The GUI documentation for //Ignore rotated text// describes the current profile sidebar of i-net PDFC. In the sidebar, the checkbox is shown in the Text group under Advanced text options. It is available only when text comparison is active.
The current i-net PDFC implementation controls this option through the filter list:
| Raw key | Value | Meaning |
|---|---|---|
FILTERS | contains HIDEROTATEDTEXT | Enables the filter for rotated text. The filter list can contain additional identifiers. If the identifier is absent, the filter is disabled. |
INVISIBLEELEMENTS_HIDE_ROTATION | do not use | This key is not a current raw profile value of the HideRotation implementation. It must not be documented or added to a profile alongside the filter identifier. |
The filter is registered with the identifier HIDEROTATEDTEXT. A profile fragment for enabling it is:
<entry key="FILTERS">HIDEROTATEDTEXT</entry>
The structure or UI key pdfc.filter.hide_rotation maps the checkbox to the FILTERS list. When enabled, HIDEROTATEDTEXT is added; when disabled, the identifier is removed from the list. At runtime, the implementation processes this filter after OCR processing and before basic table detection.
