char[] to bitmap

[Daan Schilder]

Hi, currently im working on an application to read data from a 4000 x 4000 CCD sensor. I can get the data from the CCD sensor into my computer, but only as an char array. This, i would like to convert to an bitmap. So what i did was, create a header for the bitmap, and tried to convert it to a memorystream. (bottom of following code). the error occurs in the line where I do this:


MemoryStream^ ms = gcnew MemoryStream(raw);

and says: No instance of constructor "System::IO::MemoryStream::MemoryStream" matches the argument list

argument types are: (unsigned char[48000054])

could anyone tell me how to convert my char [] to Bitmap the proper way?




void array2bmp(const char * img, int w, int h, PictureBox^ pb)

{




Bitmap^ b;

//FILE *f;

int filesize = 54 + (w + ((4 - (w % 4)) % 4)) * h * 3; //w is your image width, h is image height, both int

unsigned char bmpfileheader[14] = {B,M, 0,0,0,0, 0,0, 0,0, 54,0,0,0};

unsigned char bmpinfoheader[40] = {40,0,0,0, 0,0,0,0, 0,0,0,0, 1,0, 24,0};

unsigned char bmppad[3] = {0,0,0};

bmpfileheader[ 2] = (unsigned char)(filesize );

bmpfileheader[ 3] = (unsigned char)(filesize>> 8);

bmpfileheader[ 4] = (unsigned char)(filesize>>16);

bmpfileheader[ 5] = (unsigned char)(filesize>>24);

bmpinfoheader[ 4] = (unsigned char)( w );

bmpinfoheader[ 5] = (unsigned char)( w>> 8);

bmpinfoheader[ 6] = (unsigned char)( w>>16);

bmpinfoheader[ 7] = (unsigned char)( w>>24);

bmpinfoheader[ 8] = (unsigned char)( h );

bmpinfoheader[ 9] = (unsigned char)( h>> 8);

bmpinfoheader[10] = (unsigned char)( h>>16);

bmpinfoheader[11] = (unsigned char)( h>>24);

memcpy(raw, bmpfileheader, 14);

memcpy(raw+14, bmpinfoheader, 40);

unsigned char *dataptr = raw+54;

for(int i=h-1; i>=0; i--)

{

for(int j=0; j<w; j++)

{

if ((i & 1) == 0) //green - red line

{

if (j & 1) // red

{

*dataptr++ = *(img+i*w+j+w-1); //blue

*dataptr++ = *(img+i*w+j-1); //green

*dataptr++ = *(img+i*w+j); //red

}

else // green

{

*dataptr++ = *(img+i*w+j+w); //blue

*dataptr++ = *(img+i*w+j); //green

*dataptr++ = *(img+i*w+j+1); //red

}

}

else //blue - green line

{

if (j & 1) // green

{

*dataptr++ = *(img+i*w+j-1); //blue

*dataptr++ = *(img+i*w+j); //green

*dataptr++ = *(img+i*w+j-w); //red

}

else // blue

{

*dataptr++ = *(img+i*w+j); //blue

*dataptr++ = *(img+i*w+j+1); //green

*dataptr++ = *(img+i*w+j-w+1); //red

}

}

}

}

MemoryStream^ ms = gcnew MemoryStream(raw);

pb->Image = b->FromStream(ms);

}


Thanks in advance
