Add a bevel to image using GDIPlus

benners · June 21

I have a function that creates an image of a specified colour. The image is saved and all works OK. What I would like to know is if it is possible to add effects to the image using GDI+ or if it is not built for that. I want the final image to be bevelled akin to what a progress bar looks like.?

    Local $sImgPath = @TempDir & '\GDIp_Pbar' & $vColor & '.png' ; create a file path
    If FileExists($sImgPath) Then Return $sImgPath ; if it exists, don't re-create

I cannot image what you mean. Do you have an example how it should look like?

Here some progress bars:

Edited June 21 by UEZ

Well I obviously overestimated my abilities and underestimated GDI+. They're amazing, make mine look rubbish Initially I only wanted a progress with text for a gui project. I tried a simple label one but it flickered

#include <GUIConstantsEx.au3>
#include <StaticConstants.au3>
#include <WindowsConstants.au3>

$Form1 = GUICreate("Form1", 350, 50, 811, 345)

$Progress = GUICtrlCreateLabel("", 97, 10, 0, 20)
GUICtrlSetBkColor(-1, 0xBD1EA)

GUICtrlCreateLabel("SciTE.exe", 5, 5, 300, 23, $SS_CENTERIMAGE, $WS_EX_CLIENTEDGE)
GUICtrlSetBkColor(-1, $GUI_BKCOLOR_TRANSPARENT)

GUISetState(@SW_SHOW)

For $i = 1 To 300
    GUICtrlSetPos($Progress, 5, 5, $i, 22)
    Sleep(10)
Next

Exit

Then I searched the hdd and found one from progandy that met my needs. I set about trying to under stand it and modifying it. It works but I keep adding things. The one I used comes with some jpgs. I thought I could add any colour and make then look similar to those. The UDF I was making is not finished but I'll add in case it may help with the topic. Something I have done may affect your working code. It' s the first time I've dabbled with gdi so it's a case of fake it till you make it currently.

GDIpProgress.au3

@UEZ I'll probably incorporate the code from _GDIPlus_StripProgressbar.au3 instead of creating images. It will be easier to use colours. Is it possible to alter the code so that it can act as a marquee style as well. I would think it would need the widths modifying but I would have no idea where to start.

I am going to try and break up your code so it uses the array I have in mine. This would stop the need to delete the gdi resources, unless they need to be deleted every time?

benners · Monday at 08:50 AM

Well I managed to get the progress to act like a marquee style by altering this line

_GDIPlus_GraphicsFillRect($hCtxt, 0, 0, $fPerc / 100 * $iW, $iH, $hTextureBrush)

to

_GDIPlus_GraphicsFillRect($hCtxt, $fPerc / 100 * $iW, 0, 75, $iH, $hTextureBrush)

and altering the % value in PlayAnim. It does judder sometimes so that needs improving. The code that draws the stripes will need updating if I decide to keep them in marquee mode.

Thanks UEZ. I have learned a bit from butchering yours and ProgAndy's code , whether I remember it all after is another matter. I did use your code to create the bitmaps and then thought, why am I doing this just to get images. Your bars were better so just use those. The code I used to save was

Funny how the mind focuses on one thing without considering other alternatives. I eventually combined bit's of yours and Andy's to get somewhere near. The only issue I currently have is when the progress bar is a marquee style. Instead of a smooth transition from left to right, the image appears at 0 but at its width of 60 so it looks sudden. The opposite end seems OK. If I tweak the stating position, the end position is out by the same amount.

If you have time I would appreciate any help you can give on this last bit. I should be finished after that and a few more functions and tests. I have attached the udf. The bit that needs looking at is in the __MPB_RefreshProgress function.

Well after playing around with image sizes ,adding, subtracting etc. All it took to get a smoother marquee bar was to change

$nX to $nX - 60

and

If $iPcent > 100 Then $iPcent = 0 to If $iPcent > 145 Then $iPcent = 0 
$nX = ($iPcent = 0) ? (-60) : ($iPcent / 100 * $__g_avPBars[$iID][$eMPB_cWidth] - 60)

seems better

Looks nice.

I modified my example above a little bit:

Nice. I especially like the colour change/ pulsing effect. Thanks.

Add a bevel to image using GDIPlus
