[ome-devel] [ome-files] Copying ROI from C++ Array to VariantPixelBuffer

[Dennis Ai]

Hi OME Team,

 

As part of the image acquisition pipeline we are developing, I would like to
be able to selectively copy a 3D-ROI into a VariantPixelBuffer so it can be
written to an OME-TIFF.  In the documentation
<https://docs.openmicroscopy.org/ome-files-cpp/0.5.0/ome-files/api/html/clas
some_1_1files_1_1VariantPixelBuffer.html#a78436203a3b2fabbcf6c20d8753329df>
for VariantPixelBuffer, it says that adding support for subsetting
dimensions is a to-do.

 

The function prototype would look something like this.  It would allow us to
copy a buffer into a ROI of the pixel buffer as defined by an x-offset,
y-offset, z-offset, and width (x), height (y), and depth (z).

 

void CopyROI(float* buffer, int x, int y, int z, int width, int height, int
depth)

 

I am happy to write my own extension method, but was wondering what would be
the best way to implement this.  Would it be to use boost::static_visitor?

 

Thanks,
