I'd like to list the following resources which I've found very useful, most of this is from there:

GDI+ Classes

José Roca's GDI+ reference and forum

developpez, a french site but with in-depth explanation.

And a warm thanks to Sjaak Priester for his wonderful ColorMatrix tool and source which the ColorMatrix funtions are built on.

I've forgot ;), thanks to Paul Campbell (PaulIA) for the great UDF, Malkey, UEZ, trancexx, monoceres, and everybody else for posting generous GDI+ examples.

This UDF is just a wrapper around GDIPlus.au3 to include the rest of the exports.

Notes about error handling:

There exist two additional status variables to catch function status or error codes. $GDIP_STATUS contains the return value from the function and it's meaning can be examined in GDIPlusConstants.au3 for a short description. A few functions may also set $GDIP_ERROR variable to a value explained in the function description. This variable should be contained in conditional code only when it's set by the GDIPlus functions as $GDIP_ERROR is never cleared, only set on error.

Currently:

Great extensions of GDI+ library!

Maybe now dreams come true... :)

Thanks for sharing!

Nice. When you add descriptions it would be much nicer.

There is one thing I don't understand. It's:

If @error Then Return SetError(@error, @extended, 0)

I can see how could that be useful when you look to the future or whatever. But only with eyes closed.

That technique shouldn't be considered as a final solution.

Even though it seems smart, usually it's adding more confusion when debugging than it should. If the function is complex one (more than one DllCall) it's almost impossible to determine what's failing.

For example you have function _GDIPlus_FontCollectionGetFamilyList().

Let's say it fails for some reason. You check @error and it's 3. You check @extended and it's 0.

What failed?

Wouldn't be much better to do something like this?

If @error Then Return SetError($iRelativeErrorPosition, @error, 0)

Where $iRelativeErrorPosition would be number that would uniquely identify position of error inside the function.

Will wait for description of functions before rating it fairly :) .

PLEASE !! Can you give me an working example of using _GDIPlus_TextureRotateTransform or _GDIPlus_ImageRotateFlip function with .png image. Im now working on some project and using normal matrix transform is horrible (it is rotating entire graphics content [i mean the size of entire GC] not only my image, and calculating new position of image is some nightmare), Thank You ! :)

BTW those funcitons are really really great ! I hope that the can be implemented in some ne comming BETA some days ;)

Thanks for the tips. You're absolutely right and I know that, you can see somewhere in the functions definitions something like:

If $iData = 0 The Return SetError(1, 1, 0)

..or returning -1 but it'll not be the final solution. Yes I'm a bit lazy in my nature but when things need to be done, they'll be done sometime.

The most problematic thing about it is to find a uniform way not to make the Remarks and Return sections redundant with if that then that, anyway I'm now working on the function decoration and rewriting the code as necessary. Funny thing, at the end the decorations are going to triple the file size from 3k lines to 9k+ lines :) Just as my first post, it wasn't and isn't complete. Thanks again for the suggestions.

P.S. I'm not expecting a starting scripter to walk through each and every error possibility or even use error handling at all so if the user is using it, the user probably knows what may be wrong but this is not an excuse to write a bad function.

Link. Search José Roca's forum, you'll find examples for almost any function exported via GDI+, most of the examples, eventually, will be taken from there. Read the PowerBASIC code, it's closer to AutoIt than the C++ one.

Edit: You! B) Now I need to manage 4 different states... Is $GDIP_STATUS and $GDIP_ERROR in conjunction with @error and @extended sounds sufficient?. $GDIP_STATUS is set to the return value (if DllCall didn't fail) of the function when applicable, $GDIP_ERROR will be set to 0 always and to an increasing integer that specifies the nested GDI+ function that failed. Comments?

Here an example with _GDIPlus_HatchBrushCreate() function (53 fill patterns):

Nothing special but imho worth mentioning.

;Coded by UEZ 2009.12.06
#include <GDIplus.au3>
Opt("GUIOnEventMode", 1)

_GDIPlus_Startup()
Global $width = @DesktopWidth * 0.75
Global $height = @DesktopHeight * 0.75

Global $hwnd = GUICreate("GDI+: Filled Brushes by UEZ", $width, $height, -1, -1, Default)
GUISetOnEvent(-3, "_Exit")
GUISetState()

Global $graphics = _GDIPlus_GraphicsCreateFromHWND($hwnd)
_GDIPlus_GraphicsSetSmoothingMode($graphics, 4)

Global $brush[53]
For $i = 0 To UBound($brush) - 1
    $brush[$i] = _GDIPlus_HatchBrushCreate($i, 0xFF0000FF, 0xFFFFFFFF)
Next

$dx = Int($width / 8)
$dy = Int($height / 7)

_GDIPlus_GraphicsClear($graphics, 0xFF000000)

$k = 0
For $i = 0 To $height -1 Step $dy
    For $j = 0 To $width - 1 Step $dx
        If $k <= UBound($brush) -1 Then _GDIPlus_GraphicsFillEllipse($graphics, $j, $i, $dx, $dy, $brush[$k])
        $k += 1
    Next
Next

While Sleep(150)
WEnd


Func _Exit()
    For $i = 0 To UBound($brush) - 1
        _GDIPlus_BrushDispose($brush[$i])
    Next
    _GDIPlus_GraphicsDispose($graphics)
    _GDIPlus_Shutdown()
    Exit
EndFunc

Func _GDIPlus_HatchBrushCreate($iHatchStyle = 0, $iARGBForeground = 0xFFFFFFFF, $iARGBBackground = 0xFFFFFFFF)
    Local $aResult = DllCall($ghGDIPDll, "uint", "GdipCreateHatchBrush", "int", $iHatchStyle, "uint", $iARGBForeground, "uint", $iARGBBackground, "int*", 0)

    If @error Then Return SetError(@error, @extended, 0)
    Return SetError($aResult[0], 0, $aResult[4])
EndFunc ;==>_GDIPlus_HatchBrushCreate

Thanks to Authenticity for the additional GDI+ function. Currently I'm searching within the functions for some nice functions...

Have a nice Santa Claus

w00t :) Thanks for the example, better than what I could come up with, for sure.

Here is a little translated tool original written by Sjaak Priester. I've just translated it (not so good) but it's still good to show the ColorMatrix functions meaning:

#include <Constants.au3>
#include <GDIP.au3>
#include <GUIConstantsEx.au3>
#include <ScrollBarConstants.au3>
#include <GUIToolbar.au3>
#include <WindowsConstants.au3>

Opt('MustDeclareVars', 1)

If Not IsDeclared("SB_ENDSCROLL") Then Global Const $SB_ENDSCROLL = 8

Global $hToolbar
Global Enum $idOpen = 0x0400, $idSave
Global $aLables[5] = ["Contrast", "Brightness", "Saturation", "Hue", "Gamma"]

Unfortunately the fill functions (texture or patterns) are not as expected. It is only a static backround image and not real fill in object!

Did you mean FloodFill GDI API?

Here is my example for that:

Can I fill e.g. an area (in your example) with a texture (image) whereas the texture matches the area?

This UDF is just a wrapper around GDIPlus.au3 to include the rest of the exports.

History:

Update 06.12.2009:
 - Added a few ColorMatrix manipulation functions, see top of the page for acknowledges.
 - Added a few more examples to the ImageAttribute object.

Update 04.12.2009:
 - Added a few more examples for InstalledCollection, Graphics, GraphicsContainer.
 - Fixed _GDIPlus_GraphicsDrawRectangles and _GDIPlus_GraphicsFillRectangles functions
 - Fixed a few examples that used some old functions syntax

Update 03.12.2009:
 - Added function descriptions.
 - A few function definitions have been redefined to be consistent with return and parameters values.
 - No additional examples at the moment.

Thanks for sharing!

You have done big good work.

With all standard description headers you can add it as proposition for adding to standard includes, just make ticket for it on Trac.

I think lack of examples for all included functions is not problem here. There are many standard UDFs without examples already.

I'm looking forward to new Autoit's beta with this included :-)

UEZ

Now I looked at your code (EDIT: from post #9) and I tried to run it.

I think you should use _GDIPlus_GraphicsFillEllipse() with constant X,Y coordinates to achieve your goal.

Maybe prepare memory bitmap with all drawn elipses and in main cycle just use BitBlt from this memory bitmap for each elipse.

You mean my example above: #751337 ?

I tried also _GDIPlus_TextureCreate() and assigned an image but the image will be static in the background. If you try to fill it with _GDIPlus_GraphicsFillEllipse() you will see within the moving ellipse the image partly (clipping of coordinate where the moving ellipse is).

I guess the the idea behind the texture and the hatch brushes is that the area behind it should be static. What you're asking is more like:

I guess the the idea behind the texture and the hatch brushes is that the area behind it should be static. What you're asking is more like:

YES, exactly what I searched. I will try it also for the texture function! Well done!

How did you find the way?

Thanks,

While experimenting, but that was the first and only experiment anyway :)

I know think about adding the GDI+ v1.1 functions, mainly the effects and that, but it's not going to be part of the GDIPlus.au3 compliant, rather a different branch of GDIP.au3, call it GDIPlus11.au3 or something but I don't know. What you think? Example:

#include <GDIPlus.au3>

Global Const $GDIP_BLUREFFECT = "{633C80A4-1843-482b-9EF2-BE2834C5FDD4}"
Global Const $GDIP_SHARPENEFFECT = "{63CBF3EE-C526-402c-8F71-62C540BF5142}"
Global Const $GDIP_COLORMATRIXEFFECT = "{718F2615-7933-40e3-A511-5F68FE14DD74}"

By the way, GDI+ v1.1 is distributed on Vista machines and up, so it's another problem.

The thing is to understand the functionality of all GDI+ functions. The names are not always clear to me what function is behind. Experimenting is probably the best way to check it out.

GDI+ v1.1 would be nice, too. It is possible to do some image manipulation.

Great job Authenticity!

Thanks,

UEZ

...

The functions naming is, as Paul Campbell did: The object the particular function applies comes first, followed by the verb and optionally the object or structure it's expecting. for example, GdipDrawEllipse is not relating to the graphics by it's name but it for sure exposed by the Graphics object so it becomes: _GDIPlus_GraphicsDrawRect. Another example is the GdipAddPathRectangle which becomes _GDIPlus_PathAddRectangle. Can you give an example of such function naming ambiguity? In any case I guess that the function's description is very helpful as MSDN can be ;)

Thanks UEZ.

Thanks UEZ.

I mean not ambiguity of function names but rather comprehensibility of function names. E.g. _GDIPlus_BitmapCreateFromScan0() (description: Creates a Bitmap object based on an array of bytes along with size and format information). This function was not intuitively understandable for me before you showed the example.

Also there are some more functions where I don't know what they are doing exactly. In that case I've to search e.g. at MSDN for a detailed decsription.
