In npetraco/x3pr: Read/Write functionality for X3P surface metrology format

Description

A binary file. It is essentially a Windows Bitmap format file except that it contains two images. The first image is an RGB color image (i.e. a "texture") of the surface. The second image contains the z-height data in row-major order.

Format

A BITMAPFILEHEADER, the DIB header of the first image, image data for the first image (row major order), DIB header for the second image and image data for the second image (row major order). Info from the headers:
