__init__()

convert_document(in_doc: PdfDocument, out_stream: io.IOBase, profile: Profile) → MultiPageDocument

Convert all pages of a PDF document to a rasterized image

Parameters:

• inDoc (PdfDocument) – The input PDF document

• outStream (io.IOBase) – The stream to which the rasterized image is written.

• profile (Profile) –

  The profile defines how the PDF pages are rendered and what type of output image is used. Note that the profile’s image options must support multi-page images (TIFF). For other profiles, the method pdftools_sdk.pdf2_image.converter.Converter.convert_page should be used.

  For details, see pdftools_sdk.pdf2_image.profiles.profile.Profile.

Returns:

The output image document. The object can be used as input for further processing.

Note that, this object must be disposed before the output stream object (method argument outStream).

Return type:

MultiPageDocument

Raises:

• pdftools_sdk.license_error.LicenseError – The license is invalid.

• OSError – Writing to the output image failed.

• pdftools_sdk.unsupported_feature_error.UnsupportedFeatureError – The input PDF is a PDF collection (Portfolio) that has no cover pages.

• pdftools_sdk.unsupported_feature_error.UnsupportedFeatureError – The input PDF contains unrendered XFA form fields. See pdftools_sdk.pdf.document.Document.xfa for more information on how to detect and handle XFA documents.

• pdftools_sdk.generic_error.GenericError – An unexpected failure occurred.

• ValueError – The profile does not support multi-page output.

• pdftools_sdk.processing_error.ProcessingError – The processing has failed.

• StateError – Internal error has occured.

convert_page(in_doc: PdfDocument, out_stream: io.IOBase, profile: Profile, page_number: int) → ImageDocument

Convert a single page of a PDF document to a rasterized image

Parameters:

• inDoc (PdfDocument) – The input PDF document

• outStream (io.IOBase) – The stream to which the rasterized image is written.

• profile (Profile) –

  The profile defines how the PDF page is rendered and what type of output image is used.

  For details, see pdftools_sdk.pdf2_image.profiles.profile.Profile.

• pageNumber (int) – The PDF page number to be converted. The number must be in the range of 1 (first page) to pdftools_sdk.pdf.document.Document.page_count (last page).
