Summary
The best method for including logos in map documents is to insert them as EMF images. Instructions provided describe how to convert original logo artwork or a bitmap logo (if the original artwork is unavailable) to EMF.
Procedure
- Convert the original artwork to EMF using the graphics application that the original artwork was created in.
Note:
If Adobe Illustrator is used to create the EMF file, a PC running Adobe Illustrator should be used. Since EMF is a Windows file format, EMFs generated in Illustrator on a Macintosh platform tend to be of lower quality.
- If the original vector artwork is available as PostScript, but Adobe Illustrator or a similar graphics application that can convert PostScript to EMF is not available, use the freeware application pstoedit.
See the link in the Related Information below for more information on pstoedit. - If the original vector artwork cannot be located, there are several freeware raster-to-vector converters or tracing programs, such as Potrace, Autotrace and KVEC.
See the links in the Related Information below.
Note:
Potrace is freeware but only traces 1-bit or black and white images. KVEC, a shareware application, and Autotrace can be used to trace color bitmaps.
- If converting the bitmap logo to vector is impossible, and the background of the logo needs to be transparent, the bitmap marker method can work.
- In a graphics editor application such as Adobe Photoshop, fill the white, background portions of the logo that need to be transparent with a key color that does not appear elsewhere in the map; for example, bright magenta. This allows any areas of the logo that should be opaque white to remain opaque on the map.
- Note the RGB values of the key color as they will be needed later.
- Save the new image in BMP format.
- In ArcMap, place a marker on the layout using the Drawing toolbar's New Marker tool (see image below).
- Double-click this new marker to open the Properties dialog box and click the Change Symbol button.
- Click the Properties button and select Picture Marker Symbol from the Type drop-down list.
- Navigate to the new logo BMP created previously and click OK.
- Use the RGB values used for the key color in the Transparent Color picker.
- Adjust the size of the marker as necessary and click OK on all of the dialog boxes.
Note:
Picture marker symbols are affected by the Output Image Quality setting on output and may not produce the best quality for the logos when printed or exported.
