High Dynamic Range

---

Detailed Description

Convenience routines to handle high dynamic range data. The application buffers are in float format.

Functions
pT_status	p_cce_read_float_xyz (const char *filename, pT_header *header, int frame, int field, float *r_or_x_frm, float *g_or_y_frm, float *b_or_z_frm, int width, int height, int stride)
pT_status	p_cce_write_float_xyz (const char *filename, pT_header *header, int frame, int field, float *r_or_x_frm, float *g_or_y_frm, float *b_or_z_frm, int width, int height, int stride)

Function Documentation

pT_status p_cce_read_float_xyz (  const char *  filename, pT_header *  header, int  frame, int  field, float *  r_or_x_frm, float *  g_or_y_frm, float *  b_or_z_frm, int  width, int  height, int  stride )

Convenience routines to read and write (XYZ) wide colour gamut and/or high dynamic range data. Parameters: filename  file to read/write header  pointer to pT_header struct frame  frame number field  0: frame, 1/2: field access. r_or_x_frm  address of R or X buffer in float format g_or_y_frm  address of G or Y buffer in float format b_or_z_frm  address of B or Z buffer in float format width  width of frame in memory. height  height of frame in memory. stride  stride of frame in memory. If the file is in integer format (e.g. P_16_BIT_FILE), float data range is assumed to be [0..1]. Otherwise, for P_16_REAL_FILE full float range is used.

pT_status p_cce_write_float_xyz (  const char *  filename, pT_header *  header, int  frame, int  field, float *  r_or_x_frm, float *  g_or_y_frm, float *  b_or_z_frm, int  width, int  height, int  stride )
