Implement writing of CMYK and fix writing of image alpha channel (bug #32986). * __magick_read__.cc (bitdepth_from_class, init_encode_image): new functions created from pieces of encode_indexed_images () to be used by the other encode image functions. (encode_indexed_images): make use of new bitdepth_from_class(), and init_encode_image() functions. (encode_bool_image): rewritten to match flow of the other encode functions, use fortran_vec for performance, and use only 4th dimension for frames. (encode_uint_image): completely rewritten to identify images of CMYK type and not confuse them with RGB plus alpha channel. Now accepts the alpha channel as separate argument. Image argument must now be of same class as the template. (__magick_write__): changed to match new API for the encode functions. * private/__imwrite__.m: set default and input check for alpha channel option. * imwrite.m: document alpha channel option as separate argument. * NEWS: announce rewrite of the image IO functions and warn about possible backwards incompatibilities.

b59cc3252a51 NEWS update Jaroslav Hajek <highegg@gmail.com> parents: 9215 diff changeset	607 successfully used as indices, eliminating the conversion penalty for
10118 4de5c28733d5 edit NEWS file John W. Eaton <jwe@octave.org> parents: 10117 diff changeset	608 subsequent indexing by the same matrix. In particular, this means it
4de5c28733d5 edit NEWS file John W. Eaton <jwe@octave.org> parents: 10117 diff changeset	609 is no longer needed to avoid repeated indexing by logical arrays
4de5c28733d5 edit NEWS file John W. Eaton <jwe@octave.org> parents: 10117 diff changeset	610 using find for performance reasons.

10118 4de5c28733d5 edit NEWS file John W. Eaton <jwe@octave.org> parents: 10117 diff changeset	612 ** Logical matrices are now treated more efficiently when used as
4de5c28733d5 edit NEWS file John W. Eaton <jwe@octave.org> parents: 10117 diff changeset	613 indices. Octave will keep the index as a logical mask unless the
4de5c28733d5 edit NEWS file John W. Eaton <jwe@octave.org> parents: 10117 diff changeset	614 ratio of true elements is small enough, using a specialized
4de5c28733d5 edit NEWS file John W. Eaton <jwe@octave.org> parents: 10117 diff changeset	615 code. Previously, all logical matrices were always first converted
4de5c28733d5 edit NEWS file John W. Eaton <jwe@octave.org> parents: 10117 diff changeset	616 to index vectors. This results in savings in both memory and
4de5c28733d5 edit NEWS file John W. Eaton <jwe@octave.org> parents: 10117 diff changeset	617 computing time.

4de5c28733d5 edit NEWS file John W. Eaton <jwe@octave.org> parents: 10117 diff changeset	620 functions for better performance. These functions are now faster,
4de5c28733d5 edit NEWS file John W. Eaton <jwe@octave.org> parents: 10117 diff changeset	621 can deliver more economized results for ranges, and can reuse the

10118 4de5c28733d5 edit NEWS file John W. Eaton <jwe@octave.org> parents: 10117 diff changeset	640 ** The default behavior of `assert (observed, expected)' has been
4de5c28733d5 edit NEWS file John W. Eaton <jwe@octave.org> parents: 10117 diff changeset	641 relaxed to employ less strict checking that does not require the
4de5c28733d5 edit NEWS file John W. Eaton <jwe@octave.org> parents: 10117 diff changeset	642 internals of the values to match. This avoids previously valid

ae51dc447bab NEWS: update for release John W. Eaton <jwe@octave.org> parents: 8439 diff changeset	1280 Arithmetic with 64-bit integers (int64 and uint64 types) is fully
ae51dc447bab NEWS: update for release John W. Eaton <jwe@octave.org> parents: 8439 diff changeset	1281 supported, with saturation semantics like the other integer types.
ae51dc447bab NEWS: update for release John W. Eaton <jwe@octave.org> parents: 8439 diff changeset	1282 Performance of most integer arithmetic operations has been
ae51dc447bab NEWS: update for release John W. Eaton <jwe@octave.org> parents: 8439 diff changeset	1283 improved by using integer arithmetic directly. Previously, Octave
ae51dc447bab NEWS: update for release John W. Eaton <jwe@octave.org> parents: 8439 diff changeset	1284 performed integer math with saturation semantics by converting the
ae51dc447bab NEWS: update for release John W. Eaton <jwe@octave.org> parents: 8439 diff changeset	1285 operands to double precision, performing the operation, and then
ae51dc447bab NEWS: update for release John W. Eaton <jwe@octave.org> parents: 8439 diff changeset	1286 converting the result back to an integer value, truncating if
ae51dc447bab NEWS: update for release John W. Eaton <jwe@octave.org> parents: 8439 diff changeset	1287 necessary.
