Is there a way I can send you the .Pdf form that is manifesting this behavior? I don't see a user file upload section in your forums.

Hi Ingo,

Sorry I did not include that line in my code snippet. It's actually in my original source code, a bit further up. So that is not the problem. I moved the line to just above where I set the field value, but it still has the same problem. The signature prints, but it is not visible in QuickPDF viewer, and it is not visible in an external .Pdf viewr like Adobe or Nuance Power PDF.

Any other suggestions? Thanks in advance.

Hi,

try it with an additional SetNeedAppearances(1) before SetFormFieldValue.

Cheers and welcome here,

Ingo

QuickPDF Library version: TDebenuPDFLibrary1013

Delphi XE3

I am using .Pdf fillable forms extensively in my production project. Each of the forms needs an image of a signature created and inserted at runtime, in place of a fillable text field that is being used simply as a place holder.

I am using the following code to grab the dimensions of the fillable text field, then I basically "get rid of it" then I display the signature .Jpg image. This works. However, after the form is saved, then reopened, the signature field is not being displayed in QuickPDF, nor in an external .Pdf viewer like Adobe. However, upon printing, the signature shows up on the hard copy, in the correct place and it's the correct size.

I need to know how to force QuickPDF or Adobe, to display the signature image .jpg that I know is there (because it prints), but is not being shown.

Only 1 form out of 331 forms has this problem. All other forms display the signature image in QuickPDF and Adobe even after having been saved and reloaded.

----------------------------------------------------------------------

// Set text to blank, Grab the dimensions, then get rid of the "place holder" text field

ff_val := '';

idx := 29;

qwk_pdf.SetFormFieldValue(idx, ff_val);

sig_lft := qwk_pdf.GetFormFieldBound(idx, 0);

sig_top := qwk_pdf.GetFormFieldBound(idx, 1);

sig_wdt := qwk_pdf.GetFormFieldBound(idx, 2);

sig_hgt := qwk_pdf.GetFormFieldBound(idx, 3);

qwk_pdf.SetFormFieldVisible(idx, 0);

qwk_pdf.UpdateAppearanceStream(idx);

// Draw the image of the signature

sig_blb_strm := dmCln.cdsPrvdr.CreateBlobStream(dmCln.cdsPrvdrSIG_JPG, bmRead);

img_id := qwk_pdf.AddImageFromStream(sig_blb_strm, 0);

qwk_pdf.DrawImage(sig_lft, sig_top, sig_wdt, 20);

...

qwk_pdf_frm.SaveToFile(ff_mrg_fyl_nm);

...

// At this point the signature image displays correctly in QuickPDF and Adobe. However, when I reload the image into QuickPDF, or reload into Adobe, the signature image is not visible. However, it prints onto the hard copy.
