826e13f911 Renamed background to fill, added numeric casting to fill utility, changed clog uses to MAPNIK_LOG, changed the implementation of fill some so that it only used a single template 2015-01-29 13:27:42 -07:00

de99180a44 Added new image_cast method and added its bindings to python, added two new properities to images: offset and scaling. Added way to cast between image types with offset and scaling. Added new unit tests for color and casting. Made it so that pixel setting doesn't result in overflows or underflows. Made the return of get_pixel, dynamic based on what is passed to it. Added new methods for setting pixels that are doubles and ints. 2015-01-28 20:20:14 -06:00

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

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.

5bc83eee49 Added a new test for set_color_to_alpha 2015-01-15 21:03:42 -06:00

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.

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.

e6c5f705e5 Fixed error with selection criteria for stripe vs tiled, added modulus check on length and width to select striped in some situations, changed bitspersample for RBGA. (ref #2491) 2014-12-04 10:48:19 -05:00

cdaca0ba11 Updated tiff processing so now the encoder will utilize different types of data as well as will use Tile based encoding in most situations, if the image is large will revert to scanline based encoding. 2014-12-03 18:41:49 -05:00
