nara 0.1.1.9040 2026-05-02

• [9041] draw_mode removed in favour of use_alpha as XOR drawing - which is required for AnotherWorld rendering - is no longer supported.
• [9041] Tidy nr_desaturate()
• [9040] Add triangle drawing nr_tri_mesh(), nr_tri_coords()
• [9039] Tidy. Rename nr_duplicate() to nr_copy()
• [9038] Color reduction: nr_dither(), nr_desaturate(), nr_threshold()
• [9037] Masked rendering
• [9036] ignore transparency if !use_alpha
• [9035] C API Redux
• [9034] can now select drawing mode on all drawing ops: “respect_alpha” or “ignore_alpha”
• [9033] most line drawing operations now take a linewidth argument
• [9032] nr_copy_into() now supports a mask
• [9031] merged blit-ortho and blit-rotozoom.
• [9030] rotozoom and blit are moving towards the same interface
• [9029] Refactor draw commands. Argument ordering is now always (x, y), (w, h) in both C and R
• [9028] Add nr_blit_rotozoom()
• [9027] Add nr_blit_bulk()
• [9027] Blit refactor - remove nr_blit_list(), nr_blit_grid()
• [9026] Use colorfast for color conversion
• Remove ‘isocubes()’
• Remove ‘op’ argument.
• Standardise argument ordering
• Remove ‘dino’ sprites
• Add ‘deer’ spritesheet and isometric landscape tiles
• str_cols_to_packed_cols() for transparent and NA_character now returns value equivalent to #ffffff00
• Add
  • nr_crop()
  • nr_flipv()
  • nr_fliph()
  • matrix_to_nr()
• Refactored color conversion routines.
• Fast conversions in C
  • array_to_nr()
  • nr_to_array()
  • raster_to_nr()
  • nr_to_raster()
  • magick_to_nr(), nr_to_magick()
• Optimized blitting operations in C
• Added blit3() and blit4() mega-blitters
• Fixed(?) off-by-one bug in blitter core
• Drop inspection of “channels” attribute all together.
• As of 0.1.1.9009 2024-06-08 coordinate system is now (0, 0) at top-left
• Fixed rendering of borders for rectangles when both color and fill are translucent.
• Rationalize ‘blit’ methods (still need C implementations)
• Move all ‘magick’ related functions into single R file. Include gif and mp4 output.
• Use fast hashed lookup for R color names like ‘red’, ‘blue’, etc
• Handle logical NAs as transparent color
• pass through more arguments for nrs_to_gif() and nrs_to_mp4()
• hjust and vjust added for
  • nr_blit()
  • nr_rect()
• added nr_blit_list() and nr_blit_grid().
• added nr_resize_nn() and nr_resize_bilinear(). nr_scale() is now a wrapper around nr_resize_nn()
• Fixed bug in polygon rendering
• Parse image sequences from magick into native raster images
• Export C functions for use in other packages via LinkingTo
  • draw points
• Enhanced nr_polygon() to process multiple polygons in a single call
