c# - Antialiased text is not antialiased and Cleartype text is very ugly in windows forms -


i have following c# code graphics bitmap on windows 7 64-bit

protected graphics getimagegraphics() {     var g = graphics.fromimage(image);     g.smoothingmode = smoothingmode.highquality;     g.interpolationmode = interpolationmode.highqualitybicubic;     g.textrenderinghint = system.drawing.text.textrenderinghint.cleartypegridfit;     g.fillrectangle(backbrush, new rectangle(point.empty, bounds.size));     return g; }

this used follows:

 protected override void redraw()  {     var g = getimagegraphics();      var path = roundedrectanglepath(shaperect, cornerradius);     g.fillpath(selected ? selectedbrush : brush, path);     g.drawpath(pen, path);      foreach(var pin in pins)         pin.value.render(g);      var labelmax = shaperect;     labelmax.inflate(-10, -10);      var fmt = textformatflags.horizontalcenter | textformatflags.verticalcenter | textformatflags.wordbreak | textformatflags.wordellipsis;     textrenderer.drawtext(g, task.symbol.label, font, labelmax, color.black, fmt);      fmt = textformatflags.left | textformatflags.top | textformatflags.singleline | textformatflags.wordellipsis;     textrenderer.drawtext(g, task.taskid, font, idrect, color.black, fmt); }

the image created copied screen using:

g.drawimageunscaled(image, bounds);

the resulting text ugly. rendered in solid black each pixel has been replaced 3 adjacent horizontal pixels (like old dot-matrix printer bold font)

if change textrenderinghint antialias or antialiasgridfit font rendered more without antialiasing (like singlebitperpixel)

what doing wrong?

the solution two-fold. hans pointed out, text not antialias transparent. other part of answer not use textrenderer on in-memory bitmaps described here https://stackoverflow.com/a/1578056/429328

javascript - Function overwritting -

is there way overwrite function or event handling in function? using addeventlistener, can have many event handlers on element want var test=document.getelementbyid("div"); test.addeventlistener("click",function(){alert("im first");},false); test.addeventlistener("click",function(){alert("im second");},false); // alerts "im first" , after "im second" but if want overwrite function/event example based on client width example this function one() { alert("first"); } function two() { alert("second"); } window.onresize = function() { var test = document.getelementbyid("div"); if (window.innerwidth > 500) { test.onclick = 1 } else { test.onclick = two; } } is possible in javascript? in case use effective little known approach. addeventlistener can accept object property handleevent event handler. in case it's easy overwr...
