Any support helps! This is a very neat feature. If you don't pass in the page attribute, does it create thumbnails of all the pages in the PDF? I think the imagePrefix attribute could be essential where you're doing this for many pdfs; you don't want to create a new folder for each pdf or do you?
Yes, if you don't specify pages, it does them all. But don't forget that if you keep it blank and use a source that points to a filename, CFPDF will use the name for a prefix.
I hadn't noticed the line "unless your source is a PDF file. I have some question May you can help me 1 auto print pdf by user don't click printer icon 2 how to use parmision for print copy i try permision auttibue some time but don't work. You can't force something to print on the client's machine. The first method can be done using javascript in Acrobat. That's pretty interesting. I'm trying now to see if I can do this JS in cfdocument.
So far I've not been successful. Ray, have you done anything with PDF forms yet? You hinted at it in the beginning of the entry Not yet. The books kinda kicked my butt. Now that they are done I'm hoping to get more articles like this out. Thanks for posting the new PDF features in Coldfusion 8. I've learned a lot. If I may, I have a dumb question that I would like to ask because I can't find any help with this If I read you right, my understanding is that you can't control what plugin is used - the browser user controls that.
You can give a hint by using cfcontent, but at the end of the day, the end user decides what to do with your binary data. The code isn't throwing any errors and the PDFs do have content. Any ideas? The remaining thumbnails generated are also all blank except for a small grey line at the bottom which isn't in the PDFs.
In the current application I'm creating, I tried using cfdocument to create a PDF of any file type word, ppt, excel etc. The thumbnail generated for images,word etc was hazy. Thanks for the post Ray. Is there a way to specify the UNIX permissions mode? I noticed that when I started using cfpdf and throwing the output threw cfcontent that the saveAsName attribute in cfdocument becomes worthless and that instead had to revert back to putting the name back to cfheader.
Btw, miss the meetings up at langley with the user group. Glad to see you are making it big time. Anyone have any trouble taking a PDF file and using acrobat 9 standard to reduce file size?

I'm thinking based upon your response that it is going to be better for me to start with html and populate the form based on that, considering I need to also save the data to a database anyway. PatrickSchomburg yes perhaps. If you are working closely with a livecycle designer this can work well, otherwise it's a lot of frustrating trial and error that may never get you what you need.
But again, the pdf has to be deciphered and permisssed to allow it I think. Sathish Chelladurai Sathish Chelladurai 1 1 gold badge 8 8 silver badges 21 21 bronze badges.

The value for rotation must be in steps 0, 90, , If you specify any other value, the system generates an error. Display setting for initial view of the PDF document. Permissions assigned for editing the PDF content. To change this setting, use the permissions attribute with the protect action. Permissions assigned for adding comments to the PDF document. Permissions assigned for extracting content from the PDF document. Permissions assigned for copying content from the PDF document.
System-generated creation date of the PDF document. You can specify a text string with the setInfo action. Specifies whether the PDF file is password-protected. To change the encryption algorithm, or add a password, use the protect action.
Permissions assigned for entering data in form fields. Keywords specified for searches in the PDF document. You can specify a comma-separated list of keywords with the setInfo action.
System-generated timestamp for when the PDF file was last modified. Display setting for the initial view of the PDF document. Permissions assigned for printing the document. Permissions for allowing electronic signatures to the PDF document. Indicates whether trapping is applied to the PDF document. Trapping is used in printing to eliminate gaps between two adjoining ink colors.
To change this setting use the version attribute with the write action. For more information, see the section PDF versions. By default, ColdFusion adds the files in descending order by timestamp. The following code merges the source files in ascending order by filename:. This is useful if the source files have logical names, such as Chap0.
By default, ColdFusion continues the merge process even if it encounters a file in the specified directory that is not a valid PDF document. To stop the merge process if the directory contains files other than valid PDF documents, set the stopOnError attribute to yes:.
To create a PDF file from specific pages in a document, use the source attribute with the pagesattribute. The following code creates a file from pages of the source document:. To merge several files into one document, specify the absolute pathnames of the files in a comma-separated list, as the following code shows:. For more control over the order of files, to assemble files in different locations, and to extract pages from multiple PDF files, use the cfpdfparam tag with the merge action.
The following example shows the DDX instructions for merging several documents and generating a table of contents with bookmarks from the source PDF documents:. The name attribute defines a variable that you use to determine the success or failure of the process. Use the cfoutput tag to display the success or failure message, as the previous example shows, or use the cfdump tag to display a structure:. When you use the protect action, set a newUserPassword or a newOwnerPassword.
You can set both, as long as the passwords differ. When you assign a user password to a document, all users must use this password to open the PDF document. The following code adds a user password to a PDF document:. To set the permissions on the output file, set the newOwnerPassword. A user who enters the owner password when accessing the PDF file is considered the owner of file.
The following example shows how to set a new owner password:. Because the permissions are set to AllowDegradedPrinting in this example, ColdFusion lets users print the document at DPI, but prohibits all other actions. If a user tries to delete the file, for example, ColdFusion generates an error message indicates that the password was entered incorrectly or the permissions do not allow the action to be performed.
ColdFusion does not retain permissions: if you add a newUserPassword attribute, you also must set the permission explicitly. To work with myVar, you specify newownerpw as the password. A PDF document can have two kinds of passwords: a user password and an owner password. The following table describes the two types of ColdFusion passwords and their equivalents in Acrobat:.
Anyone who tries to open the PDF document must enter the password that you specify. A user password does not allow a user to change restricted features in the PDF document.
When you protect a PDF, your password changes to the one you provide. ColdFusion updates the variable's saved password to the one you provide. However, if you provide both passwords, ColdFusion uses the owner password.
The following protects a PDF:. Users can copy text, images, and other file content. This setting is required to generate thumbnail images with the thumbnail action. Users can print the document at high-resolution print-production quality. This setting is required for use with the cfprint tag.
The encrypt attribute sets the type of encryption used for opening a password-protected document. To change the encryption algorithm, use the encrypt attribute with the protect action.
Advanced Encryption Standard AES specifies the Rijndael algorithm, a symmetric block cipher that can process data blocks of bits. This is the highest encryption level. This encryption algorithm lets users do the following:. RC4 bit encryption. This encryption algorithm lets users encrypt the document contents, but not the document metadata. Document metadata is used in Internet searches.
If the metadata is encrypted, search engines cannot search the PDF document. Users running an earlier version of Acrobat cannot open a PDF document with a higher encryption setting. For example, if you specify AES encryption, a user cannot open the document in Acrobat 6. You can specify individual pages within the source document to generate thumbnails. To generate thumbnail images, the permissions of the source document must include AllowCopy.
For more information, see Permissions for PDF documents in cfpdf. If a document contains high-resolution images and you want to retain the resolution of the images, then this attribute is useful.
For example:. As the name of the attribute suggests, it is only valid for the TIFF format. Following is an example:. The following example illustrates the use of maxscale, maxlength, and maxbreadth:.
Note: Typically, the value of the scale attribute is set to when using the maxscale attribute. You can now use either name or destination attributes with the write action. The name attribute takes the value as the PDF document variable. For example, you can write the preceding code snippet as:.
The new encodeall attribute encodes all the unencoded streams in the source. However, it does not discriminate between dumb encodings like LZW and encodings like flate, so only unencoded streams get flateencoded. The following table shows the compatibility between the PDF version and the corresponding Acrobat and Adobe Reader versions:. To linearize PDF documents for faster web display, set the saveOption attribute to linear, as the following code shows:.
Do not use the linear save option if you have to maintain interactivity in PDF forms or if the PDF document is enabled for electronic signatures. To allow for electronic signatures, set the saveOption attribute to incremental, as the following code shows:. ColdFusion does not support flattening forms created in Adobe LiveCycle. The following example generates thumbnail images from pages in a PDF document and links the thumbnail images to the pages in the PDF document:.
It was developed to enable the long-term preservation of electronic documents and provides specifications for the creation, viewing, and printing of PDF documents, with the intent of preserving final documents of record as self-contained documents.
The standard does not define an archiving strategy or the goals of an archiving system. Rather, it identifies a "profile" for a PDF file that makes it possible to reproduce the visual appearance of the document the exact same way in the future. This profile specifies what must be included in the file, while prohibiting features that are not suitable for long-term archiving.
