my $video_info = SDL::Video::get_video_info(); VideoInfo is only accessible "SDL::Video::get_video_info". This module only provides getters to the struct "SDL_VideoInfo". DESCRIPTION
This object is a read-only structure and is returned by "SDL::Video::get_video_info". It contains information on either the best available mode if called before "SDL::Video::set_video_mode" or the current video mode if called after "SDL::Video::set_video_mode". METHODS
hw_available $video_info->hw_available() # 1 if Hardware Accelerated Surfaces available Is it possible to create hardware surfaces ? wm_available $video_info->wm_available() # 1 if Window Manager available Is there a window manager available ? blit_hw $video_info->blit_hw() Are hardware to hardware blits accelerated ? blit_hw_CC $video_info->blit_hw_CC() Are hardware to hardware colorkey blits accelerated ? blit_hw_A $video_info->blit_hw_A() Are hardware to hardware alpha blits accelerated ? blit_sw $video_info->blit_sw() Are software to hardware blits accelerated ? blit_sw_CC $video_info->blit_sw_CC() Are software to hardware colorkey blits accelerated ? blit_sw_A $video_info->blit_sw_A() Are software to hardware alpha blits accelerated ? blit_fill $video_info->blit_fill() Are color fills accelerated ? video_mem my $video_mem = $video_info->video_mem(); Total amount of video memory in Kilobytes, should be accessed only if hw_available == 1, otherwise it is equal to 0 vfmt my $vd_pixel_format = $video_info->vfmt(); "SDL::PixelFormat" of the video device current_w, current_h $video_info->current_w(); $video_info->current_h(); Width and height of the current video mode, or of the desktop mode if "SDL_GetVideoInfo" was called before "SDL::Video::set_video_mode" (available since SDL 1.2.10) SEE ALSO
