"Don't work" should be removed from the English language. WHAT is your desired outcome? WHAT are you seeing instead? At WHAT point in your code is it failing (you have ZERO error checking)? WHAT errors are you receiving? WHAT have you done to troubleshoot those errors? Help us help you.

In the case of ScreenCapture, a black screen appears when executed. For Rotate, it works only with flag 1 in the function, not the rest.

Here, with autoit3 (v3.3.14.3) the screen capture is working, (i'v added the rotation to the capture, as a test)

rotation is working as well (demonstrated by a new gui which is displaying the rotated image.

The function _GDIPlus_ImageSaveToFile does nothing. (even the example file (_GDIPlus_ImageSaveToFile.au3/_GDIPlus_ImageSaveToFileEx.au3) from autoit help does not save the picture, and i have changed the folder, to make sure that the script can write to it).

Here is the halbum2040's source (translated to english) with added test gui for rotation.

If you run the code, the rotate image does show a rotated image, but the ImageSave fails with @error set to -1 and @extendend set to 0

Dan_555,

with autoit3 (v3.3.14.3)

I suggest upgrading to 3.3.14.5:

As you can see ScreenCapture was one of the affected functions.

halbum2040 · July 9, 2020

Dan_555,

Thank you very much. I am very happy to add and annotate the functions in the code.
However, the Rotate function does not work properly.
If you put another value in the flag in the Rotate function, the change does not occur.
Thank you again for your concern.

Please check if this code does the rotation:

If it does the 1st time at your pc, then the problem is easily identified.

check the console output, when you run it (i mean clicking the rotation button) the second/3rd time.

Edit: This should unlock the locked file:

halbum2040 · July 9, 2020

Dan_555, this solution also helped me a lot.
The moving part of Rotate is really fantastic for me.
Writing your code seems to have been the basis for writing my code.
I don't mind, but I have a question.
I am curious to see if I can implement the function to save the screen captured image.
I'm very curious what code to put out if you can.

Dan_555 · July 10, 2020

Hmm, the whole code is yours. I'v only added some minor changes.

The rotating image was only to identify where the bug is, which would prevent the new images to appear or to be saved. (i leaved it there, because i wanted you to test it, but few minutes after the posting, i found the solution)

To save a captured screenshot, you can use:

_ScreenCapture_Capture(@TempDir & "\screenshot.jpg", 100, 100, 300, 300, False)

(and then load it).

P.S. I have a project (well someone (from this forum) left it open sourced and has not worked on it for a long time), which is handling with the gdi images, but it could not save the new images. And because i'm a beginner with Gdi/+ i leaved it on hold.

But solving the problems in your code, solved the problems in my project.

halbum2040 · July 11, 2020

Dan_555,
I am very grateful for your advice. Actually,
I wanted to know more about the routine that saves the image loaded in the Pucture control rather than the capture storage code.
Thank you again.

Dan_555 · July 12, 2020

Yes, i'm seeking for a way to save (or to access) it, but no success atm.

This is the best i came with, (skipped few of the temporary files).

I'v tried to rotate the whichever picture is in the $Pic Control, (if you uncomment the RotateCtrl($pic) from the Case $Slider) but it looks like the control does not return the handle to the picture (at least this is how i understand it).

Moreover, if you uncomment it, the Rotate S.Capt button does not do, what it should.

The Save Pic button causes the _GDIPlus_ImageSaveToFile to return @error #10 and extendend 2

I have read some of the posts, and they suggest something: to keep an handle of a image, which is set as the picture.

But i hope someone knows how to extract the picture, if it is set up, just like now.

Ok, at least i'v found a solution to save the image from the $pic control, thanks to UEZ.

Replace the whole save pic function with following code:

Func SavePic($id,$fname=@Tempdir & "\Test.jpg")
    Local $hHBITMAP,$hImage
    _GDIPlus_Startup()
    $pic_hWnd = ControlGetHandle($Form,"",$id)
    $pic_hdc = _WinAPI_GetDC($pic_hWnd)
    $hGraphic = _GDIPlus_GraphicsCreateFromHDC ($pic_hdc)

    ;$hHBITMAP = _SendMessage(ControlGetHandle($Form, "", $id), $BM_GETIMAGE, 0, 0, 1)
    ;CW($hHBITMAP)
    ;$hImage = _GDIPlus_BitmapCreateFromHBITMAP($hHBITMAP)
    ConsoleWrite($hImage & @CRLF)
    _GDIPlus_Save_to_Image($fname, $Form )
    if @error >0 Then
        Local $er = @error
        Local $ex = @extended
        cw("ImageSaveError " & $er & " / " & $ex)
    EndIf

    _GDIPlus_GraphicsDispose ($hGraphic)

Dan_555, the code you created and found is really great. This was the code I wanted.
However, when I put the code you wrote in my code, the result was to save the entire form, not just the Picture control.
I want to save only the images loaded in the Picture control.
However, you are respected for extending the scope to this point.

In the _GDIPlus_Save_to_Image, i had to use some arbitrary number for the $z variable, so it can capture the control only.

I suspect that this solution may not work on every windows correctly. (because of different theme settings/Different title height or whatever).

Therefore i had another idea, to use the screen capture on the pic control. This may work, as long as the pic control is fully visible.

Comment the 1st, and uncomment the second line

    _GDIPlus_Save_to_Image($fname, $Form, $id )
    ;controlscreenshot_to_Image($fname, $Form, $id )

in the SavePic function, to test it.

Dan_555, I put in the code you gave me and I got the result I wanted.

The way you use your own slide controls is creative. But I was curious.

I am wondering if it is possible to implement a function that shows the loaded image in its original size.

To do this, you'll have to remember and show the path after the image is loaded, but I'm wondering how to implement it.

Anyway, the method you showed me is very helpful for me. Thank you^^

Dan_555 · July 15, 2020

Hmm,

put this somewhere after include statements:

Global $loadedimg=""

then, in the loadimage function add, after the $g_hImage = _GDIPlus_ImageLoadFromFile($FileName) :

$loadedimg=$FileName

and you should have the path+filename of the loaded image.

Replace the $btnRotateImage case with:

Case $btnRotateImage ;if you click the rotate image button
            Local $tmpfilen = $loadedimg
            Rotate_Image($tmpfilen, $rota)     ; Execute image rotation function

And the $Slider1 with:

Case $Slider1
            $rota = GUICtrlRead($Slider1)
            GUICtrlSetData($SliderNr, $rota)
            Rotate_Image($loadedimg, $rota)

Now, the slider is automatically loading and rotating the last loaded image.

An example of how to display images can be found here: https://www.autoitscript.com/forum/topic/200086-display-png-images/?tab=comments#comment-1435398

Dan_555,

I tried it the way you told me and it works fine.

However, by writing a routine that shows the actual size and saves it again, the image is broken and saved.

This is the full source code I wrote. Please test it once.

Atm i'm busy with other things, so i'll look, maybe saturday or sunday for the sollution, if there is any.

You said,

However, by writing a routine that shows the actual size and saves it again, the image is broken and saved.

but i said, in a previous post:

In the _GDIPlus_Save_to_Image, i had to use some arbitrary number for the $z variable, so it can capture the control only.

You see, i had to manually adjust this variable, so that it captures the control.

And i said:

I suspect that this solution may not work on every windows correctly. (because of different theme settings/Different title height or whatever).

Which is, i guess, the case now.

The Original _GDIPlus_Save_to_Image function used:

$size = WinGetClientSize($hWnd)
        $w = $size[0]
        $h = $size[1]

To determine the size of the client window, and to save an image of the window.

In my next post, i had the idea to limit the capture to the pic control only, by getting the coordinates of it with

$size = ControlGetPos($hWnd,"",$id)

but the returned position is not the correct one.

you can see what it is capturing, If you set the $z to 0.

So i manually adjusted the $z to fit the $pic control, and added the $z calculation into

 _WinAPI_BitBlt($memDC, $x, $y, $w+$z, $h+$z, $hDC, 0, 0, 0x00CC0020) ;  0x00CC0020 = $SRCCOPY

but of course it does not work for other widows.

So, to get the real starting position of the control, the window title has to be, somehow, stripped out, and so to get the starting point of the Client area.

At least that is, what ill try when i have more time for debugging.

There is a post, which is talking about it, Here.

Ok, now (i think) i understand where the error was.

it was the,

  _WinAPI_BitBlt($memDC, 0, 0, $w, $h, $hDC, 0, 0, 0x00CC0020) ;  0x00CC0020 = $SRCCOPY

which needed the correct parameters.

Here is the (hopefully) working function.

Dan_555, it's good to enter the code you provided.

I know that you've been taking some time out of your busy schedule.

Thank you for that. Really hard work.

But I wanted to add another feature here.

I wonder if it is possible to make the photo symmetrical or adjust the transparency with Auto-It.

I know you're busy, but I'm sorry for taking another matter.

how to screen capture?
