Version 1.0.10 is out
Fastest and improved version of PygameShader, 15-20% faster CPU algorithms
New CPU demonstrations available:
- demo_burst
- demo_burst_exp (experimental)
- demo_fire_border
- demo_predator
- demo_magnifier
- demo_rain
- demo_ripple
- demo_transition_inplace
- demo_tunnel
- demo_wave_static
Added following Cython flags to all libraries and methods
@cython.profile(False)
@cython.initializedcheck(False)
Fast math operations by using C float precision e.g cosf, sinf, atanf etc.
This changes apply only for windows version AMD64 and Win32 (all libraries using libc.math)
Linux versions is still using double precision
Added Fast RGB to HSL color conversion model for a given color
cpdef inline hsl _rgb_to_hsl(unsigned char r, unsigned char g, unsigned char b)nogil
cpdef inline rgb _hsl_to_rgb(float h, float s, float l)nogil
Added fast RGB to HSV color conversion model for a given color
cpdef inline hsv _rgb_to_hsv(unsigned char r, unsigned char g, unsigned char b)nogil
cpdef inline rgb _hsv_to_rgb(float h, float s, float v)nogil
What's changed
Renamed various Cython methods (cdef & cpdef methods) to simplify
Improved and simplified many CPU algorithms.
Version 1.0.10 is 10-20% faster than 1.0.9
New BlendFlags library.
This library is similar to Pygame special flags attribute.
Unlike Pygame, where only surface can be blend together, this library allow you
to blend directly 3d arrays(w, h, 3) and 2d arrays shape (w, h) together (texture vs texture or
alpha channels vs alpha).
Blending array together is much faster than converting both surfaces into equivalent
arrays or converting arrays into Surfaces to blend pixels together.
Removing unnecessary steps improved the performances and can make your game or code running
much faster when you need to apply transformation to the array level and not textures.
Added blit_s function (blend a sprite to an image or surface)
Added blend_add_surface (blend surfaces, equivalent to BLEND_RGB_ADD)
Added blend_add_array (blend two 3d arrays together, equivalent to BLEND_RGB_ADD for arrays)
Added blend_add_alpha (blend two 2d arrays together, equivalent to BLEND_RGB_ADD for alpha channels)
Added blend_sub_surface (blend surfaces, equivalent to BLEND_RGB_SUB)
Added blend_sub_array (same for arrays)
Added blend_min_surface (blend surfaces, equ to BLEND_ADD_MIN)
Added blend_min_array (same for arrays)
Added blend_max_surface (blend surface with BLEND_RGB_MAX flag)
Added blend_max_array (same for arrays)
New BurstSurface library
This library provides new tools to transform PNG & JPG images into multiple sub-surfaces or pixels block.
It contains tools to produce images explosion/burst into pixels or pixel's block, check the demo demo_burst and
demo_burt_exp (experimental version with _sdl library).
Tools for disassembling or reassembling images from exploded pixels
Added pixel_block_rgb (extract sprites from a sprite-sheet)
Added surface_split used by burst method to decompose an image into pixel blocks)
Added burst (explode a Pygame surface into multiple sub-surface )
Added display_burst (Display an exploded image on the Pygame display)
Added rebuild_from_frame (Rebuild an exploded image)
Added burst_into_memory (Burst image in memory)
Added rebuild_from_memory (Rebuild image from memory)
-- experimental with _sdl library--
Added burst_experimental (explode a surface into multiple sub-surfaces)
Added db_experimental (display burst)
Added rff_experimental (rebuild from a specific frame number)
Added rfm_experimental (rebuild from memory)
Added build_surface_inplace (build a surface from a sprite group inplace)
Added build_surface_inplace_fast (build surface from a sprite group, same than above but faster)
New library Sprites
This is the Pygame sprite module Cythonized
Library misc
New algorithm for scrolling surfaces or arrays, check demo demo_scroll
Added scroll24 (scroll surface horizontally / vertically)
Added scroll24_inplace (same but inplace)
Added scroll24_arr_inplace (same but for 3d arrays)
Added surface_copy (equivalent tp pygame surface copy)
Library Palette
Changed the palettes arrays to with dataset float32 types
Changed C file Shaderlib.c to perform fast math operations instead of double precision
