Correction

It is used when aligning distorted objects such as scanned images, or when the layout is changed and the differences cannot be easily identified just by overlapping

By turning on "Apply to all pages", all pages after the currently displayed page will be corrected automatically

MIIDEL operation will not be available when automatic correction is in progress

Auto:Distortion correction

This feature automatically corrects scanned images with distortion or pages with different sizes to align them with the modified page, making it easier to identify changes

Auto:Layer correction

You can automatically break down the parts within a page and compare them by automatically overlaying similar parts

Layer correction takes a lot of processing time

Pages with text as the main content require more processing time compared to pages with images as the main content

The larger the paper size, the longer the processing time required

SemiAuto:Three-point correction

Select three points on pages with different layouts, such as structural diagrams and facility diagrams, drawings and photographs, and align those points to make it easier to find the differences

Three-point correction requires manual adjustment, unlike the Auto:Auto correction

As an example, the blue shaded area and the red shaded area are superimposed

1. Move the 〇 located at three corners of both the before and after versions to specify reference points

   

2. Set the reference points for both the before and after images, then click the OK button in the upper right corner to perform the correction

   

3. By indicating three points on the originally differently scaled and positioned drawings, they can be compared more easily

   

SemiAuto:Layer correction

Manually specify parts within a page to automatically overlay similar parts and facilitate finding changes

SemiAuto:Layer correction is used when correction cannot be done by methods such as Auto:Distortion correction,Auto:Layer correction or SemiAuto:Three-point correction
