hello,

I've been working with this for quite a while, and cannot seem to get the background image to appear. I have read through the documentation, forum posts, and how-to's, but the image will not appear. I am working for a company that is looking into this product, and I am currently using the demo key. Here's the code:(vb .net)

sig.WidgetProps.AutoPos = False
sig.WidgetProps.AutoSize = True
sig.WidgetProps.AutoText = False
sig.WidgetProps.ShowTimestamp = False
sig.WidgetProps.SignerCaption = ""
sig.WidgetProps.AlgorithmCaption = ""
sig.WidgetProps.Header = ""
sig.WidgetProps.BackgroundStyle = SBPDF.TSBPDFWidgetBackgroundStyle.pbsCustom
sig.Invisible = False
sig.EmptyField = False
sig.WidgetProps.NoView = False
sig.WidgetProps.AutoStretchBackground = True
sig.WidgetProps.IgnoreExistingAppearance = False
Dim image As New SBPDF.TElPDFImage

'****putting the image in a byte array, then into the signature
Dim temp(imageFStream.Length) As Byte
imageFStream.Read(temp, 0, imageFStream.Length)
image.ImageType = SBPDF.TSBPDFImageType.pitJPEG2000
image.Data = temp
sig.WidgetProps.Background.Data = image.Data
sig.WidgetProps.Print = True
sig.WidgetProps.Background.ImageType = SBPDF.TSBPDFImageType.pitJPEG2000

Also, setting the image to pbsDefault also does not show an image; however, if I go into Adobe Reader and sign it manually with an image, the image appears just fine. The signature is being created from a field, but even when it isn't, the image will not appear. I can give more information if needed; any help will be appreciated.

Thank you.

1) Please post your image file.
2) You don't set dimensions of the widget. In case of custom background SecureBlackbox won't do this for you.


Sincerely yours

JFYI: There's a how-to article in the help file about setting a widget.

Also, please ensure that the image in JPEG 2000 format, not in JPEG 2000 code stream format or other.

Thank you for the help.
I did not realize that jpeg2000 code stream and jpeg2000 image file were two different file types; it seems that the freeware converter I found converts to the file stream type only. I dug up some jpeg2000 images with a web search, and upon setting the dimensions and using that file, the code worked. Now I just need a decent converter....

Again, thank you for your time.
