% ConstituteImage() returns an image from the pixel data you supply.
|
|
|
% The pixel data must be in scanline order top-to-bottom. The data can be
|
|
|
% char, short int, int, float, or double. Float and double require the
|
|
|
% pixels to be normalized [0..1], otherwise [0..QuantumRange]. For example, to
|
|
|
% create a 640x480 image from unsigned red-green-blue character data, use:
|
|
|
%
|
|
|
% image = ConstituteImage(640,480,"RGB",CharPixel,pixels,&exception);
|
|
|
%
|
|
|
% The format of the ConstituteImage method is:
|
|
|
%
|
|
|
% Image *ConstituteImage(const size_t columns,const size_t rows,
|
|
|
% const char *map,const StorageType storage,const void *pixels,
|
|
|
% ExceptionInfo *exception)
|
|
|
%
|
|
|
% A description of each parameter follows:
|
|
|
%
|
|
|
% o columns: width in pixels of the image.
|
|
|
%
|
|
|
% o rows: height in pixels of the image.
|
|
|
%
|
|
|
% o map: This string reflects the expected ordering of the pixel array.
|
|
|
% It can be any combination or order of R = red, G = green, B = blue,
|
|
|
% A = alpha (0 is transparent), O = opacity (0 is opaque), C = cyan,
|
|
|
% Y = yellow, M = magenta, K = black, I = intensity (for grayscale),
|
|
|
% P = pad.
|
|
|
%
|
|
|
% o storage: Define the data type of the pixels. Float and double types are
|
|
|
% expected to be normalized [0..1] otherwise [0..QuantumRange]. Choose
|
|
|
% from these types: CharPixel, DoublePixel, FloatPixel, IntegerPixel,
|
|
|
% LongPixel, QuantumPixel, or ShortPixel.
|
|
|
%
|
|
|
% o pixels: This array of values contain the pixel components as defined by
|
|
|
% map and type. You must preallocate this array where the expected
|
|
|
% length varies depending on the values of width, height, map, and type.
|
|
|
%
|
|
|
% o exception: return any errors or warnings in this structure.

% WriteImages() writes an image sequence into one or more files. While
|
|
|
% WriteImage() can write an image sequence, it is limited to writing
|
|
|
% the sequence into a single file using a format which supports multiple
|
|
|
% frames. WriteImages(), however, does not have this limitation, instead it
|
|
|
% generates multiple output files if necessary (or when requested). When
|
|
|
% ImageInfo's adjoin flag is set to MagickFalse, the file name is expected
|
|
|
% to include a printf-style formatting string for the frame number (e.g.
|
|
|
% "image%02d.png").
|
|
|
%
|
|
|
% The format of the WriteImages method is:
|
|
|
%
|
|
|
% MagickBooleanType WriteImages(const ImageInfo *image_info,Image *images,
|
|
|
% const char *filename,ExceptionInfo *exception)
|
|
|
%
|
|
|
% A description of each parameter follows:
|
|
|
%
|
|
|
% o image_info: the image info.
|
|
|
%
|
|
|
% o images: the image list.
|
|
|
%
|
|
|
% o filename: the image filename.
|
|
|
%
|
|
|
% o exception: return any errors or warnings in this structure.
