I am creating a web application that generates PDF files using EO.PDF. When I execute it in my development environment works very fine but to upload it to a azure website it raises an 'Out of memory' error.
To isolate the error, I built a small application that tries to create and save a blank pdf document using a PdfDocument object and a pdfPage object. this is the code:
(Default.aspx)
<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="Default.aspx.vb" Inherits="PdfTest._Default" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:Label ID="Label1" runat="server" ></asp:Label>
</div>
</form>
</body>
</html>
(Default.aspx.vb)
Imports EO.Pdf
Imports EO.Pdf.Acm
Imports EO.Pdf.Contents
Imports EO.Pdf.Drawing
Public Class _Default
Inherits System.Web.UI.Page
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Try
'Create a new document
Dim doc As New PdfDocument()
'Add a new page
Dim page As PdfPage = doc.Pages.Add()
'Save the PDF file
Dim DocPath As String = System.IO.Path.GetTempPath & "tmp001.pdf"
doc.Save(DocPath)
Label1.Text = "OK"
Catch ex As Exception
Label1.Text = ex.Message & "<br><br>" & ex.StackTrace
End Try
End Sub
End Class
Again, it works OK in development environment, but to upload it to a test web site in azure (pdftest123.azurewebsites.net) the error is generated, so the error handler displays the following message in Label1
Out of memory.

at EO.Pdf.Contents.PdfContentContainer.k()
at EO.Pdf.PdfDocument.a()
at EO.Pdf.PdfDocument.Save(String fileName)
at PdfTest._Default.Page_Load(Object sender, EventArgs e)
As you can see, the error is occurring in the 'Save' command, but I am not able to interpret the specific cause much less solve the problem.
I ask for help, as the PDF generation is a critical issue for my project.
