Function Documentation

void CxImage::Clear (  BYTE  bval = 0  )  [inherited]

Sets the image bits to the specified value for indexed images, the output color is set by the palette entries. for RGB images, the output color is a shade of gray.

void CxImage::Copy (  const CxImage &  src, bool  copypixels = true, bool  copyselection = true, bool  copyalpha = true )  [inherited]

Copies the image from an exsisting source Parameters: src:  source image. copypixels:  copy the pixels from the source image into the new image. copyselection:  copy the selection from source copyalpha:  copy the alpha channel from source

void * CxImage::Create (  DWORD  dwWidth, DWORD  dwHeight, DWORD  wBpp, DWORD  imagetype = 0 )  [inherited]

Initializes or rebuilds the image. Parameters: dwWidth:  width dwHeight:  height wBpp:  bit per pixel, can be 1, 4, 8, 24 imagetype:  (optional) set the image format, see ENUM_CXIMAGE_FORMATS Returns: pointer to the internal pDib object; NULL if an error occurs.

bool CxImage::CreateFromArray (  BYTE *  pArray, DWORD  dwWidth, DWORD  dwHeight, DWORD  dwBitsperpixel, DWORD  dwBytesperline, bool  bFlipImage )  [inherited]

Creates an image from a generic buffer Parameters: pArray:  source memory buffer dwWidth:  image width dwHeight:  image height dwBitsperpixel:  can be 1,4,8,24,32 dwBytesperline:  line alignment, in bytes, for a single row stored in pArray bFlipImage:  tune this parameter if the image is upsidedown Returns: true if everything is ok

bool CxImage::CreateFromMatrix (  BYTE **  ppMatrix, DWORD  dwWidth, DWORD  dwHeight, DWORD  dwBitsperpixel, DWORD  dwBytesperline, bool  bFlipImage )  [inherited]

See also: CreateFromArray

bool CxImage::Destroy (   )  [inherited]

Call this function to destroy image pixels, alpha channel, selection and sub layers. Attributes are not erased, but IsValid returns false. Returns: true if everything is freed, false if the image is a Ghost

void CxImage::FreeMemory (  void *  memblock  )  [inherited]

simply calls "if (memblock) free(memblock);". Useful when calling Encode for a memory buffer, from a DLL compiled with different memory management options. CxImage::FreeMemory will use the same memory environment used by Encode.

bool CxImage::Transfer (  CxImage &  from  )  [inherited]

Transfers the image from an existing source image. The source becomes empty. Returns: true if everything is ok
