how to add:

AVDoc avDoc = AVAppGetActiveDoc();
PDDoc pdDoc = AVDocGetPDDoc(avDoc);

ASText astextSrcText = ASTextFromScriptText("WATERMARK",
kASRomanScript);

PDColorValueRec pdColorValue;
memset(&pdColorValue, 0x00, sizeof(pdColorValue));
pdColorValue.space = PDDeviceRGB;
pdColorValue.value[0] = fixedZero;
pdColorValue.value[1] = fixedZero;
pdColorValue.value[2] = fixedOne;

PDDocWatermarkTextParamsRec pdDocWatermarkTextParamsRec;
memset(&pdDocWatermarkTextParamsRec, 0x00,
sizeof(pdDocWatermarkTextParamsRec));
pdDocWatermarkTextParamsRec.size = sizeof(PDDocAddWatermarkParamsRec);
pdDocWatermarkTextParamsRec.srcText = astextSrcText;
pdDocWatermarkTextParamsRec.textAlign = kPDHorizCenter;
pdDocWatermarkTextParamsRec.pdeFont = NULL;
pdDocWatermarkTextParamsRec.sysFontName = ASAtomFromString("Arial");
pdDocWatermarkTextParamsRec.fontSize = 22.0f;
pdDocWatermarkTextParamsRec.color = pdColorValue;

// header/footer will be added to every page
PDPageRange pdPageRange;
memset(&pdPageRange, 0x00, sizeof(pdPageRange));
pdPageRange.startPage = 0;
pdPageRange.endPage = PDDocGetNumPages(pdDoc) - 1;
pdPageRange.pageSpec = PDAllPages;

PDDocAddWatermarkParamsRec pdDocAddWatermarkParamsRec;
memset(&pdDocAddWatermarkParamsRec, 0x00,
sizeof(pdDocAddWatermarkParamsRec));
pdDocAddWatermarkParamsRec.size = sizeof(PDDocAddWatermarkParamsRec);
pdDocAddWatermarkParamsRec.targetRange = pdPageRange;
pdDocAddWatermarkParamsRec.fixedPrint = true;
pdDocAddWatermarkParamsRec.zOrderTop = true;
pdDocAddWatermarkParamsRec.showOnScreen = true;
pdDocAddWatermarkParamsRec.showOnPrint = false;
pdDocAddWatermarkParamsRec.horizAlign = kPDHorizCenter;
pdDocAddWatermarkParamsRec.vertAlign = kPDVertCenter;
pdDocAddWatermarkParamsRec.horizValue = 0.0f;
pdDocAddWatermarkParamsRec.vertValue = 0.0f;
pdDocAddWatermarkParamsRec.percentageVals = false;
pdDocAddWatermarkParamsRec.scale = 1.0f;
pdDocAddWatermarkParamsRec.rotation = 0.0f;
pdDocAddWatermarkParamsRec.opacity = 1.0f;
pdDocAddWatermarkParamsRec.progMonData = NULL;
pdDocAddWatermarkParamsRec.cancelProcData = NULL;
pdDocAddWatermarkParamsRec.progMon = NULL;
pdDocAddWatermarkParamsRec.cancelProc = NULL;
PDDocAddWatermarkFromText(pdDoc, &pdDocWatermarkTextParamsRec,
&pdDocAddWatermarkParamsRec);

ASTextDestroy(astextSrcText);
