Graphical Email Signature Generator

1 post in this topic

I'm trying to create an application that will create an image-based signature for email. It will take as input a number of text strings like Full Name, Job Title, Phone/Fax, Company Logo (, etc.). The program would place those text strings and the logo in series, and generate an image of that series, like in the attachment.

I'm trying to use GDI+ to get it done, but I'm having some trouble with saving the image -- it just saves a black image. I'm not exactly sure what I'm doing wrong; if anyone can help that would be great OR if you can suggest another way of achieving the same results that would also be great.

Here is my code:

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

$mainwindow = GUICreate("Signature Generator", 400, 200, (@DesktopWidth / 2) - 200, (@DesktopHeight / 2) - 200)
GUISetState()

$fullnamelabel = GUICtrlCreateLabel("Name:", 10, 13, 40, 20, $SS_RIGHT)
$fullnameinput = GUICtrlCreateInput("", 55, 10, 165, 20)
$fullnamefont = GUICtrlCreateCombo("Arial", 225, 10, 120, 20)
$fullnamesize = GUICtrlCreateInput("12", 350, 10, 40, 20)
$fullnamesizeupdown = GUICtrlCreateUpdown($fullnamesize)

$titlelabel = GUICtrlCreateLabel("Title:", 10, 38, 40, 20, $SS_RIGHT)
$titleinput = GUICtrlCreateInput("", 55, 35, 165, 20)
$titlefont = GUICtrlCreateCombo("Arial", 225, 35, 120, 20)
$titlesize = GUICtrlCreateInput("12", 350, 35, 40, 20)
$titlesizeupdown = GUICtrlCreateUpdown($titlesize)

$phonelabel = GUICtrlCreateLabel("Phone:", 10, 63, 40, 20, $SS_RIGHT)
$phoneinput = GUICtrlCreateInput("", 55, 60, 165, 20)
$phonefont = GUICtrlCreateCombo("Arial", 225, 60, 120, 20)
$phonesize = GUICtrlCreateInput("12", 350, 60, 40, 20)
$phonesizeupdown = GUICtrlCreateUpdown($phonesize)

$faxlabel = GUICtrlCreateLabel("Fax:", 10, 88, 40, 20, $SS_RIGHT)
$faxinput = GUICtrlCreateInput("", 55, 85, 165, 20)
$faxfont = GUICtrlCreateCombo("Arial", 225, 85, 120, 20)
$faxsize = GUICtrlCreateInput("12", 350, 85, 40, 20)
$faxsizeupdown = GUICtrlCreateUpdown($faxsize)

$logolabel = GUICtrlCreateLabel("Logo:", 10, 118, 40, 20, $SS_RIGHT)
$logobutton = GUICtrlCreateButton("Browse", 55, 110, 335, 35)

$savebutton = GUICtrlCreateButton("Save", 55, 150, 335, 40)

$previewwindow = GUICreate("Preview", 400, 200, (@DesktopWidth / 2) - 200, (@DesktopHeight / 2) - 100 + 150, $WS_EX_TOOLWINDOW)
GUISetState(@SW_SHOW, $previewwindow)
$context = _WinAPI_GetWindowDC($previewwindow)
_GDIPlus_Startup()

$previewgraphic = _GDIPlus_GraphicsCreateFromHDC($context)
$brush = _GDIPlus_BrushCreateSolid (0x7F00007F)
$format = _GDIPlus_StringFormatCreate ()
$fontfamily = _GDIPlus_FontFamilyCreate ("Arial")
$font = _GDIPlus_FontCreate ($fontfamily, 12, 2)
$rectfont = _GDIPlus_RectFCreate (140, 100, 100, 20)
_GDIPlus_GraphicsDrawStringEx ($previewgraphic, "Hello world", $font, $rectfont, $format, $brush)
