Overview
The operation allows to transform the required content items.
Parameters
| Name | Type | Description |
|---|---|---|
| Input | Array | Array of IUnknown-based objects containing the IPXC_Document which content items will be transformed.
|
| Output | Array | Not yet implemented. |
| Options | Dictionary | Dictionary with options of the operation. |
Sample
//C#
private void TransformContentItems(PDFXEdit.IPXV_Document Doc, PDFXEdit.IPXV_Inst Inst)
{
//Creating contentItems.delete operation
int nID = Inst.Str2ID("op.contentItems.transform", false);
PDFXEdit.IOperation Op = Inst.CreateOp(nID);
var input = Op.Params.Root["Input"];
input.Add().v = Doc.CoreDoc;
PDFXEdit.ICabNode options = Op.Params.Root["Options"];
int nSelID = Inst.Str2ID("selection.contentItems", false);
uint nPage = 0; //Page number that will have it's content items deleted
//First we need to create content items selection
PDFXEdit.IPXV_ContentItemsSelection itSel = (PDFXEdit.IPXV_ContentItemsSelection)Doc.CreateStdSel((uint)nSelID);
//Then we need to get root item entry for the desired page (we'll create it if needed)
PDFXEdit.IPXV_ContentItemEntry itEntry = itSel.GetSel(nPage, true);
//Inserting needed content items from the page
var content = Doc.CoreDoc.Pages[nPage].GetContent(PDFXEdit.PXC_ContentAccessMode.CAccessMode_WeakClone);
for (uint i = 0; i < content.Items.Count; i++)
{
//For example we will take all of the text items
if (content.Items[i].Type == PDFXEdit.PXC_CIType.CIT_Text)
itEntry.Insert(i);
}
//Adding selected page's root entry with added content items to the operation
options["Entries"].Add(PDFXEdit.CabDataTypeID.dt_IUnknown).v = itEntry;
//Specifying the transformation matrix
options["Matrix.a"].v = 0.8;
options["Matrix.b"].v = 0.6;
options["Matrix.c"].v = -0.6;
options["Matrix.d"].v = 0.8;
options["Matrix.e"].v = 0;
options["Matrix.f"].v = 0;
//Transforming content items
Op.Do();
//Clearing the selection
itSel.Clear();
}
