THPDFOCRRequest Record

Describes one rendered loaded page together with the limits an IHPDFOCREngine must honour

Fields

• PageIndex, DPI, and PageRotation identify the rendered page and normalised rotation
• PageLeft, PageBottom, PageRight, and PageTop expose the rendered page box in PDF user space — the crop box clipped to the media box, i.e. the area the bitmap actually covers
• Bitmap is a borrowed top-left-origin page raster valid only during Recognize
• MaxWords and MaxTextCodeUnits expose the remaining per-call budgets
• CancellationToken enables cooperative cancellation and may be nil
