  1. hello Im wondering if it is possible to process image in autoit like this 1. firstly there is colorfull wallpaper 2. Fill all colors (exception rose color) - with white 3. Fill rose color with black color I see Gdi functions have things to manipulate images https://imgur.com/a/lFdY26g
  2. Here are two functions to provide pixel-accurate height and width dimensions for a given string. The more commonly-used _GDIPlus_GraphicsMeasureString built-in UDF is problematic because it returns the width padded by roughly one en-space (for reasons related to the various ways Windows produces anti-aliased fonts). These are AutoIt translations of Pierre Arnaud's C# functions, described in his CodeProject article "Bypass Graphics.MeasureString limitations" The first is an all-purpose version that takes a window handle, string, font family, font size (in points), style, and (optionally) width of the layout column (in pixels) as parameters. The second, more efficient version is intended for applications where GDI+ fonts are already in use, and takes handles to the existing graphics context, string, font, layout and format as parameters. Both functions return a two-row array with the exact width [0] and height [1] of the string (in pixels). EDIT: (Note that some of the same anti-aliasing measurement issues still apply. I did my best to work around them, but the output of the function may still be off by a pixel or two. Buyer beware.) #include <GDIPlus.au3> #include <GUIConstantsEx.au3> ; #FUNCTION# ==================================================================================================================== ; Name ..........: _StringInPixels ; Description ...: Returns a pixel-accurate height and width for a given string using a given font, style and size. ; Syntax ........: _StringInPixels($hGUI, $sString, $sFontFamily, $fSize, $iStyle[, $iColWidth = 0]) ; Parameters ....: $hGUI - Handle to the window. ; $sString - The string to be measured. ; $sFontFamily - Full name of the font to use. ; $fSize - Font size in points (half-point increments). ; $iStyle - Combination of 0-normal, 1-bold, 2-italic, 4-underline, 8-strikethrough ; $iColWidth - [optional] If word-wrap is desired, column width in pixels ; Return values .: 2-row array.
