Richard Suchenwirth 2005-11-15 - Here's a simple effect to make canvas text items look nicer: the text is drawn twice, slightly shifted by a pixel in x and y direction. The font used should best be not the regular small one.
package require Tk proc shadedtext {w x y fg bg args} { eval [list $w create text $x $y -fill $bg] $args eval [list $w create text [incr x -1] [incr y -1] -fill $fg] $args }
## Demo:
pack [canvas .c] shadedtext .c 10 30 yellow black -text hello -font {Times 36 bold} -anchor w shadedtext .c 10 80 orange red -text world -font {Times 36 bold} -anchor w
UK I found a shift of two pixels nicer looking.
And you can have it even more fancy with a third level colored in the canvas bg-color layered in between:
proc shadedtext3 {w x y fg bg args} { set cbg [ $w cget -bg ] eval [list $w create text $x $y -fill $bg] $args eval [list $w create text [incr x -2] [incr y -2] -fill $cbg] $args eval [list $w create text [incr x -1] [incr y -1] -fill $fg] $args }
KPV I discovered accidentally that you can get a very nice embossed look if swap the ordering of the last two create text in shadedtext3.
proc EmbossedText {w x y fg bg args} { set cbg [ $w cget -bg ] eval [list $w create text $x $y -fill $bg] $args eval [list $w create text [expr {$x -3}] [expr {$y -3}] -fill $fg] $args eval [list $w create text [expr {$x -2}] [expr {$y -2}] -fill $cbg] $args } ## DEMO pack [canvas .c -bg green4] EmbossedText .c 10 30 yellow black -text hello -font {Times 36 bold} -anchor w EmbossedText .c 10 80 yellow black -text world -font {Times 36 bold} -anchor w
