Aspose TIFF to PDF returns blank PDF in Windows Dev Server using java springboot

[akrishnamurthy]

I’m using Aspose evaluation version to test aspose tiff to pdf conversion in a java springboot app deployed in my local JBOSS server. I could test my changes in local where the pdf generates as expected along with the water mark of evaluation.
However when I try to run the same application in JBOSS within a Windows server(DEV) I see that we are getting a blank PDF with only the watermark “Evaluation Only. Created with Aspose.PDF. Copyright 2002-2023 Aspose Pty Ltd.” The application logs are clean and no exceptions are logged. only the data is not getting populated… Please advise.

We are looking into it and will be sharing our feedback with you shortly.

Can you please make sure that you are using a valid or 30-days free temporary license while using the API. Also, please ensure that all Windows fonts are installed and present on the server where application is deployed. Please share your sample source and output files with us in case issue still persists. WE will test the scenario in our environment and address it accordingly.

Thanks for the response. Can we use an evaluation version in windows server ? or do we need a temp or permanent license to run in a server? cos in my case I used the jar file which I downloaded from (Aspose Repository Browser /java/repo/com/aspose/aspose-pdf/). This jar generated the PDF with data in my local machine along with the watermark "Evaluation Only. Created with Aspose.PDF. Copyright 2002-2020 Aspose Pty Ltd” at the top. however, running the same app in a windows server responded with a blank PDF with only the watermark "Evaluation Only. Created with Aspose.PDF. Copyright 2002-2020 Aspose Pty Ltd” at the top.

I will validate the application using the temporary license and check how it works.

I have couple of questions with license,

1. We have a need to perform Tiff to PDF and PDF to Tiff conversion. will Aspose.PDF license be sufficient to handle this request or will we need the Aspose Total? Please confirm.
2. Whats the key difference between Developer OEM and Site OEM license … The use case we have here is to use in one applicaiton for 2 use cases. we will be deploying this applicaiton in Dev, SIT, UAT and PROD - will a Developer OEM license be suffice?

You can use trial version (without license) for as long as you want with certain limitations:

• It will not process more than 4 elements of any collection e.g. Pages, Paragraphs, TextFragments, etc.
• An evaluation message will be printed at the top of PDF page in the output

Therefore, using it with a temporary license will clear the doubt if there is an issue with the API or it is happening due to trial version limitations.

Only Aspose.PDF license would be sufficient for this feature because API provides both PDF to TIFF and TIFF to PDF conversions. Unless you want to further process image data, you will need Aspose.Imaging as well.

We recommend that you please create a post in our purchase forum where you will be assisted against your above concerns.

I updated the application with Aspose temporary license, However the issue remains. we still see that the application is working as expected by converting the tiff files to PDF . However the same artifact deployed in a Development server is generating a blank pdf with no errors/exceptions in logs. There is no clue on why this is happening. Any help to get this resolved would be greatly appreciated.

Can you please share the sample code snippet that you are using with the input and output files generated on the server? We will log an investigation ticket and share the ID with you.

[akrishnamurthy]

I have shared the code snippet and output files here however I will not be able to share the input file as it has PII data… Need immediate assistance.

I saw another thread in aspose forum where a similar issue was discussed for aspose.pdf for .NET. Sharing that here for reference,

ASPOSE.PDF - Converting TIFF To PDF Gives Blank PDF

@asad.ali Any update on the ticket PDFNET-48803? As well on the issue posted by @mcorven We are waiting on a quick resolution for this; as we are kind of blocked due to this which will essentially impact the delivery. Please let know early by when we can expect a fix (OR) at least a workaround for this issue? It’s been already 7 days the ticket has been logged at your end. Thank You.
