Methods

CancelConversion()

Cancel the current conversion, forcing TryConvert or Convert to return.

Declaration

public void CancelConversion()

Convert()

Perform the conversion. Will throw an exception on failure.

Declaration

public void Convert()

ConvertNextPage()

Perform the conversion. Will throw an exception on failure. Does nothing if the conversion is already complete. Use GetConversionStatus() to check if there is remaining content to be converted.

Declaration

public void ConvertNextPage()

Dispose()

Declaration

public override sealed void Dispose()

Dispose(Boolean)

Declaration

protected void Dispose(bool A_0)

Parameters

Type	Name	Description
System.Boolean	A_0

GetConversionStatus()

Get the state of the conversion process. Pair this with ConvertNextPage().

Declaration

public DocumentConversionResult GetConversionStatus()

Returns

Type	Description
DocumentConversionResult

GetDoc()

Gets the PDFDoc from the conversion. Can be accessed at any time during or after conversion.

Declaration

public PDFDoc GetDoc()

Returns

Type	Description
PDFDoc	The conversion's PDFDoc

GetErrorString()

If the conversion finsihed with some kind of error, this returns the value of the the error description ()otherwise returns an empty string.

Declaration

public string GetErrorString()

Returns

Type	Description
System.String	The error description. Will be blank unless GetConversionStatus returns Failure

GetNumConvertedPages()

Returns the number of pages which have been added to the destination document. Will never decrease, and will not change after the conversion status becomes "complete".

Declaration

public int GetNumConvertedPages()

Returns

Type	Description
System.Int32	The number of pages that have been converted

GetNumWarnings()

Return the number of warning strings generated during the conversion process. Warning: experimental interface; this method may be renamed or replaced with equivalent functionality in the future.

Declaration

public int GetNumWarnings()

Returns

Type	Description
System.Int32	The number of stored warning strings

GetProgress()

Returns a number from 0.0 to 1.0, representing the best estimate of conversion progress. This number is only an indicator, and should not be used to dictate program logic (in particular, it is possible for this method to return 1.0 while there is still work to be done. Use GetConversionStatus() to find out when the conversion is fully complete).

Declaration

public double GetProgress()

Returns

Type	Description
System.Double	The conversion progress. Will never return a smaller number than a previous call

GetProgressLabel()

Returns the label for the current conversion stage. May return a blank string. Warning: experimental interface; this method may be renamed or replaced with equivalent functionality in the future.

Declaration

public string GetProgressLabel()

Returns

Type	Description
System.String	The stage label

GetWarningString(Int32)

Retrieve warning strings that have been collected during the conversion process. Warning: experimental interface; this method may be renamed or replaced with equivalent functionality in the future.

Declaration

public string GetWarningString(int index)

Parameters

Type	Name	Description
System.Int32	index	the index of the string to be retrieved. Must be less than GetNumWarnings()

Returns

Type	Description
System.String	The value of the particular warning string

HasProgressTracking()

Determine whether this DocumentConversion has progress reporting capability.

Declaration

public bool HasProgressTracking()

Returns

Type	Description
System.Boolean	True if GetProgress is expected to return usable values

IsCancelled()

Has the conversion been cancelled?.

Declaration

public bool IsCancelled()

Returns

Type	Description
System.Boolean	Returns true if CancelConversion has been called previously

TryConvert()

Perform the conversion. If the result of the conversion is failure, then GetErrorString will contain further information about the failure.

Declaration

public DocumentConversionResult TryConvert()

Returns

Type	Description
DocumentConversionResult	Indicates that the conversion succeeded, failed, or was cancelled
