Pitney Bowes MapInfo Professional - Manual (Page 125)

The following sections explain the display settings, the printing options, and window export options in
Output Preferences dialog box. Some of the options appear in more than one dialog so we have grouped
all of the same explanations together.
Display tab (Output Preferences)
The Display tab sets the on-screen display options for raster or grid files.
• Polygon Mode - Select this check box to display the rendering that draws the object as a single request
with all nodes. Polygon Mode has three preferences based on three types of drawing: on-screen,
printing, and exporting. You can select Polygon Mode separately for display, printing, and export on
the Display, Printing, and Exporting tabs. When Polygon Mode is off, MapInfo Professional renders
with special processing.
Printing to PDF files may produce extra hairlines in the output when Polygon Mode is off. Note:
• Display Raster in True Color When Possible - Select this check box to display your 24-bit raster or
grid file images in true color (make sure your display settings are set to greater than 256 colors). Clear
this check box to display images using 256 colors. This box is checked by default.
• Dither Method - Select this check box when it is necessary to convert a 24 image to 256 colors, use
either halftone or error diffusion. This option is used when printing raster and grid images. Dithering
occurs when Print Raster In True Color When Possible is off or when the printer color depth is 256
colors or less. Select a dither method from the drop-down list:
Halftone dithering calculates a series of half tone differences in color between high-contrast elements
in your image to create a smooth transition of color. This option is selected by default for display, print,
and export options.
Error diffusion dithering calculates an interim color between contrasting colors and shades the
surrounding pixels to blend evenly toward that interim color.
You can select dithering separately for display, printing, and exporting on the Display, Printing,
and Exporting tabs. Note:
Printing tab (Output Preferences dialog box)
Click the Printing tab to set the printing options for Map windows, classic Layout windows, Layout
Designer windows, and all other output file types. Select the appropriate printing settings based on your
output requirements. Remember that resetting these printer options locally overrides these preferences.
• Print Directly to Device - Select this option to print your image file directly from MapInfo Professional.
This check box is checked by default.
• Print Using Enhanced Metafile (EMF) - Select this option to generate an enhanced metafile of your
MapInfo Professional image before sending it to the printer. This setting takes advantage of current
printer technology to shrink the spool size and print your file quicker without sacrificing quality. When
printing to PDF, selecting this option generates a flat, non-layered, PDF file.
You must use this setting if you are printing a map containing a translucent raster or grid layer.
If you do not use this setting, the image will not print translucently. Note:
• Output Method/Print Using Offscreen Bitmap (OSBM) - Select this option to generate an Offscreen
bitmap of your MapInfo Professional image before sending it to the printer. Offscreen bitmap is invoked
depending upon the type of translucent content in the map and enhanced rendering state of the window.
However, setting OSBM from this window means that while printing Offscreen bitmaps (OSBM) will
be selected regardless of the translucency and anti-alias settings.
• Print Border for Map Window - Select this check box to print a black border around the image you
are printing. Clear this check box to leave the image without a border. This check box is checked by
default.
• Internal Handling for Printing Transparent Vector Fills and Symbols - Select this check box to
have MapInfo Professional handle transparent fill patterns and bitmaps for vector images when printing
