3. Description
This Fixup can be used to derive a selected Page Box from entered color values. The box is set to the enclosing rectangle of the found vector objects.
Values are rounded!
The Fixup traces color objects in the background in order to subsequently place the desired box. Due to the fact that those values must be rounded, slight deviations may occur in some cases when placing the Page Boxes.

- CMYK color picker [2] – enter the desired CMYK color values from which the Page Box should be derived. The entered color is displayed in the preview image.
- Offset [3] – enter the desired Offset for Top, Bottom, Left and Right for the selected Page Box here. In case the offset differs first unlock the lock symbol.

3.2. Before/After
To experiment with this function, refer to the sample file "Sample_Derive PageBox from Colored Objects.pdf". The file has a size of 200 x 200 mm. All Page Boxes have this size. The TrimBox should be derived from the background colors (CMYK 30/25/25/5).
After applying the Fixup, the file "Sample_Derive PageBox from Colored Objects_End.pdf" is created. Here, the TrimBox was derived from the background color. The values from Figure 1 were used.
