Hello, everyone.
I just dont know how to convert the format of the result directly to CImage. I used to export the result as an image file, then loaded them by CImage class. Althoug i know the class DrawArea can directly export the image into memory, but i just don't know how to convert the MemBlock to Cimage. Who can give me an example?
Thank you!

Hi Yonggang,
ChartDirector can output the image to memory, which you already know.
To create a CImage with image from memory, you would need to refer to Microsoft documentation or Microsoft support forums.
You may try using CImage::Load(IStream*) to load an image from an IStream, in which the IStream can be created using CreateStreamOnHGlobal using global memory which is a copy of the the image memory.
