Slider control to resize image

6 posts in this topic

I am trying to create a slider control that will resize a 3d model (using IrrLicht) I understand how a slider works and how it's created and have done that. I understand how resizing the 3d model works and have done that. I can't seem to figure out how to combine the two to work together the way I want.

this is the resize syntax

ScaleMesh( node/3d model, x height, y height, z height )

$heightS=GUICtrlCreateSlider ( 0.15*@desktopwidth, 0.84*@desktopheight ,150,20)
    GUICtrlSetLimit($heightS,130/100,70/100)
    $height2=GUICtrlRead($heightS)
While 1
$msg = GUIGetMsg()
If $msg = $heightS Then
$height2=GUICtrlRead($heightS)
ScaleMesh( $toon, $height2, $height2, $height2 )
EndIf
Wend

obviously there is more code between. I've tried giving the guictrlsetlimit a set number but that doesn't work either.

Basically what is happening with the code above is the slider starts all the way to the left and only has an option to move all the way to the right (no in between) and (could be my math) but the image resizes way too big.

I would like the slider to start in the center and moving to the left makes the image smaller by 10% up to a -30% total, right makes it bigger at 10% inciments for a total of +30% total.

kaotkbliss,

Sliders cannot go above 100, so you have to play with the limits to get the return values you want.

In this script I have set the limits to 40 and 100, so all you have to do to get the % change you want is to add 30 to the result:

#include <GUIConstantsEx.au3>

$hGUI = GUICreate("Test", 500, 500)

$heightS = GUICtrlCreateSlider(10, 10, 150, 20)
GUICtrlSetLimit($heightS, 100, 40)

GUISetState()

$height2 = 70
GUICtrlSetData($heightS, $height2)
While 1
    Switch GUIGetMsg()
        Case $heightS
            $height2 = GUICtrlRead($heightS)
            ConsoleWrite($height2 + 30 & @CRLF) ; Just to show what you get <<<<<<<<<<<<<<
            ;ScaleMesh($toon, $height2, $height2, $height2)
        Case $GUI_EVENT_CLOSE
            Exit
    EndSwitch
WEnd

I hope this helps.

I'm at work right now and have been pretty scatterbrained the past few days being busy and everyone is on Holiday...

I thought I mentioned (but looks like I didn't) the ScaleMesh works on percents so a whole number makes the image bigger, a decimal makes it smaller.

to decrease the size by 10% the value would be .90 (new size= 90% of current size)

so even if you use min value on the slider as .70 and max as 30, if you decrease 2x you are now at -30% of original size then increase 10% then you are now at -40%

(-30%)---(-20%)---(-10%)---( 0 )---(+10%)---(+20%)---(+30%)

even if you set it all at -10% and +10% the same moves above still put you at -30%

I hope you understand what I am trying to say

kaotkbliss,

That was as clear as mud! :evil:

Do I understand that you need to apply the percentage change betwen the current value and the new one?

If so then this should work:

#include <GUIConstantsEx.au3>

$hGUI = GUICreate("Test", 500, 500)

$heightS = GUICtrlCreateSlider(10, 10, 150, 20)
GUICtrlSetLimit($heightS, 100, 40)

GUISetState()

$height2 = 70
GUICtrlSetData($heightS, $height2)
$Currheight2 = 70
$AbsoluteSize = 100

While 1
    Switch GUIGetMsg()
        Case $heightS
            $height2 = GUICtrlRead($heightS)

            $ChangeFactor = ($height2 + 30) / ($Currheight2 + 30)

            ConsoleWrite("Old Size: " & $AbsoluteSize & @CRLF & "Change Factor: " & $ChangeFactor & @CRLF & _
                         "Calc Size: " & $AbsoluteSize * $ChangeFactor & @CRLF & "Req Size: " & $height2 + 30 & @CRLF)

            $Currheight2 = $height2
            $AbsoluteSize = $height2 + 30
            ;ScaleMesh($toon, $height2, $height2, $height2)
        Case $GUI_EVENT_CLOSE
            Exit
    EndSwitch
WEnd

So if you change the current image by $ChangeFactor, you shoudl get the required 70-130% range.

Enjoy the holidays - when you get round to them. ;)

GREAT! thank you so much, while the sizes are a little off, I did get the slider to do what I wanted, now it is just a matter of tweeking the values. The $changefactor variable is what I placed into the ScaleMesh x,y,z values ;)

kaotkbliss,

There are probably small rounding errors at work in the maths - I did not take any great care over that. ;)

Glad I could help.
