Write BITMAP data to file in C++

Hello all. I am currently trying to copy the header and pixel data from an image file and write this into a new image file. I am using a 256 colour bitmap and for testing have chosen a fixed height and width pixel of 150 and 90. A new file image file is created but when trying to load this, the following message is given: "Paint cannot read this file. This is not a valid bitmap file or its format is currently not supported. Would appreciate the support after many attempts. Below is the code I'm using:


02 const int height = 150;

03 const int width = 90;

04

05 unsigned char m_cHeaderData[1078];

06 unsigned char** m_cImageData = new unsigned char* [height];

07

08 for( int i = 0; i <height; i++)

09 {

10 m_cImageData[i] = new unsigned char [width];

11 }

12

13 ifstream* m_pInFile;

14 m_pInFile = new ifstream;

15 m_pInFile->open("image.bmp", ios::in | ios::binary);

16 m_pInFile->seekg(0, ios::beg);

17 m_pInFile->read(reinterpret_cast<char*>(m_cHeaderData), 1078); //bitmap bits start at offset 1078

18

19 for(int i = 0; i <height; i++)

20 {

21 m_pInFile->read(reinterpret_cast<char*>(m_cImageData[i]), width);

22 }

23

24 m_pInFile->close();

25

26 ofstream* m_pOutFile;

27 m_pOutFile = new ofstream;

28 m_pOutFile->open("imageCopy.bmp", ios::out | ios::trunc | ios::binary);

29 m_pOutFile->write(reinterpret_cast<char*>(m_cHeaderData), 1078);

30 for(int i = 0; i <height; i++)

31 {

32 m_pOutFile->write(reinterpret_cast<char*>(m_cImageData[i]), width;

33 }

34 m_pOutFile->close();

35

36

37 //deallocate memory:

38 delete m_pInFile;

39 delete m_pOutFile;

40 for(int i = 0; i <height; i++)

41 {

42 delete[] m_cImageData[i];

43 }

44 delete[] m_cImageData;

Please, format your code properly with indents and place it within the CODE tags!

Bitmap files have their own headers and data in special format . Pl read about that . You will get the file format on NET. The file starts with BM ...
