How to place semibold text on graphic?

5 posts in this topic

I'm using  _GDIPlus_FontCreate to create Arial to write directly on a PNG.  Everything works, but the font's appearance is too light, with narrow lines.  For some reason _GDIPlus_FontCreate only offers 0=normal, 1=bold, 2=italic.  But I've tried Bold and the result is too heavy.  I need half way in between: Semibold, which is listed on the MSDN site as a choice: http://msdn.microsoft.com/en-us/library/windows/desktop/dd183499%28v=vs.85%29.aspx

Both _WinAPI_CreateFont and GUICtrlSetFont offer a setting for $FW_SEMIBOLD (600), which I've used in normal fields with good result.

Is there any way to specify Semibold when using the GDI+ method?  Or is there another way to place text on a PNG?

Thanks in advance for any assistance.;

I adapted the following simple demonstration from an example on these forums.  It uses the same GDI+ calls that my large script uses.

#include <GDIPlus.au3>
#include <GUIConstantsEx.au3>
#include <Misc.au3>
#include <WindowsConstants.au3>
#include <WinAPI.au3>

AutoItSetOption("MustDeclareVars", 1)
Global $_ATTRIB = 1, $_NAME = 2, $_SIZE = 3, $_WEIGHT = 4, $_COLOR = 7 ;  default values
Global Const $_TEXT = 0, $_WIDTH = 2, $_HEIGHT = 3 ; $aStringSize indices
Global $aStringSize, $hGUI, $hGraphic, $hBrush, $hFormat, $hFamily, $hFont, $tLayout, $aInfo, $sText
Main()

Func Main()

$sText = @CRLF & " This is sample text.  It is displayed in Arial font." & @CRLF & @CRLF &" The goal is to have this text displayed in SemiBold." & @CRLF & " (Weight = 600) "& @CRLF & @CRLF & " End"

_GDIPlus_Startup()
$_ATTRIB = 0
$_SIZE = 12
$_WEIGHT = 600
$_NAME = "Arial"
$aStringSize = _GDIPlus_MeasureString($sText, $_NAME, $_SIZE, $_ATTRIB)
;MsgBox(48, "", $_NAME & " " & $_SIZE & " " & $_WEIGHT & "  " & $_ATTRIB , 0)
If Not IsArray($aStringSize) Then Return -1

; Build GUI
$hGUI = GUICreate("GDI+ Font Test)", 600, 400)
GUISetBkColor(0xFFFFFF)
GUICtrlCreateLabel("Font: " & $_NAME & ", Size: " & $_SIZE & ", Attribute: " & $_ATTRIB & ", Weight: " & $_WEIGHT, 10, 10, $aStringSize[0], 20)

$hGraphic = _GDIPlus_GraphicsCreateFromHWND($hGUI)
$hBrush = _GDIPlus_BrushCreateSolid()
$hFormat = _GDIPlus_StringFormatCreate()
$hFamily = _GDIPlus_FontFamilyCreate($_NAME)
$hFont = _GDIPlus_FontCreate($hFamily, $_SIZE, $_ATTRIB)
$tLayout = _GDIPlus_RectFCreate(10, 30, 560, 360)
GUIRegisterMsg($WM_PAINT, "_WMPAINT")
GUISetState(@SW_SHOW, $hGUI)

; Message Loop
Do
Until GUIGetMsg() == $GUI_EVENT_CLOSE

; Clean up
_GDIPlus_FontDispose($hFont)
_GDIPlus_FontFamilyDispose($hFamily)
_GDIPlus_StringFormatDispose($hFormat)
_GDIPlus_BrushDispose($hBrush)

_WinAPI_RedrawWindow($hGUI, 0, 0, $RDW_VALIDATE)
EndFunc   ;==>_WMPAINT

Func _GDIPlus_MeasureString($sString, $sFont = "Arial", $fSize = 12, $iStyle = 0)
    Local Const $hFormat = _GDIPlus_StringFormatCreate()
    Local Const $hFamily = _GDIPlus_FontFamilyCreate($sFont)

Thanks for your response.  Unfortunately, I can't spot any reference to font weight (=400, 600, 800, etc).

What I do see is the same kind of statement:  _GDIPlus_FontCreate($hFamily, $fSize, 1)
But I don't see any mention of the kind of FW_Semibold parameter that MSDN references.

Does it have to do with the _GDIPlus_BrushCreateSolid()?  Could you point out a couple of statements that I should investigate?
