| (NSImage *) | - getNSImage |
| Returns an NSImage for displaying. | |
| (void) | - getImageSample:withPrecision:withPlanes:atX:Y:W:H:lineWidth: |
| Retrieves image data for processing. | |
| (id< LynkeosImageBuffer >) | - getCustomImageSampleAtX:Y:W:H: |
| Retrieves image data in a custom format for calibration (see hasCustomImageBuffer). | |
It allows the application to access image data.

Retrieves image data for processing.
The (x,y) coordinate system has its origin in the top left corner of the image. The samples shall be ordered left to right, then top to bottom.
Most file formats share this orientation and pixels ordering.
Implementors can use the macro SET_SAMPLE to fill the output buffer.
| sample | An array of buffers to fill with image data | |
| precision | Wether the sample buffer shall be filled with floats or doubles | |
| nPlanes | The number of buffers in the array. It can be 1 (the data shall be converted to monochrome), or 3 (RGB data). | |
| x | X origin of the sample | |
| y | Y origin of the sample | |
| w | Width of sample | |
| h | Height of sample | |
| lineW | The number of samples in each line, as it can be larger than w there may be spare at the end of the lines. This only applies to sample |
