bc28c12572 Found more situations where getRowSize should be used over multiplying the width by the pixel size. 2015-01-27 15:29:43 -06:00

b090882902 Added compare utility to python bindings and image_util, modified set_grayscale_to_alpha to take a color optionally. 2015-01-27 11:41:05 -06:00
Blake Thompson
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

aa03cf4f7c Implemented a new get_pixel method to go along with the set_pixel method in image_util. Ref #2633 2015-01-16 22:15:33 -06:00

a002139e18 Added set_pixel to visitor pattern and moved it to image_util. Added exception throwing in composite only if debug flags are on.

aebb6fee58 Removed the background and set/get background from image_32 class. Removed clear method from image_32. Added new fill method for image_data_any, that allows many generic types to fill an image.

3b1c99ff1b Moved set_alpha to src/image_util.cpp and out of image_32. Added a boolean response to premultiply_alpha and demultiply_alpha so that if it is changed in set_alpha and other locations like the python bindings for composite that the image can be restored to its original state. Removed blend from python bindings.

cf646030f3 move is_solid to hpp for now to avoid linking errors 2015-01-15 10:21:11 -06:00

7ce7416999 Added is_solid to image_utils. It is currently built to support the eventual use of image_view_any and image_data_any, but for a limited time supports the passing of image_view_rgba8 and image_data_rgba8.

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

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?
