Microsoft Publisher can import many common PC graphic formats. This table lists which versions of Publisher can import which types of graphics.

Bitmap Formats Version 1 2 3 97 Extension
------------- ------------------ ---------

Bitmap X X X X .bmp
PC Paintbrush X X X X .pcx
Photo CD X X X X .pcd
Tagged Image Format X X X X .tif
JPEG Picture Format X X .jpg
CompuServe Graphics X .gif

Vector Formats Version 1 2 3 97 Extension
-------------- ------------------ ---------

Computer Graphic Metafile X X X X .cgm
DrawPerfect X X X X .wpg
Encapsulated PostScript X X X X .eps
Micrografx Designer X X X X .drw
Windows Metafile X X X X .wmf
CorelDRAW X X .cdr
Be certain that when importing one of the graphic formats listed above that the correct file extension is used. Publisher determines what graphic import filter to apply to a particular file, based solely on the file extension.

More Information

The types of graphics that can be imported into Publisher fall into two main categories; Bitmap (Paint-Type) and Object-Oriented (Draw-Type).

Bitmap Graphics

Bitmap graphics are commonly created by basic painting packages, such as Windows Paintbrush. Most scanning packages also utilize bitmap formats. Bitmaps are comprised from a series of small square dots. Depending on the format of the particular bitmap, each of these dots can be black, white, some particular color, or a shade of gray.

Limitations of Bitmaps

There are several limitations to note when dealing with bitmap graphics:

  1. Because bitmaps are made up of dots, sizing the graphic may distort it. Sizing the graphic proportionally minimizes the distortion.
  2. Bitmap graphics can be very large. Scanned bitmaps at 300 DPI can easily exceed 1 MB. This causes slow screen redraws and creates larger Publisher files. Printing problems may also occur with large images.
  3. Bitmaps do not typically output at as high a resolution as an equivalent object-oriented graphic format.

Object-Oriented Graphics

Object-oriented graphics, on the other hand, are not comprised of a series of dots. They are a set of instructions that tell the computer to draw lines, boxes, polygons, and so on. Such a file is basically an equation for generating the image, rather than the actual pixel by pixel representation. Object-oriented graphics have several advantages over bitmaps.

  1. A graphic can usually be resized without distorting the image. Because object-oriented graphics are generated by a formula, resizing plugs different values into the formula to compensate for the change in size.
  2. Object-oriented graphic files are much smaller in size.
  3. They output at the highest resolution supported by the output device. In other words, if you send an object-oriented graphic to a 1024 x 1024 resolution printer, the graphic would recalculate and output at that resolution. A bitmap, on the other hand, is always limited by the initial resolution at which it was created. In most cases, this is no better than the screen resolution, 75 DPI for VGA, unless the image was scanned.
Typical programs using object-oriented graphics are CorelDRAW!, Micrografx Designer, Microsoft PowerPoint, Microsoft Excel, and many others.
