Any way to add graphic image from memory to map or layout

Anonymous User

Hi Guys,

I am currently developing an addin which will generate the image from memory dynamically (using system.Drawing c#)

And would like to check is there anyway to load the image into map or layout.

Those images shall represent soil sample information from particular point feature.

I found this method LayoutElementFactory.Instance.CreatePictureGraphicElement , but it can only be usable with file path.

So I have to save memory stream into file temporarily and load as element and delete the file.

Is there any way to load dynamically? Uma Harano‌
