Can i view images in my design ??

[yousefsamy 1]

yea my question is can i view pics in my design and here is my source it is very simple :

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

$Form1_1 = GUICreate("Form1", 660, 444, 192, 145)
$file = GUICtrlCreateMenu("&File")
$open = GUICtrlCreateMenuItem("open"&@TAB&"", $file)
$save = GUICtrlCreateMenuItem("save", $file)
$Pic1 = GUICtrlCreatePic("", 16, 56, 561, 329)
GUISetState(@SW_SHOW)


While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE
            Exit
        Case $open
            ;here ,, is it right to allow me view images as i like or ?? 
            $o = FileOpenDialog("File Open", @DesktopDir , " TXT (*.jpg) " )
            GUICtrlSetImage( $Pic1 , FileRead( $o ) )

    EndSwitch
WEnd

Try:

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

$Form1_1 = GUICreate("Form1", 660, 444, 192, 145)
$file = GUICtrlCreateMenu("&File")
$open = GUICtrlCreateMenuItem("open"&@TAB&"", $file)
$save = GUICtrlCreateMenuItem("save", $file)
$Pic1 = GUICtrlCreatePic("", 16, 56, 561, 329)
GUISetState(@SW_SHOW)


While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE
            Exit
        Case $open
            ;here ,, is it right to allow me view images as i like or ?? 
            $o = FileOpenDialog("File Open", @DesktopDir , " TXT (*.jpg) " )
            GUICtrlSetImage( $Pic1 , $o)

    EndSwitch
WEnd

i want to know why it didnt run with fileread ??

FileRead reads the contents of the file, FileOpenDialog returns the filename and GUICtrlSetImage requires a file name, not the contents of the file.

Have a look here: http://www.autoitscript.com/autoit3/docs/functions/FileRead.htm

 

FileRead returns the binary/string read. @extended is set to the number of bytes/characters returned.

 

It is most ideal to use for text files, not images.

Thnx alot 4 you really great men here   ..

but can you tell me how to make the window auto size with the size of the image ?? 

[BrewManNH 1,152]

You need to find out the size of the image and then make the GUI the same size, or stretch the image if it's too small to fit.

[mpower 22]

This will resize the GUI and the Pic control to fit the image dimensions (with optional scaling):

expandcollapse popup

#include <EditConstants.au3>
#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#include <GDIPlus.au3>

_GDIPlus_Startup()

$iWidth = 500
$iHeight = 500

$iScale = 1 ;set scaling from 0.1 to x (e.g. 2 = scale image to 200% original size)

$hGUI = GUICreate("Form1", $iWidth, $iHeight, @DesktopWidth/2 - $iWidth/2, @DesktopHeight/2 - $iHeight/2)
$file = GUICtrlCreateMenu("&File")
$open = GUICtrlCreateMenuItem("open"&@TAB&"", $file)
$save = GUICtrlCreateMenuItem("save", $file)
$hPic = GUICtrlCreatePic("", 0, 0, 0, 0)
GUISetState(@SW_SHOW)


While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE
            _GDIPlus_Shutdown()
            Exit
        Case $open
            ;here ,, is it right to allow me view images as i like or ??
            $o = FileOpenDialog("File Open", @DesktopDir , " TXT (*.jpg) " )
            ConsoleWrite($o&@CRLF)
            $hImage = _GDIPlus_ImageLoadFromFile($o)
            $iX = _GDIPlus_ImageGetWidth($hImage)
            $iY = _GDIPlus_ImageGetHeight($hImage)
            _GDIPlus_ImageDispose($hImage)
            WinMove($hGUI, '', Default, Default, $iX * $iScale, $iY * $iScale + 45)
            GUICtrlSetPos($hPic, 0, 0, $iX * $iScale, $iY * $iScale)
            GUICtrlSetImage($hPic, $o)
    EndSwitch
WEnd

Yea bro this is what i want  but what about [[ guiplus ]]?? what the benefit from it ?

please explain to me your codes i want to under stand  consolewrite , winmove ,,, and etc ...

ConsoleWrite($o&@CRLF)

This was here only for debugging purposes -  I was using this to see what value the variable $o was returning. To see it in action just run the script and watch the console in the bottom section of SciTE (assuming you are using SciTE to code).

You will notice that when you open an image the value of $o is the full directory path including the file name (e.g. C:WindowsExample.jpg).Alternatively you could display a MsgBox that shows the same thing: e.g. MsgBox(0,'',$o) would show a MsgBox with the text C:WindowsExample.jpg. ConsoleWrite is just a bit less intrusive, but both are good for debugging

It's definitely good to utilise ConsoleWrite whilst writing code to make sure you are working with the right values! 

GDI Plus is a library that works with images/graphics - someone has worked hard to write all the code for us to use to make it simpler. For example you could spend hours working our how to get the image dimensions but someone has already done this and has written a function called _GDIPlus_ImageGetWidth()

I don't really know much more about GDI Plus to be honest, I usually use these forums to find examples and also look at Help files (very important!!) You can actually click on every one of those functions right here in the forum and it would take you to a page explaining what each one does. That's the best place to start to understand how each function works.

WinMove allows us to change the size of the GUI (and even move the GUI around if we need to), but in our case we just resize the GUI to fit the image.

Hope this helps

yea your post really make me understand many things ,, but in help file with autoit i feel that i cant understand the example that's why i ask u :/  ,, right ?
