However for this one - we have 2 elements rotating, giving the impression of a orbit. Show demo Browser Support The numbers in the table specify the first browser version that fully supports the property. This property allows you to rotate, scale, move, skew, etc., elements. We use the same keyframe animation as above - eg rotate (360deg). Definition and Usage The transform property applies a 2D or 3D transformation to an element. The below example shows another loading animation that we can do with CSS rotates. So there should be none changed in this test. Example 2: Loading animations with CSS orbit rotation. All pixels not within threshold are changed to set_color. See the threshold tests for a full of examples: ĭef test_threshold_dest_surf_not_change ( self ): """ the pixels within the threshold. The number of pixels that are within the 'threshold' in 'surf'Ĭompared to either 'search_color' or search_surf. True, Pixels within threshold are changed. Look at the color in 'search_surf' rather than using 'search_color'.įalse, default. Search_surf ( pygame.Surface pygame object for representing images or None). Set_behavior=2 pixels set in 'dest_surf' will be from 'surf'. Set_behavior=0 we do not change 'dest_surf', just count. Pixels in dest_surface will be changed to 'set_color'. Set_color ( pygame.Color pygame object for color representations or None) - Color we set in dest_surf. So you could use an r threshold of 40 and a blue threshold of 2 You can use a threshold of (r,g,b,a) where the r,g,b can have different Threshold ( pygame.Color pygame object for color representations) - Within this distance from search_color (or search_surf).
Search_color ( pygame.Color pygame object for color representations) - Color we are searching for. Surf ( pygame.Surface pygame object for representing images) - Surface we are looking at. Should be None if counting (set_behavior is 0). 'surf' that is within the 'threshold' of the pixel at the same coordinatesĭest_surf ( pygame.Surface pygame object for representing images or None) - Surface we are changing. If the optional 'search_surf' surface is given, it is used to threshold against The pixels that ARE within the threshold are changed to set_color. If inverse_set is optionally set to True, It can also be used to transfer pixels into a 'dest_surf' that match or don't match.īy default it sets pixels in the 'dest_surf' where all of the pixels NOT within the Or close to colors in a separate 'search_surf'.
This are used to rotate the text in either clock wise or anti. This versatile function can be used for find colors in a 'surf' close to a 'search_color' Rotate text can be done by using rotate() function in CSS. Threshold(dest_surface, surface, search_color, threshold=(0,0,0,0), set_color=(0,0,0,0), set_behavior=1, search_surf=None, inverse_set=False) -> num_threshold_pixels
