Apache PDF Box can convert PDFs to jpg,bmp,wbmp,png, and gif. ... 2) Java: Generating PDF and Previewing it as an Image – iText and PDF ... I struggled quite a bit to find out why the OpenForecast assembly, which we discussed in chapter 6, was failing to execute regardless of the fact that it was given FullTrust permission rights. I went through all possible permutations but to no avail. The strange thing was that neither OpenForecast nor its caller was accessing external resources. I went to the trouble of converting it to C# only to realize that the C# version was executing properly. Finally, I resorted to using System.Diagnostics.Trace.WriteLine to find out at what point the code was failing. Using the DbgView utility I was able to pinpoint the security violation to an overridden implementation of the toString method inside the OpenSource DataSet structure. My code was calling this method to output the observed and forecasted values. Removing the tracing calls fixed the problem. The exact reason for the security violation was beyond me, but the moral of my story is this. If giving your custom code FullTrust permissions doesn t help, you should start exploring your code to find out at what point it fails. Once you manage to identify the offending line, the next step will be to find out which code access security permissions it requires. As a last resort, if nothing else works, you could bypass the Report Server CAS policy by commenting out the securityPolicy element in web.config, as I noted before. Before you decide to do this, however, make sure that you have a convincing story when you are asked to stand before the CAS court. java convert pdf to image: How to convert an image to a PDF in Java - Java PDF Blog java pdf to image open source Apache PDFBox Convert PDF to Image in Java - Memorynotfound

I have been trying to add an image to all pages using iTextSharp . ... If you want an iText for C# example, you'll discover that it is very easy to port the Java to C#. Currently, to the best of my knowledge, there is no tool to help you troubleshoot code access security problems. What I would like to see in future versions of the .NET Framework is more explanatory error descriptions when a security exception is thrown. At least the exception message should spell out name of the failing permission and the offending line of code. My experience is that often this information is missing. Granting custom assemblies FullTrust rights Back in chapter 6 we said that AWC.RS.Library and OpenForecast assemblies require full trust permissions to execute successfully. Let s see what changes are required to accomplish this. The assemblies don t require any custom permission sets. To elevate the code access security policy for both assemblies from Execution to FullTrust, we need to add the following lines to the Report Designer (rspreviewpolicy.config) and Report Server (rssrvpolicy.config) security configuration files: 288 java convert pdf to image How to convert an image to a PDF in Java - Java PDF Blog

This is why we specifically granted full rights to both the AWC.RS.Library and OpenForecast assemblies. Dealing with unmanaged resources Sometimes, granting your custom code the FullTrust permission set may not be enough. This may be the case when you need to deal with unmanaged resources. For example, you could have authored a custom dataset extension that opens a database connection through the .NET System.Data.SqlClient.SqlConnection managed wrapper to a SQL Server database. A database connection is an unmanaged resource, and your custom code requires explicit permissions to execute unmanaged code. Specifically, you need to declare a new permission set, as shown here: TRY IT NOW Type Help Get-Ev and press Tab. My first match is Get-Event, Each of the values in the left column of the table below refers to a number of computers that a given network must support. In the corresponding space in the right column, specify with a subnet mask in slash notation the smallest network address size that will accommodate those computers. The first row is provided as an example. (Hint: remember to add two to the number of hosts in order to determine the number of addresses needed.) <PermissionSet class="NamedPermissionSet" version="1" Unrestricted="true" Name="MyPermission"> <IPermission class="SecurityPermission" version="1" Flags="UnmanagedCode" /> </PermissionSet> Number of Network Hosts 18 125 400 127 650 7 2000 4 3500 20 32 Subnet Mask (/n) /27 Answer: Then you need assert the permission needed in your custom code before accessing the unmanaged resource: Number of Network Hosts 125 400 127 650 7 2000 4 3500 20 32 Subnet Mask (/n) /25 /23 /24 /22 /28 /21 /29 /20 /27 /26 SqlClientPermission permission = new SqlClientPermission(PermissionState.Unrestricted); try { permission.Assert(); // Assert security permission! java convert pdf to image How to Convert PDF to JPEG/JPG in Java - pqScan.com
