How to get a void pointer to an Image's Pixels

advanced
#1

I need a void pointer to an image’s bitmap to pass to WINGDIAPI function WINAPI GetDIBits( )

In of_v0.9.3-vs_release I could code like this

ofImage image;
const void* pixelPtr;
pixelPtr = (const void*) image.getPixels();

It built and ran and my app worked fine.

Now when I try and build the same app in of_v0.9.8_vs_release I get this error
Error no suitable conversion function from “ofPixels_” to “void *” exists

I tried changing the pixelPtr type to unsigned char but I just get
Error no suitable conversion function from “ofPixels_” to “unsigned char *” exists

I think it may be something to do with the definition of ofPixels in 9.8, int has been changed to size_t everywhere.

I am doing a 32 bit build, but its no different for a 64 bit build.

Is there some way that I can get the pointer I need?

Thanks for any help

Maybe

image.getPixels().getData();

?

Thanks, I can compile this module now.
But I have issues elsewhere with the app so I can’t say for sure that it works yet.
