Pdf Merger not working above 300 MB

Hi,

I am using Dynamic PDF Merger to merge some PDF files. I have 3 PDF files with 138 MB, 170 MB and 217 MB. When i am trying to merge these 3 files dll is throwing "out of memory" exception. So how do we handle the pdf merger to merge the documents above 300 MB, becasue i observed the documents which are having above 300 MB are not merging by using PDF Merger.

Hello,

You are trying to merge a PDFs having bigger file size and the DynamicPDF Merger API builds the entire PDF in memory before the Draw method is called. Once the Draw method is called it starts generating the PDF and may need to assign more memory. By that time if there is not enough memory left to assign, it may throw an out of memory exception. You will need to make sure that you have sufficient resources available in your system to build and output the PDF document.

We are successfully able to generate a PDF of size 300MB without any problem. Our products are designed keeping the performance in mind and it will show a good performance. Please refer documentation on performance consideration here.

Hi Mod,

Thank you for the reply. As you said i did the same thing. Initially i am merging the files as

objMerge = ceTe.DynamicPDF.Merger.MergeDocument.Merge("File1.PDF","File2.PDF")

Then i appended the file as
objMerge.Append("FILE3.PDF")

Finally i used draw method to generate report but i am receiving the exception. As you said the draw method needs more in-memory to generate the PDF.

So will you please elaborate your below statement
"You will need to make sure that you have sufficient resources available in your system to build and output the PDF document. "

What do you mean by sufficient resources? do i need to increase in memory. if yes, how do i need to increase in memory? May u plz suggest the possible ways to increase the in-memory.

For my further details, i did a debug by using DebugDiag and the report is saying that the memory exception generated from

[hasThis] Void ceTe.DynamicPDF.IO.PageWriter..ctor(Class ceTe.DynamicPDF.Page,Class ceTe.DynamicPDF.IO.PageResources,Class ceTe.DynamicPDF.IO.DocumentWriter,I4,I4).

Let me know if any further details if you want.

Hello,

Our product is developed using fully managed code, so all memory management is left to the .NET. GC will handle all the memory management.

All the PDFs you are merging will be loaded into memory and will be written after merging to disk finally. This may take more memory as your input files are more than 500MB.

When you are working with very big files the application might not be getting enough memory allocated to work with big files and you are getting the out of memory exception.

What is the size of the RAM you are having and please give the system configuration. Also please give the details of the product version and build you are using. Please send these details to our support Team and they can look into it further.

Thanks,
