Function Documentation

int ReadPNG (  CMotion2DImage< short > &    I, const char *    filename )

Read the contents of the PNG filename, allocate memory for the corresponding gray level image, convert the data in gray level, and set the bitmap whith the gray level data. That means that the image I is a "black and white" rendering of the original image in filename, as in a black and white photograph. Returns: false if an error occurs, or true otherwise. If the image has been already initialized, memory allocation is done only if the new image size is different, else we re-use the same memory space. See also: ReadPGM(), ReadPPM(), WritePNG()

int WritePNG (  CMotion2DImage< short > &    I, const char *    filename )

Write the content of the bitmap in the file which name is given by filename. This function writes a PNG file. Warning: The resulted PNG image is a gray level image. Returns: false if an error occurs, or true otherwise. See also: ReadPNG(), WritePGM(), WritePPM()
