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();
