4184f75011 Moved premultiply and demultiply out of image_32 and other parts of the code. The image_data object is now responsible for keeping track of its own premultiplied_alpha status. Created a new utility method in image_util to preform premultiplication.
Added visitor pattern to several different methods as well to prepare for image_data_any including compositing.

094d0ec3e1 Another large set of modifications, finally allow this branch to build. Mostly modifications to the image_util_* files. Different processing based on the image type is now possible, and save_to_stream now could possibly accept grayscale with out breaking existing code. 2015-01-08 19:31:14 -05:00

035557450d Split out the process for tiff, webp, and jpeg into their own util folders. Added the intial concepts for an image_view_any variant. 2015-01-08 16:55:51 -05:00

a3f6a989de An intial commit of a large set of changes attempting to clean up the way that saving images is processed in image_util.hpp and image_util.cpp.
* Changed the passing of rgba_palette to a shared_ptr in order to better facilitate the use of a visitor pattern.
 * Moved PNG util processing into its own set of files so that image_util_impl.hpp would not have to depend on HAVE_PNG.

0d2eb9cb5f Updates for Ref #2594 and #2592 (Related to #2491)
* Added support for scanline, stripped and tiled
 * Added new configuration options for TIFF:
   - method
   - tile_height (Default 0)
   - tile_width (Default 0)
   - rows_per_strip (Default 0)
 * Removed 'scanline' configuration option for TIFF.
 * Changed RGBA TIFFs to be ASSOCALPHA rather then UNASSOCALPHA

bf5c532269 Series of changes for the tiff encoder:
* Added configuration options for the TIFF encoder. The options are:
   - compression: adobe_deflate(default), deflate, lzw, none
   - zlevel: 0-9
   - scanline: 1,0 (Forces scanline encoding)
 * Fixed bug in encoder with scanline where memory was being modified
 * by TIFFWriteScanline. A buffer is now created for each row to prevent
 * modification of the underlying image_data.

38da080f82 make concrete image_data type names more expressive and explicit about color channels/depth:
image_data_32 -> image_data_rgba8
image_data_8  -> image_data_gray8
image_data_16 -> image_data_gray16
image_data_float32  -> image_data_gray32f

NOTE: currently image_data_gray16::pixel_type = std::int16_t (signed 16 bit int) to match GDAL
should we support unsigned types?
