ImageEditor crashes with large images

Hi,

I'm using the ImageEditor and it works fine for small pictures. But if I use for example an image with 5184x3888 pixels (180dpi, 5,6MB) my app crashes with the following exception:

"{System.ArgumentException: Offset and length were out of bounds for the array or count is greater than the number of elements from index to the end of the source collection.
   at System.IO.UnmanagedMemoryStream.Write(Byte[] buffer, Int32 offset, Int32 count)

StackTrace:

Do you have any ideas how to fix this problem?

Hi Frank, 

Greetings from Syncfusion. 

We have checked the reported problem with the image having 5760x3840 pixels (5.0MB) but we cannot reproduce the issue. So, could you please share the tested image and system configurations like OS version, RAM size, VS version, etc. This would help us to proceed further. 

Regards, 
Vignesh.

Hi Vignesh,

OS Version: Windows 10 Pro (1809) 64 Bit
RAM-Size: 8GB
Visual Studio Version: Professional 2017, 15.9.13

Regards,
Frank.

Hi Frank, 

Sorry for the delay. 

We have checked the issue in our source level. But we are not sure about it is due to our source level issue or framework level issue. Still we are checking the exact root cause of the issue and update you further details on 10th October 2019. We appreciate your patience until then. 

Regards, 
Vignesh.

Hi Frank,

 

Thanks for your patience. Further analysis with our source, we found that loading large size of image (5184 x 3888) caused insufficient memory exception and it is looks like there is some limitation in framework level. We have raised question in MSDN forum regarding this in the below link.

 

https://social.msdn.microsoft.com/Forums/en-US/98671f24-0a7a-4f5f-bc3c-d8b94a7b4b0f/insufficient-memory-to-continue-the-execution-of-the-program-while-calling

 

We will inform you further details once we get update from MSDN forum. Until that, we suggest you resize the image to (4584, 3438) or according to your machine configuration and save image.

 

Regards,

Bharathi.

Hi Frank, 
 
Sorry for the delay in response. We are unable to find the exact root cause of the issue whether it is framework level limitation or source level. So, we are still analyzing this issue with source and public forum. We will update you once we found the solution or root cause of the issue. Please change the image size and use as we suggest in our previous update until then.  
 
Thanks, 
Bharathi.

Hi Frank, 
 
We have checked the problem with source using the suggested solution from MSDN. But, while converting a bitmap image from array of bytes, it takes huge memory and throws out of memory exception. We are unable to handle this in our source since the issues occurs when using framework method to convert to a bit map. So, please use the previous suggested solution.

Bharathi.
