PDF Underlay option in PDF Stamp

2011/07/162011/07/16

I am trying to get the text to appear as an underlay to be a watermark, the manual says:

-L : (default is top most of all layers, overlay)

Use the -L parameter to stamp under the existing text and/or graphics of the input PDF document; the default is top most of all layers.

I am passing the following:-

-AT Copy -fs10 -p5 -p9 -fn200 -r-45 -c13684944 -fs48 -1 -fn301

If I add a –L then the watermark does appear at all, I just require the word Copy in grey as an underlay

===========================

You can add “-opacity” parameter to try again, the “-opacity” parameter will add watermark with opacity to your PDF pages, for example,

pdfstamp.exe -PDF "example.pdf" -o "opacity.pdf" -AT "VeryPDF Opacity" -FT "Arial" -P9 -FS100 -opacity50 -C#FF0000 -AI logo.jpg -opacity80 -P2 -AL -LW30 -opacity30 -LINEEX 100,100,200,200

-AT Copy -fs10 -p5 -p9 -fn200 -r-45 -c13684944 -fs48 -1 -fn301 -opacity50

how to make use of EncrptPDF at ASP Application Server Level?

2011/07/16

Please let advice how to make use of EncrptPDF at ASP Application Server Level ( Usable in Background Jobs).

================================

Hi,

Please refer to following information about how to call EncryptPDF SDK from ASP code,

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The EncryptPDF COM for asp user manual

Steps:

1.Copy the encryptpdf.dll and EncryptPDFOCX.dll files to your system32 directory, for example,

~~~~~~~~~~~

copy encryptpdf.dll c:\windows\system32

copy EncryptPDFOCX.dll c:\windows\system32

~~~~~~~~~~~

2.Register the EncryptPDFOCX.dll library in your system, for example,

~~~~~~~~~~~

regsvr32 c:\windows\system32\EncryptPDFOCX.dll

~~~~~~~~~~~

3.Put the test.asp file into your "C:\wwwhome" directory,

5.Run the MS IE software, input http://127.0.0.1 site, and open the "test.asp" file,

6.The result files are generated in the "C:\wwwhome" directory.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Please refer to the ASP code at below,

dim oTest

dim very_ID

dim ret

Set oTest = Server.CreateObject("EncryptPDFOCX.CEncryptPDF")

Response.write "Create Object Success!"

very_ID=oTest.veryEncryptPDFEx("C:\wwwhome\test1.pdf","C:\wwwhome\test1_encrypted.pdf",128,4,"Owner","User")

if very_ID < 0 then

Response.write "Convert Failer!"

Response.write very_ID

else

Response.write "Convert Success!"

end if

Hello, on of our customers asked a question that we could not answer about PDF bookmarking. If we have a multi-page PDF for release and the PDF contains multiple sub-folders, can we release that PDF and have it bookmarked on each sub-section? If so, how do we do that?

=================================

Sorry, we don't understand your meaning for the "PDF contains multiple sub-folders"? do you mean that one PDF file contain all image files which come from multiple sub-folders? If yes, you can add the bookmark for each page without any problem, please refer to following sample code,

void AddTIFFImage(long id)

{

char szImageFile[256];

GetModulePath(szImageFile,"multipage.tif");

//add bookmark

int parentBookmark = pVerySetFunction(id, Very_Set_BookMark, 0, 0,"bookmark one",0);

//get multi page tiff page nums

int pagenum=pVeryGetFunction(id,Very_Get_ImagePageCount,0,0,szImageFile,0);

if(pagenum>4)

{

//set multi page tiff convert

int beginpage=2;

int pagenums=2;

pVerySetFunction(id,Very_Set_MultiPage,beginpage,pagenums,0,0);

}

if(pagenum)

pVeryAddImage(id,szImageFile);

}

What are the recommended PCL and PS drivers that work well with verypdf conversion utility?

2011/07/16

Could you please tell us:

1. What are the formats that are supported by the existing PCL to PDF Converter and PS to PDF Converter utilities?

2. What are the recommended PCL and PS drivers that work well with verypdf conversion utility?

=========================================

1. Our PCL to PDF Converter product does support STANDARD PCL5e, PCL5c, PCL-XL formats, if your printer driver does change the PCL format itself, it will generate non-standard PCL format, our PCL to PDF Converter product may not render non-standard PCL format properly, please notice this matter.

Our PS to PDF Converter has same condition, it is support standard Postscript (Postscript Level 2 and Postscript Level 3) format too.

2. We are always use following PCL and PS drivers, our PCL to PDF Converter and PS to PDF Converter products are support PCL and PS files properly which created by following printer drivers,

"HP Color LaserJet 4550 PCL"

"HP Color LaserJet 4550 PS"

you can install these printer drivers in your system easily.

What is PCL3GUI format?

2011/07/16

Does anybody know, what is the difference between PCL3GUI and normal PCL3? I've searched everywhere in Web, but did not found the details about PCL3GUI Technical Reference and "Command Set" list. So far as I know, PCL3GUI is for bitmap data only but use different compression methods to compress the bitmap data, bitmap headers or something else, PCL3GUI is an extended format to PCL3, but what is the extension to the PCL3? Anybody can tell me?

============================================

PCL3GUI is utilized on HP PHOTOSMART and a few DESKJET drivers. The large distinction is mode 10 compression of images. This is line by line compares with the capacity to jink left and right a few pixels.

VeryPDF company has technology to convert documents to PCL5e, PCL5c, PCL-XL and PCL3GUI formats.

Differences between PCL 5/6 and PCL 3

	PCL 5/ 6	PCL 3
1	Prints complex graphical images in standard memory	To print out some graphical data, the printer needs a faster image processing printer language like PCL3GUI or High Performance Architecture.
2	Object-based language used to describe images. Many objects such as squares, rectangles, lines, arcs, circles and etc can be defined by object-based language. Benefit: For these objects, the image can be described using less data than the corresponding pixel description used in PCL3GUI.	Pixel-based printer language that primarily describes images by pixel. For the same objects like square, rectangles, etc, more data is required. Although bitmaps and other complicated picture type objects use object based language, they are still described in pixels because of their complexity.
3	PCL 5/6 supports downloadable fonts as well as scalable fonts. It also has better capability to rasterize the image compared to the GL2 driver.	Does not support downloadable or scalable fonts
4	Conversion time from EMF to the PCL5/6 object data is less. This reduces the CPU time required. Users have all of the resources of the computer available to them more quickly after starting a print job.	For most EMF object and images, it takes more Central Processing Unit (CPU) bandwidth to convert the EMF to the PCL3GUI pixel data.
5	PCL5/6 printers need more printer memory or at times printer hard disk to rasterize the fonts/images in printer instead of computer system.	The PCL3GUI driver, in general, will use more memory on the computer than the PCL5/6 drivers when creating the RAW data files. PCL3GUI printers appear as a less expensive overall printing solution as the initial purchase price is usually less compared to the PCL5/6 printers. This is because they require less memory RAM and less processing power on each printer.
6	In a network environment, a print server can efficiently control more PCL5/6 printers than PCL3GUI printers. Generally, PCL5/6 printers with higher print speed are for network-enabled printers	When using a client/server use model where print jobs are sent from the client to the server and formatted on the server, the more the users share a fixed bunch of personal printers networked together using the same server, the slower the performance.

PCL3 is in fact a subset of PCL3GUI. You can find numerous variations of PCL3, PCL3c, PCL3c+, PCL3e, and so on. HP does not supply developers with the complete technical specifications of their printers like they did in the previous. And, you may locate numerous versions of PCL3GUI.HP normally mislabels there emulations. They are planning to say "PCL3" in revenue literature and "PCL3GUI" in technical literature. They even have a new printer that is "PCL5" or "PCL5e" (depending on which item or literature you read. But, the emulation around the printer isn't FROM HP, but a 3rd part. And, it doesn't emulate PCL5/5e the best way HP printers did.

In the event you would prefer to learn the details, please directly contact me at support@verypdf.com. We've software to process PCL files to you, we may also provide a suitable "workaround".
