Drawing text without antialiasing


The sample shows how to draw a text string without antialiasing.
By default antialiasing is always turned on. Now you can draw text without antialiasing for palette images that were created with CreateImagePalette method, or created from GIF, PNG (8-bit) images, or converted using ConvertToPalette, ConvertToPaletteNoAlpha methods.

TextAntialias.vbs

' Define object variable
Dim im

' Create object
Set im = CreateObject("ActiveImage.Images.1")

width = 180
height = 60
' Create image with specified width and height
im.CreateImagePalette width,height
im.SetColor 255,255,255
im.DrawFilledRectangle 0,0,width,height

'Set path to true type fonts
im.SetFontPathTTFAuto
