resize images to reduce size

[rajah]

hello

first sorry about my bad english

i'm working on a little project a couple weeks ago, and i'm stuck on a little problem

i'm noob in autoit soi hope that i can found a solution here

this is my code

#include <ScreenCapture.au3>
#include <FTPEx.au3>
$iQuality = 30
$slp = 5000
$random = Random (1,987654,1) ; generate a random file name


    $host = "host.something.com"
    $user = "username"
    $pass = "mypassword"
    $public = ""
    $folder = "livestream/images/"
    $open = _FTP_Open("MySQL Upload")
    $conn = _FTP_Connect($open, $host, $user, $pass, 0, 21)
    $select1 = @ScriptDir &"/" &$random&".jpg"
While 1
_ScreenCapture_SetJPGQuality ( $iQuality )
_ScreenCapture_Capture (@ScriptDir &"/" &$random&".jpg")
_FTP_FilePut($conn, $select1, $public & $folder & $random & ".jpg")
Sleep ($slp)
_FTP_FileDelete ($conn, $folder  & $random & ".jpg" )
FileDelete ( @ScriptDir &"\" &$random&".jpg")
WEnd

 

a simple code, i call it a live streaming

so, i can navigate to www.site.com/streaming.php and keep watching the images progress.

the problem here is i can't resize the pictures, and i have a big screen, so each frame is about 950kb

so the stream is extremly laggy !

even when i reduce the quality of the capture, i can't make it smaller

the question is

how can i resize images? i dont care if i lost the quality.

THANKS

Have a look in the helpfile to _GDIPlus_ImageResize() and _GDIPlus_ImageSaveToFile()

[rajah]

already done

can't understand anything ... i'm noob bro, that code up there took me about 1 month lol

and i can't find the easy way to do it

why not  _ScreenCapture_SetReolution or something like that ?

The example for _GDIPlus_ImageGetWidth in the helpfile does exatly what you want.

Here is a simple example of resizing an image and save it to file

#include <ScreenCapture.au3>

$iQuality = 30
$random = Random (1,987654,1) ; generate a random file name
Local Const $iW = @DesktopWidth, $iH = @DesktopHeight

_ScreenCapture_SetJPGQuality($iQuality)
$hCapture = _ScreenCapture_Capture()

_GDIPlus_Startup()
$hImage1 = _GDIPlus_BitmapCreateFromHBITMAP($hCapture)
$hImage2 = _GDIPlus_ImageResize($hImage1, $iW / 2, $iH / 2)
_GDIPlus_ImageSaveToFile($hImage2, @ScriptDir &"/" &$random&".jpg")

_WinAPI_DeleteObject($hCapture)
_GDIPlus_ImageDispose($hImage1)
_GDIPlus_ImageDispose($hImage2)
 _GDIPlus_Shutdown()
