Watermark display distorted in Acrobat 8 when angle > 0

[Periyannan_Muthaiah@adobeforums.com]

We are adding Watermark to a PDF document with below code. When that doc is opened in Acrobat 7.0 Standard the display is correct. But the same document if opened in Acrobat 8 prof. the WaterMark display location is different and not proper as expected. This happens only if we input angle > 0 in degree param of PDDocAddWatermarkParamsRec.

Kindly let us know why it is happening so and a way to make the display same in both Acrobat7 and Acrobat8.

PDPageRange pdPageRange;
memset(&pdPageRange, 0x00, sizeof(pdPageRange));
pdPageRange.startPage = pWaterMarkObj->lStartPageIdx;
pdPageRange.endPage = pWaterMarkObj->lEndPageIdx;
pdPageRange.pageSpec = PDAllPages;
memset(&objAddWatermarkParamsRec, 0x00, sizeof(PDDocAddWatermarkParamsRec));
objAddWatermarkParamsRec.size = sizeof(objAddWatermarkParamsRec);
objAddWatermarkParamsRec.targetRange = pdPageRange;
objAddWatermarkParamsRec.fixedPrint = FALSE;
objAddWatermarkParamsRec.zOrderTop = FALSE;
objAddWatermarkParamsRec.showOnScreen = TRUE;
objAddWatermarkParamsRec.showOnPrint = TRUE;
objAddWatermarkParamsRec.horizAlign = pWaterMarkObj->eWTMHorziAlign;
objAddWatermarkParamsRec.vertAlign = pWaterMarkObj->eWTMVertAlign;
objAddWatermarkParamsRec.horizValue = (float)pWaterMarkObj->lHorizValue;
objAddWatermarkParamsRec.vertValue = (float)pWaterMarkObj->lVertValue;
objAddWatermarkParamsRec.percentageVals = FALSE;
objAddWatermarkParamsRec.scale = pWaterMarkObj->fScale;
objAddWatermarkParamsRec.rotation = pWaterMarkObj->fRotation;
objAddWatermarkParamsRec.opacity = pWaterMarkObj->fOpacity;
objAddWatermarkParamsRec.progMonData = NULL;
objAddWatermarkParamsRec.cancelProcData = NULL;
objAddWatermarkParamsRec.progMon = NULL;
objAddWatermarkParamsRec.cancelProc = NULL;

What version of Acrobat and what version of the SDK are you using to invoke that code?

[Periyannan_Muthaiah@adobeforums.com]

Acrobat 8.1.2 Prof and SDK version 8

[Leonard_Rosenthol@adobeforums.com]

So then where does Acrobat 7 come in?

[Periyannan_Muthaiah@adobeforums.com]

I am using a Plug In developed with SDK version 8 and inserting the Watermark. If the PDF doc is opened in Acrobat 7 standard the display is correct and in Acrobat 8 prof the display is not proper.
PDF has the same Watermark data but the display is differing.

What change I should do in Plug In code given above, to make both displays same.

Can you post/send me a sample PDF?

It seems a defect in Acrobat 7 - Watermark Position Vertical Horizontal from Top, Center and Bottom is fixed in Acrobat 8 and above. Acrobat 7 displays Text Watermark with 45 degree Vertical 0 Top Horizontal 0 Right in a hidden manner. From Acrobat 8 and above display is OK.

Thank you very much for your great support once again.
