Printed Documents (different printer): Accounts for variations introduced by different printers.
Scanned Documents: Optimized for comparing scanned documents, which often have distortions and imperfections.

Each comparison type has pre-configured settings that can be adjusted to suit specific needs. You can also create custom comparison types by selecting the appropriate settings and saving them for future use.

2.3 Detailed Breakdown of Comparison Options

The Comparison Options section allows you to adjust parameters related to how Revu analyzes the documents for differences.

2.3.1 Grid Size

The Grid Size setting defines the size of the individual grid segments used for comparison. Revu breaks down the document into a grid and compares each segment for differences. A smaller grid size increases the sensitivity of the comparison but may also result in more false positives.

Impact:
- Smaller Grid Size: More sensitive, captures finer details, but may also highlight insignificant differences.
- Larger Grid Size: Less sensitive, may miss subtle differences, but reduces false positives.
Use Case: Adjust the grid size based on the level of detail required and the complexity of the documents. For documents with fine lines and intricate details, a smaller grid size is recommended. For simpler documents, a larger grid size may suffice.

2.3.2 Pixel Density

Pixel Density controls the threshold amount of differences in a particular area (defined by the Grid Size) when detecting differences. This setting determines how much variation is allowed within a grid segment before it is flagged as different.

Impact:
- Higher Pixel Density: Requires more significant differences within a grid segment to be flagged.
- Lower Pixel Density: Flags even minor differences within a grid segment.
Use Case: Adjust pixel density based on the expected level of variation between the documents. If the documents are expected to be nearly identical, a lower pixel density is appropriate. If there are likely to be more significant changes, a higher pixel density may be necessary.

2.3.3 Color Sensitivity

Color Sensitivity determines the threshold at which pixel color differences will be detected. A lower sensitivity setting will not detect as many differences as a higher sensitivity setting.

Impact:
- Higher Color Sensitivity: More sensitive to color variations, flags even slight color changes.
- Lower Color Sensitivity: Less sensitive to color variations, ignores minor color differences.
Use Case: Adjust color sensitivity based on the color accuracy required. If color is critical, a higher sensitivity is needed. This setting works in conjunction with the Pixel Proximity Allowance. Increase this value to check adjoining areas for similar pixels.

2.3.4 Pixel Proximity Allowance

The Pixel Proximity Allowance works in conjunction with Color Sensitivity. It checks adjoining areas for similar pixels. Increasing this value can help reduce false positives by considering the surrounding pixel colors.

Impact:
- Higher Allowance: More tolerant of minor color variations in adjacent pixels.
- Lower Allowance: Less tolerant of color variations, flags even slight differences.
Use Case: Useful when dealing with scanned documents or images where color accuracy may be compromised.

2.3.5 Margin

The Margin value allows you to ignore regions around the borders of the PDFs being compared. This is useful for excluding extraneous information or artifacts that may be present along the edges of the documents.

Impact:
- Larger Margin: Ignores a larger area around the document borders.
- Smaller Margin: Ignores a smaller area around the document borders.
Use Case: Helpful when comparing documents with inconsistent borders or when you want to focus on the central content.

2.3.6 Offset

The Offset setting is used if you know one document is offset from the document being compared. You can enter values to compensate for the offset and align the documents for accurate comparison.

Impact: Aligns the documents based on specified horizontal and vertical offsets.
Use Case: Useful when comparing documents that have been misaligned during scanning or printing.

2.3.7 Auto-alignment

Check Auto-alignment to instruct Revu to automatically align the drawings or documents being compared. This is particularly useful for scanned drawings where manual alignment may be difficult.

Impact: Automatically aligns the documents before comparison.
Use Case: Recommended for comparing scanned drawings or documents that are not perfectly aligned.

2.4 Rendering Options Explained

The Rendering Options section controls how Revu rasterizes the PDFs before comparison.

2.4.1 DPI

DPI (Dots Per Inch) determines the resolution used to rasterize the PDFs. The default setting is 72. Setting a higher value (e.g., 144) increases the resolution and may be necessary for finer details.

Impact:
- Higher DPI: Higher resolution, captures finer details, but increases processing time.
- Lower DPI: Lower resolution, faster processing, but may miss fine details.
Use Case: Increase DPI when comparing documents with intricate details or small text.

2.4.2 Include Markups

By default, Revu ignores existing markups on the documents. Select Include Markups to override this behavior and render markups for comparison.

Impact: Compares the markups present in the documents.
Use Case: Useful for tracking changes to markups over time or ensuring that markups have been correctly implemented.

2.4.3 Include Flattened Markups

While flattened markups become part of the PDF’s content layer, Revu ignores those that have been flattened as “recoverable” by default. Select Include Flattened Markups to override this behavior.

Impact: Compares flattened markups as part of the document content.
Use Case: Useful when comparing documents with flattened markups that need to be included in the comparison.

2.5 Markup Options: Customizing the Visuals

The Markup Options section allows you to customize the appearance of the markups used to highlight differences.

2.5.1 Color, Fill Color, Opacity, and Width

Determine the appearance of the markups by setting the Color, Fill Color, Opacity, and Width. These settings control the visual prominence of the difference annotations.

Impact: Customizes the appearance of the markups.
Use Case: Choose colors and styles that are easily visible and distinguishable from the document content.

2.5.2 Cloud

Check Cloud if cloud markups should be used to highlight differences.

Impact: Uses cloud markups instead of solid shapes.
Use Case: Cloud markups can be more visually appealing and less intrusive than solid shapes.

2.5.3 Locked

If the annotations should be locked when they are placed, check Locked.

Impact: Prevents accidental modification of the difference annotations.
Use Case: Ensures that the difference annotations remain unchanged during review.

2.5.4 Subject

Enter a name for the difference annotations (e.g., “Differences 5-7-14”) in the Subject field. This makes it easy to group the difference annotations together on the Markups list by sorting by Subject.

Impact: Groups the difference annotations in the Markups list.
Use Case: Useful for tracking changes over time and organizing multiple comparison results.

2.5.5 Apply To

Select which document the difference annotations should be added to from the Apply to dropdown list. Options include adding the annotations to one of the existing documents or creating a new copy with the annotations.

Impact: Determines where the difference annotations are added.
Use Case: Choose the option that best suits your workflow and collaboration needs.

2.5.6 File Suffix

Enter a File Suffix that will be appended to the comparison document file name. This makes it easier to differentiate the comparison document from the originals.

Impact: Adds a suffix to the file name of the comparison document.
Use Case: Helps in identifying the comparison document and distinguishing it from the original files.
