(apply a Blur filter and set the blur amount to 0 will not blur the text)<br /><br />remember! alpha values applied from the text field's fill color wont work with device fonts. you need to change the alpha value of the movie clip either from the properties panel or <span style="font-family:courier new;">_alpha</span> property using ActionScript.<br /><br />what if you can't place your text field inside a movie clip? then you'll have to apply a graphic filter to the text field and change the _alpha value using ActionScript. simple as placing the following ActionScript lines in frame actions.<br /><br /><span style="color:#ffffff;"><span style="font-family:courier new;">import flash.filters.*;</span><br /><br /><span style="font-family:courier new;">var dummyFilter:BlurFilter = new BlurFilter(0,0,0);</span><br /><span style="font-family:courier new;">myTextField.filters = new Array(dummyFilter);</span><br /><span style="font-family:courier new;">myTextField._alpha = 50;</span></span><br /><br />Note: in ActionScript 3.0 alpha values are always less than one. so 50 becomes 0.5.<br /><br />using this method you can make masks (with non-rectangular shapes) work with device fonts and apply transperancy to device fonts, animate them with fade like effects, etc.</p><p>but we still need a better device font rendering from Flash. hopefully in next release! :)</p><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/7549777464435205759-2858075549682359493?l=flashunlimited.blogspot.com' alt='' /></div>Channahttp://www.blogger.com/profile/04225832761635972820noreply@blogger.com3
