Hi All.
I am stuck and need some fresh ideas...
I am writing a script that checks to see if an Oracle db is available. The script reads an ini file to determine if there is a blackout period for certain db's... ie: we don't care if it's up or down 1700 - 700 the next morning.
The ini file... (3 Replies)
I was wondering what other mail utilities besides 'mutt, unix mail, PINE and elm' are available for unix.
Also, what other editors are around besides 'VI, pico, vim and emacs'... I've been searching the net looking for some answers, but nothing much has come up.. thanx! (1 Reply)
We are trying to tune a server which phsycially is maxed out on cpu.
We are maxing out on memory and swapping at a rate of 20-43% of our swap space which is approx 45% of total ram.
We "can" upgrade to twice the memory that we currently have but it will be costly as there are no more seats... (5 Replies)
Just started out with C and are looking for a good editor
in *nix that marks the code with colors.
This is maybe a newbie thing to have the C code in colors
but i like it and you can almost always se when you are typing wrong. :)
Ive heard that emacs should have that option but i havent... (3 Replies)
pods::SDL::Overlay(3pm) User Contributed Perl Documentation pods::SDL::Overlay(3pm)NAME
SDL::Overlay - YUV Video overlay
CATEGORY
Core, Video, Structure
SYNOPSIS
First import the following modules to get access to constants and functions needed for overlay.
use SDL;
use SDL::Video;
use SDL::Overlay;
Init the video subsystem.
SDL::Init(SDL_INIT_VIDEO);
Create a display to use.
my $display = SDL::Video::set_video_mode(640, 480, 32, SDL_SWSURFACE);
Create and attach the display to a new overlay
my $overlay = SDL::Overlay->new( 100, 100, SDL_YV12_OVERLAY, $display);
DESCRIPTION
A "SDL_Overlay" allows for video rendering on an "SDL_Surface" which is a display.
The term 'overlay' is a misnomer since, unless the overlay is created in hardware, the contents for the display surface underneath the area
where the overlay is shown will be overwritten when the overlay is displayed.
METHODS
new ( $width, $height, $YUV_flag, $display)
The constructor creates a SDL::Overlay of the specified width, height and format (see "YUV_Flags" list below of available formats), for the
provided display.
Note the 'display' argument needs to actually be the surface created by "SDL::Video::SetVideoMode" otherwise this function will segfault.
my $overlay = SDL::Overlay->new( $width, $height, $YUV_flag, $display );
YUV_Flags
More information on YUV formats can be found at <http://www.fourcc.org/indexyuv.htm> .
o SDL_YV12_OVERLAY 0x32315659 /* Planar mode: Y + V + U */
o SDL_IYUV_OVERLAY 0x56555949 /* Planar mode: Y + U + V */
o SDL_YUY2_OVERLAY 0x32595559 /* Packed mode: Y0+U0+Y1+V0 */
o SDL_UYVY_OVERLAY 0x59565955 /* Packed mode: U0+Y0+V0+Y1 */
o SDL_YVYU_OVERLAY 0x55595659 /* Packed mode: Y0+V0+Y1+U0 */
format
Overlay format (see YUV_Flags)
w, h
Width and height of overlay
planes
Number of planes in the overlay. Usually either 1 or 3
pitches
An array of pitches, one for each plane. Pitch is the length of a row in bytes.
pixels
As of release 2.3 direct right to overlay is disable.
An array of pointers to the data of each plane. The overlay should be locked before these pointers are used.
see SDL::Video::lock_YUV_overlay, SDL::Video::unload_YUV_overlay
hw_overlay
This will be set to 1 if the overlay is hardware accelerated.
