AddImageWatermark and AddTextWatermark for API

Post by kmoens » Fri Apr 13, 2012 3:46 pm

I downloaded the latest PDF-XChange PRO 4 sdk
which was the PDFSDKPRO4.zip file.

I openned the VbExCom vb6 project and modified the code to use the AddImageWatermark and AddTextWatermark based on other examples seen earlier. I didn't see either of the watermarks added to the PDF.

The code is below. Let me know why the Watermarks are not there.

Regards,
Kevin

Has anyone been able to reproduce this issue?

This is for a customer that we are upgrading from PDF X-Change 3.0 to 4.0. I am just looking to get this going.

Hi Kevin,

not wishing to be pedantic - but looking through code is never easy and you quickly become 'code blind' - a small working example is a far better way to proceed and will elicit a quicker answer - please provide a simple example that displays the issue - both project source and compiled and zip and send - if you wish to leave you license info in the example - PLEASE DO NOT POST HERE - please send to support@tracker-software.com with a link back to this forum post.

Once we have we wil take a look as soon as possible
If posting files to this forum - you must archive the files to a ZIP, RAR or 7z file or they will not be uploaded - thank you.

Best regards
Tracker Support

I attached VbExCOM.zip.
This contains the source and compiled VB6 example into a zip file.

Below are the lines added that are not in the basic demo:

PDFPrinter.Option("Watermarks.Enabled") = "Yes"
PDFPrinter.AddImageWatermark "I", "P:\DOCTRAK FORMS\temp\Lake\Older Stuff\LAKOrderVerification.bmp", -1, 210, 297, 17, 0, 0, 0, 50, 796, 0, ""
PDFPrinter.AddTextWatermark "T", "TEST", "Arial", 0, 0, 0, 0, 0, 0, 17, 0, 0, 0, 50, 28, 0, ""
PDFPrinter.Option("Watermarks.Watermarks") = "I;T"
PDFPrinter.ApplyOptions 0

It looks like you have set the flags argument to "796" in the image watermark case, binary 1100011100... I'm not sure what the high bits are intended to do here but they will probably be ignored... however, since the second last bit is not set it will not be visible in the viewer. I just noticed there's an error in the documentation (flags offset by one) and it will be fixed shortly. Set flags to decimal 14 (binary 1110) to set all bits except background. The flags are binary 1 for placement in background, 10 for viewer, 100 for export visibility, and 1000 for printing visibility...

Same problem with the flags for the text watermark: should be 14 (binary 1110), not 28 (binary 11100). I will get this documentation typo fixed ASAP.

Also, in the text case, you are using a font weight of zero. It should be 400 for normal and 700 for bold.

Font size is also set to zero; this may be intentional (font will be adjusted to fit entire page), but it may be an oversight you will want to fix as well. dwAlign is set to 17, but because font size is zero this will be ignored and interpreted as horizontal & vertical centering (value 9).

Can you advise if the documentation has been updated now, and if so what the date and/or version number are?

The version of PDFX4DRV_API.pdf that I'm using is dated 15/04/2008 (in the PDF properties) and it seems to contain numerous mistakes.

If there's an updated version can you please give me a link to it?

Thanks

Hi Stefan

While you're waiting on a response from "the guys maintaining the manuals", can you please advise what is the latest version of documentation that you have access to?

I really hope that it has been updated since 2008.

Thanks

Hi David,

The attached copy is from 14 Feb this year, though I can't tell what the changes in it are.

I updated making the changes you suggested and then I also included the bitmap I am testing with. I still do not see these watermarks.

I uploaded the zip file with the changes.

Code: Select all

 PDFPrinter.AddImageWatermark "I", "P:\DOCTRAK FORMS\temp\Lake\Older Stuff\LAKOrderVerification.bmp", -1, 210, 297, 17, 0, 0, 0, 50, 796, 0, ""

The syntax for this function is:

Code: Select all

Sub AddImageWatermark(
sName As String,
sImageFileName As String,
dwTranscolor As Long,
dwWidth As Long,
dwHeight As Long,
dwAlign As Long,
xOffset As Long,
yOffset As Long,
nAngle As Long,
dwOpacity As Long,
dwFlags As Long,
dwPlaceType As Long,
sRange As String)
In your example you have:

dwTranscolor = -1
dwWidth = 210
dwHeight = 297
dwAlign = 17
xOffset = 0
yOffset = 0
nAngle = 0
dwOpacity = 50
dwFlags = 796
dwPlaceType = 0
sRange = ""

Can you do as I originally suggested and change dwFlags to 14?

You have also not made the changes I suggested to AddTextWatermark, for flags and font weight.

(Also, this is an unrelated issue that will make your life easier, if you set variables with sensible names and pass those to the function it will make your coding life much easier, so you can see what each argument is set to instead of just seeing a long list of values. ie, PDFPrinter.AddTextWatermark(name, content, font, ...))..

Sorry about that... the VB6 app died and lost the changes. So I zipped up the wrong code. Re-made the changes and retested still with no luck.

Please try placing each watermark (text, and then image) in isolation to help narrow down which one might be causing the problem.

It could be something as simple as failing to load the image from disk (e.g. incorrect path).

In the last zip file I uploaded I moved the bitmap next to the executable path.

Everything should be in the zip file for you to test.

I am looking to make an ImageWatermark act like an overlay with an RGB value of (244, 244, 244) as the Transparent Color.

With PDF X-Change 3.0 we put these setting in the Printing Preferences - Watermarks area.

I am not concerned with the TextWatermark as much.

Hi, I have been unable to build your VB6 project - however I will still do my best to help you.

Could you try adding only a single watermark, using the same image. If this fails, try to do the same with a different image and see if this works?

I did my tests. 14 as your suggestion still kept the Background Flag checked
0001 = ?
0010 = Background
0100 = View
1000 = Export
1 0000 = Print 


I also found out when I used single Character names such as "I" for Image and "T" for Text it wouldn't select the watermark.

Attached is a word doc holding screen shots of the tests I tried.

Is there a way to set the flag "Fit To Page"?

Hello kmoens,

Seems like the Screenshots you wanted to attach two posts above went missing - you will need to zip them before uploading.

As for the FitPage - you need to set General.MagnificationType to 2 (FitPage).

Best,
Stefan
