ADOBE ACROBAT 3D VERSION 8 498 User Guide Q Groups all operators in the content stream that belong to the same graphic state nesting level within a pair of the q/Q operators. Expand the subtree for a q/Q pair to view the operator and parameters inside. BMC Similar to Q, but arranges content streams by marked content (BMC/EMC) nesting levels. BT/ET Arranges content streams by text blocks, which are enclosed by BT and ET operators. Snippet Displays content streams as a series of snippets. A snippet is a contiguous group of objects that share the same graphic state. In this view, each snippet represents a type of drawing operation (for example, paint area) and its graphic state. You can also view content streams as snippets by selecting Show Selected Page Object In Snap View in the Preflight window. Browse the internal font structure View the internal structure of embedded fonts in a PDF in greater detail than the preflight results with a graphical view that shows the outline and coordinates of each glyph. You can determine the source of various preflight problems, such as mismatches caused by inconsistent glyph widths. Before you can browse the internal font structure, you must run a preflight check. 1 In the Preflight window, choose Browse Internal Structure Of All Document Fonts from the Options menu. To view the structure of a single font, expand the Fonts entry in the results, select a font, and choose Browse Internal Font Structure from the Options menu. 2 To view the glyph details, click any of the following buttons: Display Grid Shows the origin of the glyph's coordinate space, indicated by two green-colored orthogonal lines. Display Boxes Shows the area used by the selected glyph and the maximum area used by all glyphs using blue lines that coincide on the top and bottom. Display Filling Shows the areas of a filled glyph as medium gray. Display Points Shows all the points used to define the glyph's outline. Black points indicate the outline's contour. Red points indicate bezier curves and are offset from the outline's contour. Display Cursor Shows the position of the currently selected point, indicated by two magenta-colored orthogonal lines. This button is available only if Display Points is selected. 3 To adjust the size of the glyph display area, drag the handle between the tree view and the glyph display area up or down. Preflight profiles About preflight profiles The success of a preflight inspection depends on how well you define the criteria for the inspection. The inspection criteria are packaged in a file called a preflight profile. A preflight profile includes one or more checks; each check includes one or more property statements that validate the PDF content. Preflight shows an error only if all the property statements in the check are in error. In the Preflight Edit Profile dialog box, you can specify which values to use and how to handle mismatches. For example, you can choose a profile that simply reports mismatches, or one that automatically fixes a mismatch according to its specified parameters. A profile with a fixup has the gray wrench icon next to it.

Q
Groups all operators in the content stream that belong to the same graphic state nesting level within a pair of
the q/Q operators. Expand the subtree for a q/Q pair to view the operator and parameters inside.
BMC
Si
milar to Q, but arranges content streams by marked content (BMC/EMC) nesting levels.
BT/ET
Arranges content streams by text blocks, which are enclosed by BT and ET operators.
Displays content streams as a series of snippets. A
snippet
is a contiguous group of objects that share the
same graphic state. In this view, each snippet represents a type of drawing operation (for example, paint area) and its
graphic state.
You can also view content streams as snippets by selecting Show Selected Page Object In Snap View in the Preflight
window.
Browse the internal font structure
View the internal structure of embedded fonts in a PDF in greater detail than the preflight results with a graphical
view that shows the outline and coordinates of each glyph. You can determine the source of various preflight
problems, such as mismatches caused by inconsistent glyph widths.
Before you can browse the internal font structure, you must run a preflight check.
1
In the Preflight window, choose Browse Internal Structure Of All Document Fonts from the Options menu.
To view the structure of a single font, expand the Fonts entry in the results, select a font, and choose Browse Internal
Font Structure from the Options menu.
2
To view the glyph details, click any of the following buttons:² ²
Display Grid
Shows the origin of the glyph’s coordinate space, indicated by two green-colored orthogonal lines.² ²
Display Boxes
Shows the area used by the selected glyph and the maximum area used by all glyphs using blue² ²
lines that coincide on the top and bottom.² ²
Display Filling
Shows the areas of a filled glyph as medium gray.
Display Points
Shows all the points used to define the glyph’s outline. Black points indicate the outline’s contour. Red
points indicate bezier curves and are offset from the outline’s contour.
Display Cursor
Shows the position of the currently selected point, indicated by two magenta-colored orthogonal
lines. This button is available only if Display Points is selected.

To adjust the size of the glyph display area, drag the handle between the tree view and the glyph display area up
or down.
Preflight profiles
About preflight profiles
The success of a preflight inspection depends on how well you define the criteria for the inspection. The inspection
criteria are packaged in a file called a
preflight profile
. A preflight profile includes one or more checks; each check
includes one or more property statements that validate the PDF content. Preflight shows an error only if all the
property statements in the check are in error. In the Preflight Edit Profile dialog box, you can specify which values
to
use
and
how
to
handle
mismatches.
For
example,
you can
choose
a profile that
simply reports mismatches, or
one
that automatically fixes a mismatch according to its specified parameters. A profile with a fixup has the gray wrench
icon next to it.
