Knowing proper image resolution is important, as it enables the OCR engine to translate pixel heights of characters to their respective font sizes. We do our best to retrieve resolution information from the input's metadata, however it occasionally can be corrupt or missing. Hence we allow manual override of source's resolution, which supersedes any metadata found (both explicit as in image metadata and implicit as in PDF).
- Parameters
-
- Returns
- this object, for call chaining
Adds a collection of ignorable regions for the given page, an optional list of page areas not to be included in analysis
- Parameters
-
regions,: | the zones to be added to the ignore list |
page_num,: | the page number the added regions belong to |
- Returns
- this object, for call chaining
Adds a language to the list of to be considered when processing this document
- Parameters
-
lang,: | the new language to be added to the language list |
- Returns
- this object, for call chaining
Adds a collection of text regions of interest for the given page, an optional list of known text zones that will be used to improve OCR quality
- Parameters
-
regions,: | the zones to be added to the text region list |
page_num,: | the page number the added regions belong to |
- Returns
- this object, for call chaining
bool pdftron::PDF::OCROptions::GetAutoRotate |
( |
| ) |
|
Gets the value AutoRotate from the options object Default value is false. Setting to true will deskew the image before conducting OCR.
- Returns
- a bool, the current value for AutoRotate.
UString pdftron::PDF::OCROptions::GetOCREngine |
( |
| ) |
|
Gets the value OCREngine from the options object Backend engine to use for OCR processing. Options include 'default', 'any', or 'iris'. Chosen module must be present and correctly licensed.
- Returns
- a UString, the current value for OCREngine.
OCROptions& pdftron::PDF::OCROptions::SetAutoRotate |
( |
bool |
value | ) |
|
Sets the value for AutoRotate in the options object Default value is false. Setting to true will deskew the image before conducting OCR.
- Parameters
-
value,: | the new value for AutoRotate |
- Returns
- this object, for call chaining
OCROptions& pdftron::PDF::OCROptions::SetIgnoreExistingText |
( |
bool |
value | ) |
|
Sets the value for IgnoreExistingText in the options object Default value is false, so that areas with existing text will be automatically skipped during OCR. Setting to true probably only makes sense when used with GetOCRJson/XML, as pre-existing text might end up being duplicated in the document when used with ImageToPDF and ProcessPDF.
- Parameters
-
value,: | the new value for IgnoreExistingText |
- Returns
- this object, for call chaining
Sets the value for OCREngine in the options object Backend engine to use for OCR processing. Options include 'default', 'any', or 'iris'. Chosen module must be present and correctly licensed.
- Parameters
-
value,: | the new value for OCREngine |
- Returns
- this object, for call chaining
OCROptions& pdftron::PDF::OCROptions::SetUsePDFPageCoords |
( |
bool |
value | ) |
|
Sets the value for UsePDFPageCoords in the options object Sets origin of the coordinate system for input/output
- Parameters
-
value,: | If true, sets origin of the coordinate system for input/output to the bottom left corner and reverses the direction of y-coordinate axis from downward to upward, otherwise top left corner is used as the origin and the y-coordinate axis direction is downward |
- Returns
- this object, for call chaining
