# coding: utf-8 =begin = Bitmap类拡张 (DLL版) RPGツクールXP/VX/VA共用 添加功能 Bitmap 类。 - Marshaldump 启用 - 保存为PNG文件 -色调变化 -马赛克效果 -反相颜色 -模糊效果 -使用遮罩-切除 -混合 ■ 注意 这个脚本需要"tktk_bitmap.dll"(ver0.1.2.6以上)。 Author:: 半生 Date:: 2010/12/13 Version:: 0.1.2.6 URL:: [url]http://www.tktkgame.com/[/url] ################更新######################## 2010/12/13 ver 0.1.2.6 dll名称从"hn_rg_bitmap.dll"变更为"tktk_bitmap.dll" LARGE_BITMAP机能でメモリを确保できなかった场合の処理を追加 2010/10/12 ver 0.1.2.5(デンジャラスベータ版) 大きいサイズのBitmapオブジェクトを机能を试験的に実装(危険) 2010/03/24 ver 0.1.2.2 ブレンディング机能関连の軽量化。 画像连结系メソッドの分离。 2010/03/24 ver 0.1.2.1 ブレンディング机能関连のバグフィックス 2010/03/22 ver 0.1.2.0 加算合成等のブレンディング机能の追加 2010/02/07 ver 0.1.1.0 マーシャル化の処理の一部をDLLに移动 2010/01/17 ver 0.1.0.0 dllの名称を"hn_rx_bitmap.dll"から"hn_rg_bitmap.dll"に変更 モザイク効果・色反転・ぼかし効果の追加 ############################################ =end module TKTK_Bitmap LARGE_BITMAP = true # 是否使用大型点阵图的功能 DLL_NAME = 'tktk_bitmap' ERROR_ALLOCATE_FAILED = -110002 @@png_save = Win32API.new(DLL_NAME, 'PngSaveA', 'p n i i', 'i') @@blur = Win32API.new(DLL_NAME, 'Blur', 'n i', 'i') @@change_tone = Win32API.new(DLL_NAME, 'ChangeTone', 'n i i i i', 'i') @@clip_mask = Win32API.new(DLL_NAME, 'ClipMask', 'n n i i i', 'i') @@invert = Win32API.new(DLL_NAME, 'InvertColor', 'n', 'i') @@mosaic = Win32API.new(DLL_NAME, 'Mosaic', 'n i i i i i i', 'i') @@address = Win32API.new(DLL_NAME, 'GetAddress', 'n', 'n') @@get_pixel_data = Win32API.new(DLL_NAME, 'GetPixelData', 'n p i', 'i') @@set_pixel_data = Win32API.new(DLL_NAME, 'SetPixelData', 'n p i', 'i') @@blend_blt = Win32API.new(DLL_NAME, 'BlendBlt', 'n i i n i i i i i i', 'i') #@@get_hwnd = Win32API.new(DLL_NAME, 'GetGameHWND', 'v', 'l') @@change_size = Win32API.new(DLL_NAME, 'ChangeSize', 'n i i', 'i') module_function # PNG形式储存 def png_save(bitmap,file_name,compression_level,filter) return @@png_save.call(file_name, bitmap.object_id, compression_level, filter) end # 模糊效果 def blur(bitmap, r = 1) return @@blur.call(bitmap.object_id, r) end # 更改颜色平衡?
