Uh, Does AutoIt cann't convert?

You can convert between image formats, but the alpha channel in pngs will get lost I think.

#include <GDIPlus.au3>

Opt("MustDeclareVars", 1)

; ===============================================================================================================================
; Description ...: Shows how to convert a PNG file to JPG
; modified from script by Paul Campbell (PaulIA)
; ===============================================================================================================================

; ===============================================================================================================================
; Global variables
; ===============================================================================================================================
Global $sImage, $hImage, $sCLSID


; Initialize GDI+ library
_GDIPlus_StartUp()

; Load image
$hImage   = _GDIPlus_ImageLoadFromFile(@ScriptDir & "\Torus.png")
; Get JPG encoder CLSID
$sCLSID = _GDIPlus_EncodersGetCLSID("JPG")

; Save image as JPG
_GDIPlus_ImageSaveToFileEx($hImage, @ScriptDir & "\torus1.jpg", $sCLSID)

; Shut down GDI+ library
_GDIPlus_ShutDown()

But you can show png images in AutoIt. See the examples in

Program Files\AutoIt3\Examples\GUI\Advanced

and in various places in these forums.


Serial port communications UDF Includes functions for binary transmission and reception.printing UDF Useful for graphs, forms, labels, reports etc.Add User Call Tips to SciTE for functions in UDFs not included with AutoIt and for your own scripts.Functions with parameters in OnEvent mode and for Hot Keys One function replaces GuiSetOnEvent, GuiCtrlSetOnEvent and HotKeySet.UDF IsConnected2 for notification of status of connected state of many urls or IPs, without slowing the script.
