D1161: CopyFromMemory Requires CPU Readable Bitmap

  • Article

This method is not allowed on a bitmap created with D2D1_BITMAP_OPTIONS_CPU_READ.

 

Possible Causes

This message may occur during a call to ID2D1Bitmap::CopyFromMemory. If the bitmap was created using D2D1_BITMAP_OPTIONS_CPU_READ, Direct2D will report an error and the debug layer will output this message.

Possible Fixes

If it is necessary for an application to call ID2D1Bitmap::CopyFromMemory, ensure that the bitmap is not created as CPU-readable. If it is not possible to change the surface attributes of the bitmap, consider whether there is an equivalent rendering operation for the desired result.
