I'm getting an error System.AccessViolationException to convert an object Drawing.Bitmap to Aurigma.GraphicsMill.Bitmap.

This is my code:
Code:

    Private Function ObterImagemAmpliadaParaPreviewDoTemplate() As Aurigma.GraphicsMill.Bitmap
        Dim imagemParaPreviewDoTemplate As Aurigma.GraphicsMill.Bitmap = Nothing
        Try
            imagemParaPreviewDoTemplate = Me.ObterImagemParaPreviewDoTemplate()

            Dim novoTamanhoDaImagem As Size = Me.CalcularTamanhoDaImagem.RetornaNovoTamanhoImagem(New Size(imagemParaPreviewDoTemplate.Width, imagemParaPreviewDoTemplate.Height), Me.FotoProdutoConfig.TamanhoMaxImagemAmpliadaTemplate)
            imagemParaPreviewDoTemplate.Transforms.Resize(novoTamanhoDaImagem, Aurigma.GraphicsMill.Transforms.ResizeMode.Fit, Aurigma.GraphicsMill.Transforms.InterpolationMode.HighQuality)
        Catch ex As Exception
            Throw New Exception("Falha ao obter imagem ampliada para preview do template.", ex)
        End Try
        Return imagemParaPreviewDoTemplate
    End Function



Stack Trace:
Code:

System.AccessViolationException : Tentativa de leitura ou gravação em memória protegida. Normalmente, isso é uma indicação de que outra memória está danificada.
   em memcpy(Void* , Void* , UInt32 )
   em Aurigma.GraphicsMill.Bitmap._Create(Bitmap bitmap)
   em Aurigma.GraphicsMill.Bitmap..ctor(Bitmap bitmap)
   em Aurigma.GraphicsMill.Bitmap.op_Implicit(Bitmap bitmap)
   em FotoProduto.ServidorTemplate.ImagensBmpDoPreviewDoTemplate.ObterImagemParaPreviewDoTemplate()


I think the error is in converting the object implicitly, in return of function.

Thank you for your help

Hi,

I tried to reproduce your problem locally but everything worked well.
Anyway, it is a very important problem, could you please submit the case and send us test application which allows to reproduce the problem. Also if this issue is reproduced on particular image, send me it too.

I get the error a few times.
But, I solved the problem.

code error:
Code:

    Private Function ObterImagemParaPreviewDoTemplate() As Aurigma.GraphicsMill.Bitmap
        Dim imagemParaPreviewDoTemplateBmp As System.Drawing.Bitmap = Me.VisualizadorMultiCamadas.RenderWorkspace.ToGdiplusBitmapDirectly()
        Dim imagemParaPreviewDoTemplate As Aurigma.GraphicsMill.Bitmap = imagemParaPreviewDoTemplateBmp
        Return imagemParaPreviewDoTemplate
    End Function


Code Correct:
Code:

    Private Function ObterImagemParaPreviewDoTemplate() As Aurigma.GraphicsMill.Bitmap
        Dim imagemParaPreviewDoTemplateBmp As System.Drawing.Bitmap = Me.VisualizadorMultiCamadas.RenderWorkspace.ToGdiplusBitmapDirectly()
        Dim imagemParaPreviewDoTemplate As New Aurigma.GraphicsMill.Bitmap(imagemParaPreviewDoTemplateBmp) //Instantiated
        Return imagemParaPreviewDoTemplate
    End Function


As I told the error sometimes occurs, and any jpg image.
Until now there was an error.
I really not understand why the error occured. I don't know difference between the lines modified, it is do the same thing.
