- * Although rotating and flipping data expressed as DCT coefficients is not
- * hard, there is an asymmetry in the JPEG format specification for images
- * whose dimensions aren't multiples of the iMCU size. The right and bottom
- * image edges are padded out to the next iMCU boundary with junk data; but
- * no padding is possible at the top and left edges. If we were to flip
- * the whole image including the pad data, then pad garbage would become
- * visible at the top and/or left, and real pixels would disappear into the
- * pad margins --- perhaps permanently, since encoders & decoders may not
- * bother to preserve DCT blocks that appear to be completely outside the
- * nominal image area. So, we have to exclude any partial iMCUs from the
- * basic transformation.
- *
- * Transpose is the only transformation that can handle partial iMCUs at the
- * right and bottom edges completely cleanly. flip_h can flip partial iMCUs
- * at the bottom, but leaves any partial iMCUs at the right edge untouched.
- * Similarly flip_v leaves any partial iMCUs at the bottom edge untouched.
- * The other transforms are defined as combinations of these basic transforms
- * and process edge blocks in a way that preserves the equivalence.
- *
- * The "trim" option causes untransformable partial iMCUs to be dropped;
- * this is not strictly lossless, but it usually gives the best-looking
- * result for odd-size images. Note that when this option is active,
- * the expected mathematical equivalences between the transforms may not hold.
- * (For example, -rot 270 -trim trims only the bottom edge, but -rot 90 -trim
- * followed by -rot 180 -trim trims both edges.)
- *
- * We also offer a lossless-crop option, which discards data outside a given
- * image region but losslessly preserves what is inside. Like the rotate and
- * flip transforms, lossless crop is restricted by the JPEG format: the upper
- * left corner of the selected region must fall on an iMCU boundary. If this
- * does not hold for the given crop parameters, we silently move the upper left
- * corner up and/or left to make it so, simultaneously increasing the region
- * dimensions to keep the lower right crop corner unchanged. (Thus, the
- * output image covers at least the requested region, but may cover more.)
- *
- * We also provide a lossless-resize option, which is kind of a lossless-crop
- * operation in the DCT coefficient block domain - it discards higher-order
- * coefficients and losslessly preserves lower-order coefficients of a
- * sub-block.
- *
- * Rotate/flip transform, resize, and crop can be requested together in a
- * single invocation. The crop is applied last --- that is, the crop region
- * is specified in terms of the destination image after transform/resize.
- *
- * We also offer a "force to grayscale" option, which simply discards the
- * chrominance channels of a YCbCr image. This is lossless in the sense that
- * the luminance channel is preserved exactly. It's not the same kind of
- * thing as the rotate/flip transformations, but it's convenient to handle it
- * as part of this package, mainly because the transformation routines have to
- * be aware of the option to know how many components to work on.

- * Henceforth the source version will match the shared-library major

- * PNG_LIBPNG_VER macro, which is not used within libpng but is available
- * for applications, is an unsigned integer of the form xyyzz corresponding
- * to the source version x.y.z (leading zeros in y and z). Beta versions
- * were given the previous public release number plus a letter, until
- * version 1.0.6j; from then on they were given the upcoming public
- * release number plus "betaNN" or "rcN".
- *
- * Binary incompatibility exists only when applications make direct access
- * to the info_ptr or png_ptr members through png.h, and the compiled
- * application is loaded with a different version of the library.
- *
- * DLLNUM will change each time there are forward or backward changes
- * in binary compatibility (e.g., when a new feature is added).
- *
- * See libpng.txt or libpng.3 for more information. The PNG specification
- * is available as a W3C Recommendation and as an ISO Specification,

- * Y2K compliance in libpng:
- * =========================
- *
- * June 26, 2010
- *
- * Since the PNG Development group is an ad-hoc body, we can't make
- * an official declaration.
- *
- * This is your unofficial assurance that libpng from version 0.71 and
- * upward through 1.4.3 are Y2K compliant. It is my belief that earlier
- * versions were also Y2K compliant.
- *
- * Libpng only has three year fields. One is a 2-byte unsigned integer
- * that will hold years up to 65535. The other two hold the date in text
- * format, and will hold years up to 9999.
- *
- * The integer is
- * "png_uint_16 year" in png_time_struct.
- *
- * The strings are
- * "png_charp time_buffer" in png_struct and
- * "near_time_buffer", which is a local character string in png.c.
- *
- * There are seven time-related functions:
- * png.c: png_convert_to_rfc_1123() in png.c
- * (formerly png_convert_to_rfc_1152() in error)
- * png_convert_from_struct_tm() in pngwrite.c, called in pngwrite.c
- * png_convert_from_time_t() in pngwrite.c
- * png_get_tIME() in pngget.c
- * png_handle_tIME() in pngrutil.c, called in pngread.c
- * png_set_tIME() in pngset.c
- * png_write_tIME() in pngwutil.c, called in pngwrite.c
- *
- * All handle dates properly in a Y2K environment. The
- * png_convert_from_time_t() function calls gmtime() to convert from system
- * clock time, which returns (year - 1900), which we properly convert to
- * the full 4-digit year. There is a possibility that applications using
- * libpng are not passing 4-digit years into the png_convert_to_rfc_1123()
- * function, or that they are incorrectly passing only a 2-digit year
- * instead of "year - 1900" into the png_convert_from_struct_tm() function,
- * but this is not under our control. The libpng documentation has always
- * stated that it works with 4-digit years, and the APIs have been
- * documented as such.
- *
- * The tIME chunk itself is also Y2K compliant. It uses a 2-byte unsigned
- * integer to hold the year, and can hold years as large as 65535.
- *
- * zlib, upon which libpng depends, is also Y2K compliant. It contains
- * no date-related code.
