Image slicing / resizing

[dinodod]

I'm trying to make a project where I have several large images that I need to slice up into smaller pieces. I am looking around but I am not seeing anything in autoit that can handle slicing images. I've seen a post towards resizing an image but can this also be done in Autoit?

I need both functions if possible, preferable the 1st, image slicer.

Thanks!

Using Auto3Lib:

#include <A3LGDIPlus.au3>
#include <A3LScreenCap.au3>

Global $hBitmap, $hImage, $aSlice[4], $iSliceX, $iSliceY, $iI

; Capture screen
$hBitmap = _ScreenCap_Capture("")

; Initialize GDI+ library
_GDIP_Startup()

; Slice up into 4 parts
$hImage  = _GDIP_BitmapCreateFromHBITMAP($hBitmap)
$iSliceX = @DesktopWidth  / 2
$iSliceY = @DesktopHeight / 2
$aSlice[0] = _GDIP_BitmapCloneArea($hImage, 0       , 0       , $iSliceX, $iSliceY, $GDIP_PXF24RGB)
$aSlice[1] = _GDIP_BitmapCloneArea($hImage, $iSliceX, 0       , $iSliceX, $iSliceY, $GDIP_PXF24RGB)
$aSlice[2] = _GDIP_BitmapCloneArea($hImage, 0       , $iSliceY, $iSliceX, $iSliceY, $GDIP_PXF24RGB)
$aSlice[3] = _GDIP_BitmapCloneArea($hImage, $iSliceX, $iSliceY, $iSliceX, $iSliceY, $GDIP_PXF24RGB)

; Save slices
for $iI = 0 to 3
  _GDIP_ImageSaveToFile($aSlice[$iI], "C:\A3LSlice" & $iI & ".bmp")
  _API_DeleteObject($aSlice[$iI])
next

; Clean up resources
_GDIP_ImageDispose($hImage )
_API_DeleteObject ($hBitmap)
_GDIP_ShutDown()

is it possible to resize with anti-aliasing?

GDI+ has transformation (resizing) and anti aliasing functions, but I haven't got them built into Auto3Lib at the moment.

when will it be available?

btw: http://www.codeproject.com/cs/media/AntiAliasingIssues.asp (looks great, but its for .net)

PaulIA is author of Auto3Library but he has left it's development.
