Group (JPEG) files are extremely compressed. In other words, a JPEG file that has a file size of 300 kilobytes (K) might contain more than 25 MG of data. On the other hand, an AutoCAD Data Exchange File (DXF) image may require 2 MB of disk space and contain only 60 K of picture data.

WORKAROUND

In most cases it is not necessary to use very large graphics in Microsoft Publisher. You can reduce the resolution and color depth of the image and not sacrifice quality by using one of the following methods.

Method 1: Crop the image before importing it into Publisher

If you don't need to use the entire picture, you can use a photo editing or paint program, such as Microsoft Photo Editor or Adobe PhotoDeluxe, to select only the part the image you want to use.

Method 2: Reduce the color depth of the picture

If you are printing to a black and white printer, you can reduce the file size by converting a color image to grayscale. Or, in some cases, you can reduce a 24-bit (16.7 million) color image to 256 colors without any noticeable loss of quality.

Method 3: Reduce the size of the picture

If you scanned an 8- by 10-inch picture to use in a 4- by 5-inch picture frame, rescan the image at a smaller scale.

Method 4: Scan the image at a lower resolution

While many scanners scan at 600 dots per inch (dpi) or higher, you should scan a color or grayscale image at no more than 300 dpi. An exception to this is if you are scanning a very small image and you do not want the image to become distorted, grainy, or jagged when you enlarge it in Publisher.
