    I have a report that needs png images of signatures on it. I have the raw image data stored in my database which looks like this,

    "‰PNGIHDR  ´     àÀÄÙ    IDATx^읛ÅÒ…Ž8À9øþÿ!:‚³
    gÃWï™>s[ciw$vWëê{ûckW35NW:õÅÑFÙÒi´@Z -H ¤Ò+j/Юè›ËÛN ¤Òi´@Z -Ðæ@H ¤Òi´@Z -Xi $ ]é×—7ŸH ¤Òi´@Z -€6Ç@Z -H ¤Òi´ÀJ[ íJ¿¾¼ù´@Z -H ¤Òi´9Òi´@Z -H "

    This data is accessible by my datasource. When I set the value of my picturebox to this field and change the mimetype to "image/png" I get an error that reads "Invalid image data"

    When I was using SSRS I would use PDF# and VB code to render this report into a pdf and the signatures into  system.drawing.image objects and then draw them onto the pdf with x and y coordinates.

    What I would really like to do is have this data render to an image in a Picturebox on my report so I no longer have to programatically place signatures onto a pdf of my report after is has been rendered as a pdf. I would like to see the signatures on my report in the reportviewer.

     

    Is this possible? thank you!

    -Kevin
