1.Modify the image, vector and label file path:
  In "util.h": Modify files path : INPUT_IMAGE_PATH, OUTPUT_IMAGE_PATH, INPUT_VECTOR_PATH, OUTPUT_VECTOR_PATH, INPUT_LABEL_PATH, OUTPUT_LABEL_PATH.
  						 Modify files name : INPUT_IMAGE_NAME, OUTPUT_IMAGE_NAME, INPUT_VECTOR_NAME, OUTPUT_VECTOR_NAME, INPUT_LABEL_NAME, OUTPUT_LABEL_NAME.
  
2.Modify the character indices which you want to get their images and vectors. Note: The minimun index is 1, not 0.
	In "util.h" : Modify character indices : CHAR_INDEX.
								Modify the number of character indices : INDEX_NUM.
	
3.The output of "readImage.cpp" and "drawImage.cpp".
	Each character in image file at "CHAR_INDEX" will come up in "OUTPUT_IMAGE_PATH + INPUT_VECTOR_NAME" in form of ".bmp".
	
4.The output of "readVector.cpp" and "drawVector.cpp".
	Each character in vector file at "CHAR_INDEX" will come up in "OUTPUT_VECTOR_PATH + OUTPUT_VECTOR_NAME" in form of ".bmp".
	
5.The output of "readLabel.cpp".
	The label file will come up in "OUTPUT_LABEL_PATH" + "OUTPUT_LABEL_NAME" in the form of ".txt".
