1156 % ReadPICTImage() reads an Apple Macintosh QuickDraw/PICT image file using
1157 % MacOS QuickDraw methods and returns it. It allocates the memory necessary
1158 % for the new Image structure and returns a pointer to the new image.
1160 % This method was written and contributed by spd@daphne.cps.unizar.es
1161 % (feel free to copy and use it as you want. No warranty).
1163 % The format of the ReadPICTImage method is:
1165 % Image *ReadPICTImage(const ImageInfo *image_info,
1166 % ExceptionInfo *exception)
1168 % A description of each parameter follows:
1170 % o image: Method ReadPICTImage returns a pointer to the image after
1171 % reading. A null image is returned if there is a memory shortage or
1172 % if the image cannot be read.
1174 % o image_info: the image info..
1176 % o exception: return any errors or warnings in this structure.
