• Multiply the matrix by scalar
• Operator (rowIndex, colIndex) - get the value in the matrix.
• rotate90Degrees - return a matrix after rotating this matrix.

• Exception that is dealing with the ErrorCode errors in the Matrix section.

• Exception that is dealing with message errors in the BMP section.

• rotating the BMP picture 90 degrees clockwise.
• converting the BMP picture to gray scale one.
• writeToFile - write the photo into a BMP file.
• setters to all the members in the class.
• getters to some of the members.
• toGray (private) - returns a color from a 3 given numbers. (rgb)

• bytesToUnsignedInt - convert 4 bytes to unsigned int.
• bytesToSignedInt - convert 4 bytes to signed int.
• parseHeader - parsing Header of the picture. (with this private methods)
  • parseMagic - parse the magic.
  • parseBmpFileSize - parse the size of the BMP file.
  • parseReserved - parse the reserved.
  • parsePixelArrayAddress - parse the offset of the pixel array in bytes.
• parseDIBHeader - parsing DIBHeader of the picture. (with this private methods)
  • parseHeaderSize - parse the size of the DIBheader. (must be 40)
  • parseBitmapWidth - parse the width of the bitmap.
  • parseBitmapHeight - parse the height of the bitmap.
  • parseConstant - parse the constant. (must be 1)
  • parseBitsPerPixel - parse the bits per pizel (8 or 24)
  • parseCompression - parse the compression (must be 0)
  • parseBitmapSizeWithoutCompression - parse the bit map size without compression. (might be 0)
  • parseResolution - parse the revolution. (width and height)
  • parseNumOfColors - parse the number of colors.
  • parseNumOfImportantColors - parse the number of important colors.
• parseColorPallete - parse the color pallete. (only for 8 bits per pixel)
• parseBitmapArray - parse the bitmap array. (only for 24 bits per pixel)
• getPicture - get the picture that was parsed.

• Has three members (chars): m_red, m_green, m_blue.
• Has a constructor.
• Has getters to the members.
• Has a ToGray function - return a new color that is a grayscale of this color.
• Has an isEqual function - checks if this color and the given color are the same.

• isBMPFile - checks if the input file is a bmp file.
• isValidFile - checks if the file exists.

• rotate_image - we checked if output and input files are bmp files and if the input file exists and then we rotated the image.
• convert_to_grayscale - we checked if output and input files are bmp files and if the input file exists and then we converted the image to grayscale.

• Tested the Matrix part with tests that we made.
• Tested the code with tests that we got from our fellow students.
• Tested the BMP with the "woman" that you gave us.
• Tested the BMP with a couple more photos that we created.

Note: If you want us to give you good songs every excercise ler us know!!!
