Le rendu de LocalReport échoue avec les images de Nikon Coolpix 5600

Question

J'ai un RDLC avec une image incorporée prise avec un Nikon Coolpix 5600 qui génère l'erreur suivante lorsque j'appelle la fonction Render.

exemple d'image: http://img140.imageshack.us/img140/4906/dscn1559u.jpg (lien mort)

quelqu'un sait-il ce qui ne va pas avec cette image?

L'erreur:

Answer 1

J'ai résolu le problème en recodant toute l'image avec System.Drawing.Bitmap Ce n’est pas une solution parfaite, mais cela fonctionne pour le moment.

Answer 2

L'image doit être encodée en Base64 pour pouvoir être rendue dans SSRS.

Voici une fonction VB.NET qui fera l’encodage. Vous pouvez probablement optimiser, je viens de coller une de mes anciennes fonctions.

Public Function ConvertImageToBase64String(ByVal img As Image) As String
    Dim output As String = ""
    Dim outputArray() As Byte
    Dim stream As New MemoryStream
    img.Save(stream, Drawing.Imaging.ImageFormat.Png)
    outputArray = stream.ToArray()
    stream.Close()
    output = Convert.ToBase64String(outputArray)
    Return output
  End Function
