GetCount

Gets the number of text zones in the unit.

virtual int GetCount() const

Return value

Returns the number of text zones in the unit.

GetTextZone

Gets the quadrilateral shape of the text zone at the specified index.

virtual int GetTextZone(int index, CTextZone* textZone) const = 0;

Parameters

[in] index The index of the text zone.

[in, out] textZone A pointer to a CTextZone object to receive the text zone.

Return Value

Returns 0 if the operation succeeds, or a nonzero error code if the operation fails.

RemoveAllTextZones

Removes all text zones from the unit.

virtual void RemoveAllTextZones() = 0;

RemoveTextZone

Removes the text zone at the specified index.

virtual int RemoveTextZone(int index) = 0;

Parameters

index The index of the text zone to remove.

Return Value

Returns 0 if the operation succeeds, or a nonzero error code if the operation fails.

AddTextZone

Adds a text zone to the unit.

virtual int AddTextZone(const CTextZone& textZone, const double matrixToOriginalImage[9] =  IDENTITY_MATRIX) = 0;

Parameters

[in] textZone The text zone to add.

[in] matrixToOriginalImage The matrix to original image.

Return Value

Returns 0 if the operation succeeds, or a nonzero error code if the operation fails.

SetTextZone

Sets the text zone at the specified index.

virtual int SetTextZone(int index, const CTextZone& textZone, const double matrixToOriginalImage[9] =  IDENTITY_MATRIX) = 0;

Parameters

[in] index The index of the text zone to set.

[in] textZone The text zone to set.

[in] matrixToOriginalImage The matrix to original image.

Return Value

Returns 0 if the operation succeeds, or a nonzero error code if the operation fails.
