Overview
The operation allows to optimize the PDF document.
Parameters
| Name | Type | Description |
|---|---|---|
| Input | Array | Array of IUnknown-based objects that should contain the IPXC_Document that will be optimized. Note that only the first element from the array will be evaluated.
|
| Output | Array | Array of IUnknown-based objects. Not used.
|
| Options | Dictionary | Dictionary with options of the operation. |
Sample
//C#
private void OptimizeDocument(PDFXEdit.IPXV_Document Doc, PDFXEdit.IPXV_Inst Inst)
{
int nID = Inst.Str2ID("op.document.optimize", false);
PDFXEdit.IOperation Op = Inst.CreateOp(nID);
var input = Op.Params.Root["Input"];
//The document can be optimized only when it's not opened in the Editor Control (it does not have the correspondent IPXV_Document)
PDFXEdit.IAFS_Inst fsInst = (PDFXEdit.IAFS_Inst)Inst.GetExtension("AFS");
PDFXEdit.IAFS_Name impPath = fsInst.DefaultFileSys.StringToName("D:\\TestFile_res.pdf");
//We save it on disk
Doc.CoreDoc.WriteTo(impPath);
PDFXEdit.IPXC_Inst pxcInst = (PDFXEdit.IPXC_Inst)Inst.GetExtension("PXC");
PDFXEdit.IPXC_Document resDoc = pxcInst.OpenDocumentFrom(impPath, null);
//Then pass it to the optimization operation
input.Add().v = resDoc;
PDFXEdit.ICabNode options = Op.Params.Root["Options"];
PDFXEdit.ICabNode images = options["Images"];
images["Enabled"].v = true;
images["ReducedOnly"].v = true;
PDFXEdit.ICabNode comp = images["Comp"];
comp["Color.JPEGQuality"].v = 0;
comp["Grayscale.JPEGQuality"].v = 0;
Op.Do();
//And save the optimized document again to the same file
resDoc.WriteTo(impPath);
}
