3. Description
This Fixup can be used to derive a selected PageBox 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 PageBoxes.
3.1. Prerequisites and Functionality
For the Fixup to perform as intended, the following requirement must be met:
- The file contains CMYK vector objects.

Select the following options to derive a PageBox from colored objects:
- PageBox [1] – select the desired PageBox that should be derived from colored objects in the selection menu. The following options are available:
- TrimBox – the TrimBox is placed on the enclosing rectangle of all found vector objects.
- BleedBox – the BleedBox is placed on the enclosing rectangle of all found vector objects.
- MediaBox – the MediaBox is placed on the enclosing rectangle of all found vector objects.
- CropBox – the CropBox is placed on the enclosing rectangle of all found vector objects.
- Variable Content [4] – for Variable Content [4], select the desired placeholder – Database Field or User-defined Field – from which the value for the PageBox selection should be retrieved. The following values must be present in the selected field so that the selection is executed:
TrimBox
- Bleed
BoxMediaBoxCropBox
- CMYK color picker [2] – enter the desired CMYK color values from which the PageBox 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 PageBox here. In case the offset differs first unlock the lock symbol. For Variable Content [5], select the desired placeholder – Database Field or User-defined Field – from which the value for the Offset should be retrieved.

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 PageBoxes 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 generated. The TrimBox was derived from the background color. The values from Figure 1 were used.
