GDI+ draw text in circle

[corgano]

Hello world, I looked around the form to draw a text in a circle around a point. I found this, but it's a bit too complex

My question: It's been 2-3 years since this was posted, has anyone done this in a simpler way? I need to draw it in a circle, not an ellipse, and using a regular $hPen returned from _GDIPlus_PenCreate(). this SHOULD mean you can do it with simpler code, but I could not find any other examples. Is there a simpler way to do this?

A circle is just an ellipse with the width and height being the same.

[UEZ]

I assume you don't mean something like #12 Rotating Letters from rather this: http://t1.gstatic.com/images?q=tbn:ANd9GcRSO0bkAFbMoX_MGz9s6yIoLK9oVy6VCXIFfpC-FMg6RqWkxtQy or?

@Richard Robertson - Circle makes it simpler, because you only need to specify x|y|radius instead of x|y|w|h

@UEZ - Yes, http://t1.gstatic.com/images?q=tbn:ANd9GcRSO0bkAFbMoX_MGz9s6yIoLK9oVy6VCXIFfpC-FMg6RqWkxtQy is exactly what I need. what is the simplest way to accomplish this?

If I find some time I will try to code it...

Br,

UEZ

[corgano]

Thanks.

[Richard Robertson]

Width and height are just the diameter which is radius times two.

[corgano]

@Richard Robertson - I know this. You could easily calculate it from that, but even if the code provided was for elipse, I would change the perams and add the calculations to make it circle only just for simplicity.

Well, it is a fast hack and beta!

I tried to keep code as simple as possible!

To do? E.g. real time rotation, color of letters, etc.

Have fun,

The rotation of the letters are currently still too "fitfully".

I hope I can fix it...

Lol it looks like you rotate each letter by itself, couldn't you draw all the letters to a single bitmap and just rotate the bitmap around it's center?

Of course I can but then you don't have the flexibilty to do some more effects on each letter!

You can print the rotated letters to the bitmap and rotate only the visible screen...

You've lost me. I've been trying to turn the first script into a function (I need to call it 3 times with different prams at the beginning) but I failed epicly. I don't need to ever rotate the letters one by one, I need only to draw them to a bitmap which I can rotate. Help?

@UEZ

If you plan to make a more complex version of this, the thread I linked to in post 1 used this to get the width of each character. This code may be useful to calculate letter angles in instances where you have multiple "skinny" letters, like llllll or iiiiiii. However, this functionality is not useful for my script.

For $n = 1 To $aChar[0]
        ;ConsoleWrite($n & "  " & $aChar[$n] & "  Width = ")
        $hFormat = _GDIPlus_StringFormatCreate(0)
        $hFamily = _GDIPlus_FontFamilyCreate($nFontName)
        $hFont = _GDIPlus_FontCreate($hFamily, $nFontSize, 3, 3)
        $tLayout = _GDIPlus_RectFCreate(50, 50, 0, 0)
        $aInfo = _GDIPlus_GraphicsMeasureString($hGraphic, $aChar[$n], $hFont, $tLayout, $hFormat)
        $aCharAll[$n][1] = Ceiling(DllStructGetData($aInfo[0], "Width"))
        $aCharAll[$n][2] = Ceiling(DllStructGetData($aInfo[0], "Height"))
        If $aCharAll[$n][1] > $iMaxRectWidth Then $iMaxRectWidth = $aCharAll[$n][1]
        ;ConsoleWrite($aCharAll[$n][1 ]& " Height =  " & $aCharAll[$n][2] & @CRLF)
    Next

Question, What does _GDIPlus_BitmapCreateFromScan0 do?

Other then that, the code makes sense and I am able to use it. I'll have something to show you in a bit. Thanks UEZ!

Creating an empty 32bit bitmap.

From GDIp.au3:

; #FUNCTION# ====================================================================================================================
; Name...........: _GDIPlus_BitmapCreateFromScan0
; Description ...: Creates a Bitmap object based on an array of bytes along with size and format information
; Syntax.........: _GDIPlus_BitmapCreateFromScan0($iWidth, $iHeight[, $iStride = 0[, $iPixelFormat = 0x0026200A[, $pScan0 = 0]]])
; Parameters ....: $iWidth      - The bitmap width, in pixels
;                  $iHeight     - The bitmap height, in pixels
;                  $iStride     - Integer that specifies the byte offset between the beginning of one scan line and the next. This
;                  +is usually (but not necessarily) the number of bytes in the pixel format (for example, 2 for 16 bits per pixel)
;                  +multiplied by the width of the bitmap. The value passed to this parameter must be a multiple of four
;                  $iPixelFormat - Specifies the format of the pixel data. Can be one of the following:
;                  |$GDIP_PXF01INDEXED   - 1 bpp, indexed
;                  |$GDIP_PXF04INDEXED   - 4 bpp, indexed
;                  |$GDIP_PXF08INDEXED   - 8 bpp, indexed
;                  |$GDIP_PXF16GRAYSCALE - 16 bpp, grayscale
;                  |$GDIP_PXF16RGB555    - 16 bpp; 5 bits for each RGB
;                  |$GDIP_PXF16RGB565    - 16 bpp; 5 bits red, 6 bits green, and 5 bits blue
;                  |$GDIP_PXF16ARGB1555  - 16 bpp; 1 bit for alpha and 5 bits for each RGB component
;                  |$GDIP_PXF24RGB       - 24 bpp; 8 bits for each RGB
;                  |$GDIP_PXF32RGB       - 32 bpp; 8 bits for each RGB. No alpha.
;                  |$GDIP_PXF32ARGB      - 32 bpp; 8 bits for each RGB and alpha
;                  |$GDIP_PXF32PARGB     - 32 bpp; 8 bits for each RGB and alpha, pre-mulitiplied
;                  $pScan0      - Pointer to an array of bytes that contains the pixel data. The caller is responsible for
;                  +allocating and freeing the block of memory pointed to by this parameter.
; Return values .: Success      - Returns a handle to a new Bitmap object
;                  Failure      - 0 and either:
;                  |@error and @extended are set if DllCall failed
;                  |$GDIP_STATUS contains a non zero value specifying the error code
; Remarks .......: After you are done with the object, call _GDIPlus_ImageDispose to release the object resources
; Related .......: _GDIPlus_ImageDispose
; Link ..........; @@MsdnLink@@ GdipCreateBitmapFromScan0
; Example .......; Yes
