  1. POWhy isn't text anti-aliasing working, while using a SWT GC to draw text?
    text
    copied!<p>Right now my goal is to have anti-aliased text on my Labels. If my research was correct, SWT Labels do not natively support anti-aliasing on text, so my current workaround attempt is to create an image, turn text anti-aliasing on, draw my text to that image, then give that image to the Label.</p> <p>My current image drawing code is as follows:</p> <pre><code>Image image = new Image(Display.getDefault(), width, height); GC gc = new GC(image); gc.setAntialias(SWT.ON); gc.setTextAntialias(SWT.ON); gc.setBackground(background); gc.fillRectangle(0, 0, width, height); gc.setFont(font); gc.setForeground(foreground); int yPos = offset.y; for (String rawLine : lines) { String line = rawLine.trim(); Point lineSize = gc.textExtent(line); int xPos = offset.x; switch (alignment) { case SWT.RIGHT: xPos += width - lineSize.x; break; case SWT.CENTER: xPos += width / 2 - lineSize.x / 2; break; case SWT.LEFT: default: xPos += 0; } gc.drawText(line, xPos, yPos, true); yPos += lineSize.y; } gc.dispose(); return image; </code></pre> <p>I have had inconsistent results on two different computers: At work, the text in the resulting images appears as choppy as ever- as if text anti-aliasing wasn't even on. But at home, connected to my work computer via remote desktop, I saw exactly the results I wanted.</p> <p>Obviously I'd like things to work correctly on both computers, but I am currently stumped as to why they aren't. Each computer is running Windows 7, Eclipse v3.6.</p> <p>What could be the problem that is causing this inconsistency? And if my workaround is just absurd and I am completely missing an easier way, what is that way? Thank you for any help!</p>
