An image becoming all white and text corruption in some images

I have analyzed the issue more using ubuntu as follows:

  1. Got latest ubuntu docker image here and got the image using the following command:
    docker pull ubuntu

  2. Once the image is downloaded, executed it alongwith mounting my project folder
    docker run -it -v /Users/testuser/projects/:/projects ubuntu_dotnetcore:ver1 bash

  3. Following commands are executed in the container

  • apt update && apt upgrade

  • apt install wget

  • apt-get install sudo

  • wget https://packages.microsoft.com/config/ubuntu/20.04/packages-microsoft-prod.deb -O packages-microsoft-prod.deb

  • sudo dpkg -i packages-microsoft-prod.deb

  • sudo apt-get update; \
    sudo apt-get install -y apt-transport-https && \
    sudo apt-get update && \
    sudo apt-get install -y dotnet-sdk-3.1

  • sudo apt-get install libgdiplus

  • ln -s libgdiplus.so gdiplus.dll

  • sudo apt-get install libc6-dev

  1. When the installation was completed, then executed the program as follows:
  • dotnet run
    This command created the PDF fine and no image is white. Here is the output file attached for your reference:

I report back that I have been able to replicate the issue with docker + ubuntu.
Thank you very much. I attached the converted pdf file.

I have opened your PDF file and could not observe any issue as no white image is there. Could you please confirm if you have shared the right output file? Here is the comparison of your original PDF file and last PdF file result1_shun1985.pdf.

I’m sorry, this is due to my misleading expression “replicate the issue”.
I should have written “replicate the fix” as I meant to report that this fix have been well reflected.

So I have confirmed the two issues below are already resolved actually.
1. One image becomes all white (this is a Bitmap Image Object in the original Excel file) (page1)
2. Characters in an image are partly cutted off and seems mal-positioned (page1).
