Всем привет :smile:, как можно примерно перевести картинку с 1го формата в другой, например: Bmp > jpg, jpg > bmp, ico - png, png - ico .и.т.п...
А также чтоб можно было указать новый размер картинки пример: 1024х600 > 600х400...
Зарание спс :IL_AutoIt_1:

BMP в JPG:
Код:
#include <GDIPlus.au3>

Global $sImage, $hImage, $sCLSID

$sImage = FileOpenDialog("BMP to JPG", "", "BMP Image (*.bmp)", '', '', GUICreate(''))
if @Error  then Exit

_GDIPlus_StartUp()
$hImage = _GDIPlus_ImageLoadFromFile($sImage)
$sCLSID = _GDIPlus_EncodersGetCLSID("JPG")
_GDIPlus_ImageSaveToFileEx($hImage, @ScriptDir & "\AutoItImage.jpg", $sCLSID)
_GDIPlus_ShutDown()

Мне бы чтоб устанавливать новый размер...
и чтоб получалось примерно так:
Чтоб картинка не обрезалась, а сжималась(Уменьшалось)... 1024х600 > 400x200...
Чтоб от старой картинки не 400х200 отрезалось, а именно вся старая картинка уменьшалась, и умещалась на 400х200...
