Comment on BitmapData.draw() by Jason

Yeah, it’s the applying the clipping *after* transforms that had me scratching my head. You can transform the blit, but the clipping rectangle doesn’t move, which throws a wrench into the works until you figure that out. The Adobe docs are less than good. Pfft!

Thanks for helping affirm what I had suspected.

The cliprect specifies the area of the source which will be clipped. It is applied AFTER the transform matrix is applied. The cliprect also only works on the positive region (this MAY have changed in the newer versions of Flex, though I haven’t heard any reports as such) so anything in the negative realm will get clipped as well.

Hope that helps
Daryl

Exactly what does the clipRect do?
I presumed it defined an area of the source to which the transform matrix would then be applied but not so.

e.g.
var drawing:BitmapData = new BitmapData(aRect, 0xAA8844);
var bitmap:Bitmap =
var transform:Matrix = new Matrix(19, 0, 0, 19, -9700, -13500)

var clipper:Rectangle = bitmap.bitmapData.rect;
drawing.draw(bitmap, transform, _board.draw(bitmap, transform, color, BlendMode.NORMAL, clipper, true);

Results in a clipped version of drawing.

I agree. 3D GUI systems have been experimented with for years, and I’m yet to see a single setup that has any advantage over a conventional GUI beyond “it’s prettier.” While it’s entirely possible that someone will eventually come up with a way of efficiently using the extra organisational elegance of a design in 3 dimensions, so far people have put very little thought into what can be done with them.

It is also true that without a series of conventions to fall back on with regards to things like item placement (just think: when was the last time you clicked an “OK” button that was at the top of a form?) design and use can become a lot more complex.

There was a *front-page* article in the mX a couple of weeks back about this ‘new’ system that showed web pages as 3D rooms… shows what they know about revolutionary technology (or the lack thereof). Bloody stupid.

Hi,

I have a website (http://designwithoutsleep.co/random) where I need to mask duplicated moveclips so they appear within a white rectangle on the stage.

I am pretty confused with this article due to my beginner level of Flash 8. Any ideas what I should do?
