gstate. Within a PDEForm, each PDEElement has its own gstate (or is a container, place, or group object). These gstates are independent of the parent PDEForm gstate. PDEForm elements within the PDEForm may have their own opacity. A PDEContent may be obtained from a PDEForm to edit the form's display list. typedef struct _t_PDEForm *PDEForm; Acquires the transparency group dictionary of the XObject form.
Call PDERelease() to dispose of the PDEXGroup when finished with it.
PDEXGroup PDEFormAcquireXGroup(IN PDEForm pdeForm); pdeForm | IN/OUT The from.

Creates a new form from an existing form object. Creates a copy of the PDEForm, including the underlying CosStream.
Call PDERelease() to dispose of the returned PDEForm object when finished with it.
PDEForm PDEFormCreateClone(IN PDEForm form); form | The form object from which a new PDEForm is created.
|
Superseded by PDEFormCreateFromCosObjEx() in Acrobat 10.0. Creates a new form from an existing Cos object.
Call PDERelease() to dispose of the returned form object when finished with it.
PDEForm PDEFormCreateFromCosObj(IN const CosObj *xObjectP, IN const CosObj *resourcesP, IN ASFixedMatrixP matrixP); xObjectP | The Cos object from which a PDEForm is created.
|
resourcesP | The
xObjectP parameter's Resources dictionary. If you do not pass in a Resource object, subsequent calls to PDPageAcquirePDEContent() will fail (after the file is saved). |
matrixP | A pointer to an ASFixedMatrix that holds the transformation matrix to use for the form.

Note: Unlike other GetContent methods, this method does increment the reference count of the returned PDEContent. Call PDERelease() to dispose of the returned PDEContent object when finished with it.
PDEContent PDEFormGetContent(IN PDEForm form); form | The form whose content is obtained.
|
form. PDEContentToCosObjFlags for this form. The flags were previously set by PDEFormSetContentToCosObjFlags(). ASUns32 PDEFormGetContentToCosObjFlags(IN PDEForm form); void PDEFormGetCosObj(IN PDEForm form, OUT CosObj *cosObjP); form | IN/OUT The form whose Cos object is obtained.

ASDouble PDEFormGetLeading(IN PDEForm form); form | IN A form XObject object.
|
Superseded by PDEFormGetMatrixEx() in Acrobat 10.0. Gets the matrix for a PDEform.
The result is a concatenation of the CTM and the Cos level form matrix, resulting in the transformation from the form space to the device space.
Note: For the other elements, PDEElementGetMatrix() would give correct results.
void PDEFormGetMatrix(IN PDEForm form, OUT ASFixedMatrixP matrixP); form | The form for which the matrix is required.
|
matrixP | The resultant matrix.
