Hi,
I load an image(768*256) using a file path(OpenImageFilePath).
After load an image, I start to read the loaded Image data using GetBits method and plot the same image data(768*256).
I'm using the memcpy method, for that i'm getting the below error. memmove function also giving the same error message.
Please clear me.
File Name : memcopy.asm
rep movsd ;N - move all of our dwords
Code for your reference
