Processing Methods of the Engine Object
The Engine object exposes a set of processing methods. They are used to open and convert image files or bitmaps, or process an image/PDF file directly. However, using the methods of the FRDocument object is more convenient in most scenarios.
Name | Description |
---|---|
GetNumberOfPagesInImageFile | Returns the number of pages in an image file. |
InjectTextLayer | Processes the input PDF file and creates a searchable PDF file of the "image on text" type which contains the same page images and the text layer created from the recognized text. |
IsPdfPortfolio | Determines if a PDF file is a PDF Portfolio. |
IsPdfPortfolioFromStream | Determines if a PDF file added from the stream is a PDF Portfolio. |
IsPdfWithTextualContent | Determines if any of the pages of a PDF file contains text layer. |
IsPdfWithTextualContentFromStream | Determines if any of the pages of a PDF file added from the stream contains text layer. |
LoadImageDoc | Restores the contents of the ImageDocument object from the folder on disk. |
LoadImageDocFromFile | Restores the contents of the ImageDocument object from the file previously saved with the help of the IImageDocument::SaveToFile method. |
LoadImageDocFromMemory | Restores the contents of the ImageDocument object from the global memory, where it was previously saved by the IImageDocument::SaveToMemory method. |
OpenBitmap | Opens the specified bitmap image (HBITMAP). |
OpenBitmapBits | Opens the specified bitmap data. |
OpenDib | Opens the specified device-independent bitmap. |
OpenImageFileFromMemory | Opens an image file from the global memory, where it was previously loaded by the user. |
PrepareBitmap | Creates a copy of the specified bitmap image (HBITMAP) in FineReader Engine internal image format. |
PrepareBitmapBits | Creates a copy of the specified bitmap data in FineReader Engine internal image format. |
PrepareDib | Creates a copy of the specified device-independent bitmap in FineReader Engine internal image format. |
