General Techniques for Optimizing PDF Files
8.1 Use short names
8.2 Use direct and indirect objects appropriately
8.2.1 Minimizing object size
8.2.2 Sharing objects
8.2.3 Placeholder for an unknown value
8.3 Take advantage of combined operators

Use… Instead of…
8.4 Remove unnecessary clipping paths
8.5 Omit unnecessary spaces
8.6 Omit default values
8.7 Take advantage of forms
8.8 Limit the precision of real numbers
8.9 Write parameters only when they change
8.10 Don’t draw outside the crop box
8.11 Consider target device resolution
8.12 Share resources
8.13 Store common Page attributes in the Pages object

Optimizing Text
9.1 Don’t produce unnecessary text objects
Example 9.1 Changing the text matrix inside a text object
9.2 Use automatic leading
Example 9.2 Multiple lines of text without automatic leading
Example 9.3 Multiple lines of text using automatic leading
Example 9.4 TJ operator without automatic leading
Example 9.5 Use of the T* operator
Example 9.6 Using the TL operator to set leading
Example 9.7 Using the TD operator to set leading
9.3 Take advantage of text spacing operators
Example 9.8 Character and word spacing using the Tc and Tw operators
Example 9.9 Character and word spacing using the " operator
9.4 Don’t replace spaces between words
9.5 Use the appropriate operator to draw text

CHAPTER 10
Optimizing Graphics
10.1 Use the appropriate color-setting operator
10.2 Defer path painting until necessary
Example 10.1 Each path segment as a separate path
Example 10.2 Grouping path segments into a single path
10.3 Take advantage of the closepath operator
Example 10.3 Using redundant l and h operators to close a path inefficiently
Example 10.4 Using the l operator to close a path inefficiently
Example 10.5 Taking advantage of the h operator to close a path
10.4 Don’t close a path more than once
Example 10.6 Improperly closing a path: multiple path closing operators
Example 10.7 Properly closing a path: single path closing operator
10.5 Don’t draw zero-length lines
10.6 Make sure drawing is needed

Optimizing Images
11.1 Preprocess images
11.2 Match image resolution to target device resolution

Example 12.3 Images and image masks
12.4 Blends
1. Create the image containing the blend.
2. Draw the shape to be filled with the blend and make it the current clipping path.
3. Scale and translate the image using the cm operator so that it completely fills the shape.
4. Draw the image using the Do operator.
5. Remove the clipping path created in Step 2 so that any subsequent drawing is not restricted to...
