2b8bd59d82 A large set of updates:
* Added new gray data types adding those to the variants and updating all the code necessary for them
* Added basic SSE to the image compare method, (only for RGBA) must be enabled with the -DSSE_MATH flag this is not yet put into the build process in any location.
* Fixed the resulting image for some TIFF visual tests, most likely they were incorrect due to fixes in TIFF reader
* Added some MAPNIK_DECL where necessary to grid rendering.
* Added support for more data types in GDAL plugin with grayscale images.
* Added views for all the new gray data types
* Updated python bindings for new gray data types.

89118c2fcb tiff_reader: only gaurd against over-allocation at read time 2015-01-26 16:33:30 -08:00

5d9f047002 Fixed some issues in color and bindings where you could create a color and premultiplied was not set and it was resulting in it being assigned randomly, causing some issues at runtime.
Updated some images in visual tests that were orginally set prior to all tiffs being premultiplied, this was causing a slight difference in a few pixels.

Updated the tiff tests a lot.

Fixed tiff reader so that it always considers everything read from RGB or RGBA as premultiplied. This is due to the fact that RGBA reader always premultiplies the alpha no matter its original form.

Put in a fix so that the file does not exist no longer shows up in the test running.

Fixed some failing tests in the c++ test due to tiffs now always being premultiplied for RGB(A)

a100b2fe1f Fixed the issues associated with TIFFs, now they always will return as premultiplied in the event they are rgba8 due to the way that the TIFF reader operates. Also added premultiply as a flag inside color class and exposed many of its components, made it so that setting and getting pixels took into consideration the state of the color and the image when dealing with the two. 2015-01-23 18:08:59 -06:00

51172c8fdf Move image_data.hpp to image.hpp and renamed most everything from image_data to image alone. This might lead to the need to clean up some variables that are currently named image through out the code at some time, but I think in the long term is much better as image is a better name for the base class. 2015-01-22 11:39:37 -06:00

0f388ed68f Changed the name of image_data_any to image_any. Moved header file for image_data_any to image_any. Ref #2633 2015-01-21 19:40:12 -06:00
Blake Thompson
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.

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

902858e55f tiff_reader: initial support for reading gray8/gray16/gray32f/rgba8/rgba16/rgba32f 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?
