Function Documentation

bool ReadPGM (  CMotion2DImage< short > &    I, const char *    filename )

Read the contents of the portable gray pixmap (PGM P5) filename, allocate memory for the corresponding image, and set the bitmap whith the content of the file. 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: WritePGM(), ReadPPM(), ReadPNG()

bool ReadPGM (  CMotion2DImage< unsigned char > &    I, const char *    filename )

Read the contents of the portable gray pixmap (PGM P5) filename, allocate memory for the corresponding image, and set the bitmap whith the content of the file. 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: WritePGM(), ReadPPM(), ReadPNG()

bool ReadPPM (  CMotion2DImage< short > &    I, const char *    filename )

Read the contents of the portable pixmap (PPM P6) 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. The quantization formula used is . 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: WritePPM(), ReadPGM(), ReadPNG()

bool ReadPPM (  CMotion2DImage< unsigned char > &    I, const char *    filename )

Read the contents of the portable pixmap (PPM P6) 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. The quantization formula used is . 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: WritePPM(), ReadPGM(), ReadPNG()

bool WritePGM (  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 portable gray pixmap (PGM P5) file. Warning: Cast the content of the bitmap from short values to unsigned char values. Be aware, data can be lost. Returns: false if an error occurs, or true otherwise. See also: ReadPGM(), WritePPM(), WritePNG()

bool WritePGM (  CMotion2DImage< unsigned char >    I, const char *    filename )

Write the content of the bitmap in the file which name is given by filename. This function writes a portable gray pixmap (PGM P5) file. Returns: false if an error occurs, or true otherwise. See also: ReadPGM(), WritePPM(), WritePNG()

bool WritePPM (  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 portable pixmap (PPM P5) file. Warning: The resulted PPM P6 image is a gray level image. Returns: false if an error occurs, or true otherwise. See also: ReadPPM(), WritePGM(), WritePNG()

bool WritePPM (  CMotion2DImage< unsigned char >    I, const char *    filename )

Write the content of the bitmap in the file which name is given by filename. This function writes a portable pixmap (PPM P5) file. Warning: The resulted PPM P6 image is a gray level image. Returns: false if an error occurs, or true otherwise. See also: ReadPPM(), WritePGM(), WritePNG()
