40c1649b0e fix is_solid return 2015-01-15 10:14:00 -06:00
Blake Thompson
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.

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

454326df17 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.

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?

4586586448 added convinence overloads for 'save_to_file' and 'render_to_file' 
Example:
	>>> from mapnik import *
	>>> im = Image(200,200)
	>> save_to_file('test.png',im) # Guess image type from file extension
	>> save_to_file('test.png,'jpeg',im) # Explicitly save as JPEG

f1393cc019 1. hit_test implementation for geometry objects: 
bool hit_test(double x, double y, double tol);
       
2. added image_view(unsigned x, unsigned y, unsigned width, unsigned height)
   allowing to select region from image data e.g (in Python):

    im = Image(2048,2048)
    view = im.view(0,0,256,256)
    save_to_file(filename,type, view)
    
3. changed envelope method to return vy value in datasource classes

4. features_at_point impl for shape and postgis plug-ins
