125 <p>GetAuthenticPixels() obtains a pixel region for read/write access. If the region is successfully accessed, a pointer to a Quantum array representing the region is returned, otherwise NULL is returned.</p>
129 <p>Pixels accessed via the returned pointer represent a simple array of type Quantum. If the image has corresponding metacontent,call GetAuthenticMetacontent() after invoking GetAuthenticPixels() to obtain the meta-content corresponding to the region. Once the Quantum array has been updated, the changes must be saved back to the underlying image using SyncAuthenticPixels() or they may be lost.</p>
131 <p>The format of the GetAuthenticPixels() method is:</p>
134 Quantum *GetAuthenticPixels(Image *image,const ssize_t x,
317 <p>Pixels accessed via the returned pointer represent a simple array of type Quantum. If the image type is CMYK or the storage class is PseudoClass, call GetAuthenticMetacontent() after invoking GetAuthenticPixels() to access the meta-content (of type void) corresponding to the the region.</p>
319 <p>If you plan to modify the pixels, use GetAuthenticPixels() instead.</p>
321 <p>Note, the GetVirtualPixels() and GetAuthenticPixels() methods are not thread- safe. In a threaded environment, use GetCacheViewVirtualPixels() or GetCacheViewAuthenticPixels() instead.</p>
359 <p>Pixels accessed via the returned pointer represent a simple array of type Quantum. If the image type is CMYK or the storage class is PseudoClass, call GetAuthenticMetacontent() after invoking GetAuthenticPixels() to obtain the meta-content (of type void) corresponding to the region. Once the Quantum (and/or Quantum) array has been updated, the changes must be saved back to the underlying image using SyncAuthenticPixels() or they may be lost.</p>
