Saving digital signature as a Bitmap Image

HI,
Can we save a digital signature as bitmap in our local drive? If so, the process for the same would be a lot helpful.
Thanks,

Digital Signature Not Showing Up in Saved PDF

I am frequently sent pdf contracts that need to be filled out, signed and returned. I turn the pdf into a form and then add a signature field, click "certify with visible signature," sign it and save it as a pdf. But then when I email the signed pdf it has all the form content but doesn't show the signature. Same for when I open the file in Preview. The signature only shows up in Acrobat. Can anyone help explain what I am doing wrong?
Thanks in advance.

Hi,
It was dsaks who originally asking about creating a digital signature and that's what the core of this thread is about. When Mobius Strip asked about flattening the signature into a bitmap image that I suggested using a custom signature appearance, because the progenitor of the thread was asking about digital signatures. If they can get by with using a custom stamp then that's fine by me, but that wasn't the thread topic.
On to your questions:

I understand why Adobe won't (if that's the case) license the digital signatures ability so that Preview and other applications can use it. However, it should be trivial to allow that wet ink signature appear in other apps and I don't see a compelling reason to prevent it -- afer all, it's not a digital signature.
There is no licensing involved here. The PDF specification is public and the Acrobat SDK even has an example of how to create your own signature plug-in. When it comes to the actual cryptographic operations we license the software from RSA. As far as how the signature is created, and how it should be processed, that's all covered by public facing documentation. In fact, Apple is more than capable of processing signatures using their Keychain utility, it's just that they have elected not to include that functionality into Preview.
If your job is to monitor this forum and assist users, why couldn't you manage to suggest that the other users use the stamps feature, since it was clear that what they were wanting was only the signature image? These folks are spending hundreds and thousands of dollars on your products and they deserve better than this.
It's not my job to monitor the forum. I chime in on digital signature issues because it's a complex subject and there are so few people who understand the minutia of how they work. If dsaks hadn't added "certify with visible signature," to the original post I would have skip this completely, but he/she did so I tried to answer their question.
Finally, it's a bit disingenuous when you stated "The image does not display at all, except in Acrobat/Acrobat Reader". It just doesn't display in the free Mac Preview app. There are other third party signature handlers that will process and display a digital signature in a PDF file, but there are not a lot of them in free PDF viewers. As I said above, if dsaks can get by with a custom stamp then great, but if he/she needs a cryptographically sound digital signature then there is no reason why not to created it because everyone can get the free Reader for the Mac, Windows and Linux platforms.

Multiple Digital Signatures in Adobe Acrobat XI - PDF locks after first signature is saved

I am working with a fillable pdf that was set up by an administrator to have multiple DIGITAL ID/SIGNATURES inputted, i.e. it does not allow images of signatures or text; when you click on the signature field, it ONLY prompts the insertion of a Digital ID. This form requires multiple signatures and editing/text from diverse people. I need to sign it and then circulate it to these other people. For some reason, when I insert the first digital ID and save it, the pdf becomes locked - it is no longer fillable, and no one else can edit or even insert their own signatures. What can I do to allow editing/additional signatures to be inputted after putting in my signature and saving the document? PLEASE HELP.

I don't know where I could post it...Could you please tell me how I might check if signature fields are set to "read only" or not? I have been looking through this pdf for so long and I don't even see the option to do that. When I click on the signature field, it just prompts me to insert the digital signature...there isn't much information displayed at all.

Mac OS 10.5.8 update combined can't be saved, Apple digital signature incorrect.

Hi,
I have tried, several times, to update OS 10.5.1 to 10.5.8 using Apple's online software updater. It takes 20 minutes to download the 768 mb package but then
refuses to save with the following message. 2.16 GHz + 2 GB ram.
Mac OS X can't be saved. The digital signature for this package is incorrect. The package may have been tampered with or corrupted since being signed by Apple.
I need to update to 10.5.8 so I can then install 10.6 etc.
I have tried to install 10.6 without updating to 10.8 but it shows the message: Mac OS X can't install on this computer. I assume this is because I have not, and
cannot, updated to 10.5.8.
Any help would be appreciated.
Apple want me to pay $20 to advise them that their software package has an incorrect digital signature, even though it has only just been downloaded from their servers. No email address to advise Apple of problem.

Hello, it's generally one of two thinks that cause this, but it is a bad download.
Try Ethernet instead of Airport if possible.
Disk can be corrupted...
Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
Try getting it direct instead of SWUPDate...
Repair Permissions afterwords, reboot.

When attempting to Sign a pdf document I am not finding the option to use an image, I'm only able to use a digital signature. I want to use a jpg file.

I click on Fill & Sign Tools, then I click Place Signature. The instructions show a dialog box with four options however that does not happen. I am only presented with the option of importing a digital signature. How do I get to the option of importing an image (jpg) signature?
Robert

I assume you have a digital ID set up already. When you sign then you need to select how the signature is to appear and you can then select create new appearance. Not sure if this is what you are dealing withage.

Since upgrading to version 11, I am unable to paste a signature image -- being forced to use a digital signature.

I would like to be able to place a signature image, as I did in previous versions. It seems as if I am being forced to use a digital signature, which the other side is not prepared to accept.

Hey there Jantje1,
It sounds like you are unable to launch iTunes and get an error message instead. I would try the troubleshooting outlined in this article named:
iTunes for Windows Vista, Windows 7, or Windows 8: Fix unexpected quits or launch issues
http://support.apple.com/kb/ts1717
If it comes down to uninstalling, then re installing iTunes altogether, use this link to download the 64 bit version of iTunes directly.

I created buttons and added a digital signature, when I saved and reopened my buttons disappeared?

I created a multi page PDF with numerous buttons for navigation. I realized I had forgotten to sign one of the individual pages, (I had recently added) so I simply put in a digital signature. I saved the document and reopened it later to find it made all the buttons non functional and uneditable... Some of the buttons were transparent (placed over written dates for reference) and some were colored boxes with text. The colored buttons became "flattened" and I could no longer edit them or click on anything.
Why did this happen? Is the digital signature to blame? Is there a way to edit the existing buttons or do I need to recreate all of them along with the actions associated with each? any assistance would be much appreciated!

It's possible to set up a signature field to lock other fields when it is signed. Could that be what happened? It also possible to choose to lock the file when signed to prevent changes. It's hard to tell what happened without seeing the file.

Get digital signature from TIFF image

Hi,
How can we get digital signature from the scanned TIFF image?
Thanks,

Do you mean a X.509 certificate or a digitalized image?
If its the first one, i don't think you can do it with Livecycle Alone.
If its the second one, anything from Paint to Corel will do.

How to increase the image size of a digital signature

No matter how large large I sign a piece of paper or how large a graphic file I use, or the format I save it as (PNG, PDF, JPG), when I go to actually place my signature in a signature box, the resulting image is tiny, as well as not terribly bold. One, how do I increase the size of how my scanned signature appears? And two, how do I make it appear more bold? Thank you for your help.

As it turns out, the way to make the image appear larger on the page is to edit and increase the size of the signature "box" on the pdf (under Forms > Add or Edit Fields), to considerably larger than the form might indicate. Otherwise, the signature is constrained to the just the size of the small field on the pdf. Interestingly, as soon as you do so, the signature appears "bolder", likely just because there is more of it. Thanks for your suggestions!

Digital Signature not allowed Acrobat 9.5.2

I created a form in Acrobat Pro and saved with extended functions. I'm using Acrobat Standard 9.5.2 which allows me to add digital signature. Most other employees can add signatures as well. However, there are a couple (using the same version software above) that when they open the file the security for digital signature is set to "Not Allowed". When I open the same document signatures are allowed. Therefore, is appears their software settings is setup differently than everyone elses. Can you help identify which setting needs to be changed?

Classification: For internal use only
I can't attach images at this point. The security method for both is No
Security. However, on the other user computer next to signature it states Not
Allowed. However, when they open the same form they see an error on top that
does not show up when I open the same form. The error message is, 'At least
one signature has problems. Please fill out the following form. You cannot
save data typed into this form. Please print your completed for if you would
like a copy for your records'. However, when I open the same for I do not get
that message. It almost seems like a security setting within their reader or
not.

Save as PDF, allow digital signatures in Reader

After saving the pdf from Pages, security permissions do not allow for digital signatures in Adobe Reader. How do I change this without having to use the full version of Adobe Acrobat?
...Bruce...

Hi Bruce,
Although you are creating the pdf from Pages, it's not Pages that is actually doing the conversion. Pages (and any other application for which pdf is not the 'native' file format) is using code that is part of the OS X package to convert the document to a pdf file.
If that code includes the capability of allowing digital signatures, Apple hasn't bothered to mention the fact in the Pages '09 User Guide. The only pdf option listed there for Export PDF is reduction of file size by resampling image files.
As the conversion is done with OS X bundled code, shared by all applications, you might find more useful answers in the Mac OS X v10.7 Lion community.

Barry

E-Pad and digital signatures

Folks,
Our company is implementing a new process wherein at the time of shipment, they would like to have the truck driver sign an e-Pad and the signature should be imported onto the bill-of-lading output. We have a customized delivery process and due to the volume of shipments, we do not want the truck drivers to spend anytime like saving the signature image to the desktop and then import into SAP etc.
We want the signature to be imported from the delivery screen (custom developed) onto the bill of lading output at the click of a button. We are using SAP version 4.7 and the e-Pad signature is from interlink electronics, who appear to be naive in SAP. We are open to look at other vendors for e-Pad or e-Signatures.
Hence, please help in the following ASAP:
1. Does SAP 4.7 have any limitations to import digital signatures?
2. Do anyone have any experience with e-Pad with interlink or can suggest any other vendor/product that can be readily used for this purpose?
Thanks and Regards,
Ram

Hi Reddy,
What I did was a image signature. Scan the signature into a image file, upload it to system via transaction code SE78.
Call the image to be printed on your form with the below code
BITMAP 'ZMY_SIGNATURE' OBJECT GRAPHICS ID BMAP TYPE BMON
Is this applicable to you?

Adobe XI when i use signature option i try to use rectangle, it gives option of certificate signature, does not give me webcam or digital signature or any other option to sign

when i use signature option i try to use rectangle, it gives option of certificate signature, does not give me webcam or digital signature or any other option to sign, have downgraded to Adobe X, no options show. Have upgraded back to XI no change. Free software I am using currently.

There are two types of signatures in PDF: electronic signatures, which are just images (stamps, text, image) and digital signatures.
If you want to use electronic signatures in Acrobat XI go to Fill&Sign->Place Signature. If a drag rectangle for the digital signature dialog comes up, you have selected digital signatures and Acrobat/Reader remembered it. Cancel it, go back to Fill&Sign->Place Signature and click a triangle to the left of "Place Signature". Then click on "Changed Saved Signature" and select the electronic signature type you want to use.
If you want to use digital signatures you can create custom digital signature appearance. Go to Edit->Preferences->Signatures->Creation&Appearance->More. In the "Appearances" section click "New". You will be presented with the dialog that allows you to create a custom appearance. If you want to put there your picture or image of your ink signature, you need to prepare this image as a file beforehand, select "Image" radio button, browse to the location of your image file. In Reader you can use only PDF as your image file. In Acrobat you can use many more file formats: JPEG, PNG, etc.
