TPdfToolsPdfAConversion_Converter_ConversionEventA

typedef void(PDFTOOLS_CALL * TPdfToolsPdfAConversion_Converter_ConversionEventA) (void *pContext, const char *szDataPart, const char *szMessage, TPdfToolsPdfAConversion_EventSeverity iSeverity, TPdfToolsPdfAConversion_EventCategory iCategory, TPdfToolsPdfAConversion_EventCode iCode, const char *szContext, int iPageNo)

The event for errors, warnings, and informational messages that occur during conversion.

Report a conversion event that occurred in PdfToolsPdfAConversion_Converter_Convert. These events can be used to:

• Generate a detailed conversion report.
• Detect and handle critical conversion events.

Note that if a document cannot be converted to the requested conformance, the PdfToolsPdfAConversion_Converter_Convert throws an exception. However, even if the output document meets all required standards, the conversion might have resulted in differences that might be acceptable in some processes but not in others. Such potentially critical conversion issues are reported as conversion events.

We suggest checking which conversion events can be tolerated in your conversion process and which must be considered critical:

• Review the suggested severity of events. Each event has a default severity indicated by severity which is based on the event's category. Review the suggested severity of each TPdfToolsPdfAConversion_EventCategory and determine the TPdfToolsPdfAConversion_EventSeverity to be used in your process.
• Handle events according to their severity.
  • Events of severity ePdfToolsPdfAConversion_EventSeverity_Error: The conversion must be considered as failed.
  • Events of severity ePdfToolsPdfAConversion_EventSeverity_Warning: In case of a warning, the output file is best presented to a user to decide if the result is acceptable. The properties message, context, and page in combination with the output file are helpful to make this decision. If a manual review is not feasible, critical warnings should be classified as an ePdfToolsPdfAConversion_EventSeverity_Error. An exception to this is, if all processed input documents are similar in their content, e.g. because they have been created by a single source (application). In this case, the conversion result can be verified using representative test files and the event severity chosen accordingly.
  • Events of severity ePdfToolsPdfAConversion_EventSeverity_Information: No further action is required.

Parameters

[in,out]	pContext	Context of the event callback.
[in]	szDataPart	The data part is NULL for the main file and a data part specification for embedded files. Examples: embedded-file:file.pdf: For a file file.pdf that is embedded in the main file. embedded-file:file1.pdf/embedded-file:file2.pdf: For a file file2.pdf that is embedded in an embedded file file1.pdf.
[in]	szMessage	The event message
[in]	iSeverity	The suggested severity of the event. We suggest checking, which conversion events are tolerable in your conversion process and which must be considered critical. See the documentation of TPdfToolsPdfAConversion_Converter_ConversionEvent for a more detailed description.

[in]	iCode	The code identifying particular events which can be used for detection and specialized handling of specific events. For most applications, it suffices to handle events by category.
[in]	szContext	A description of the context where the event occurred
[in]	iPageNo	The page this event is associated to or 0

PdfToolsPdfAConversion_ConversionOptions_GetConformance()

PDFTOOLS_EXPORT BOOL PDFTOOLS_CALL PdfToolsPdfAConversion_ConversionOptions_GetConformance	(	TPdfToolsPdfAConversion_ConversionOptions *	pConversionOptions,
		TPdfToolsPdf_Conformance *	pConformance )

The minimal target conformance.

If a conformance is set, it is used as the minimal target conformance. The PDF/A version of the conformance must match the PDF/A version of the analysisOptions of PdfToolsPdfAValidation_Validator_Analyze. If the conformance level cannot be achieved, the conversion will abort with the error ePdfTools_Error_Conformance. If a higher conformance level can be achieved, it is used automatically.

If NULL is used, the optimal conformance determined in the analysis (i.e. PdfToolsPdfAValidation_AnalysisResult_GetRecommendedConformance) is used. It is highly recommended to use NULL.

Default value: NULL

Parameters

[in,out]	pConversionOptions	Acts as a handle to the native object of type TPdfToolsPdfAConversion_ConversionOptions.
[out]	pConformance	Retrieved value.

Returns

FALSE if either an error occurred or the [out] argument returns NULL. To determine if an error has occurred, check the error code as described in the note section below.

Note

An error occurred when FALSE was returned and the error code returned by PdfTools_GetLastError is different from ePdfTools_Error_Success. Get the error message with PdfTools_GetLastErrorMessage.

PdfToolsPdfAConversion_ConversionOptions_GetCopyMetadata()

PDFTOOLS_EXPORT BOOL PDFTOOLS_CALL PdfToolsPdfAConversion_ConversionOptions_GetCopyMetadata

(

TPdfToolsPdfAConversion_ConversionOptions *

pConversionOptions

)

Whether to copy metadata Copy document information dictionary and XMP metadata. Default: TRUE.

Parameters

[in,out]

pConversionOptions

Acts as a handle to the native object of type TPdfToolsPdfAConversion_ConversionOptions.

Returns

Retrieved value.

May indicate an error in certain scenarios. For further information see the note section below.

Note

PdfToolsPdfAConversion_ConversionOptions_GetImageQuality()

PDFTOOLS_EXPORT double PDFTOOLS_CALL PdfToolsPdfAConversion_ConversionOptions_GetImageQuality

(

TPdfToolsPdfAConversion_ConversionOptions *

pConversionOptions

)

Image quality of recompressed images.

The image quality for images that use a prohibited lossy compression type and must be recompressed. Supported values are 0.01 to 1.0. A higher value means better visual quality at the cost of a larger file size. Recommended values range from 0.7 to 0.9.

Example: JPX (JPEG2000) is not allowed in PDF/A-1. If a PDF contains a JPX compressed image, its compression type must be altered. Thus the image is converted to an image with JPEG compression using the image quality defined by this property. Copy document information dictionary and XMP metadata. Default value: 0.8

Parameters

[in,out]

pConversionOptions

Acts as a handle to the native object of type TPdfToolsPdfAConversion_ConversionOptions.
