Cropping Images

[Jlack0700 0]

First Attempt : 0 replies

Cropping images rather than resizing on a GUI. I just need a possible / probable / impossible on this one. Any help appreciated here.

Possible.

Here is an example:

expandcollapse popup

#include "GUIConstants.au3"
#include <Math.au3>

$gui=GUICreate("test transparentpic", 200, 100)
$pic=GUICreate("", 80, 71, 10, 10,$WS_POPUP,BitOr($WS_EX_LAYERED,$WS_EX_MDICHILD),$gui)
GUICtrlCreatePic(@Systemdir & "\oobe\images\merlin.gif",0,0, 0,0)

GUISetState(@SW_SHOW,$pic)
GUISetState(@SW_SHOW,$gui)

Const $MAX_WIDTH = 80, $MAX_HEIGHT = 71

HotKeySet("{LEFT}", "left")
HotKeySet("{RIGHT}", "right")
HotKeySet("{DOWN}", "down")
HotKeySet("{UP}", "up")

Do
    Sleep(10)
until GUIGetMsg() = $GUI_EVENT_CLOSE

Func left ()
    $picPos = WinGetPos($pic)
    WinMove($pic,"",$picPos[0],$picPos[1],_Max($picPos[2]-10, 0),$picPos[3])
EndFunc

Func right()
    $picPos = WinGetPos($pic)
    WinMove($pic,"",$picPos[0],$picPos[1],_Min($picPos[2]+10, $MAX_WIDTH),$picPos[3])
EndFunc

Func down()
    $picPos = WinGetPos($pic)
    WinMove($pic,"",$picPos[0],$picPos[1],$picPos[2],_Min($picPos[3]+10,$MAX_HEIGHT))
EndFunc

Func up()
    $picPos = WinGetPos($pic)
    WinMove($pic,"",$picPos[0],$picPos[1],$picPos[2],_Max($picPos[3]-10,0))
EndFunc

See what happens when you press the arrow keys.

Thank you so much. You have no idea how much time you saved me with $WS_EX_MDICHILD that I was completely unaware of.

Also, I had thought about creating a seperate window but did not realize that window ordering allowed the child to permanently stay in front of the parent. Well, it does, but now I have found autoit can't handle multiple stacked child windows correctly in all regards (I already have one much more important one) so this method can't apply unfortunately.

Please, anyone, anything else?
