AS3 Bitmap draw problems

[neoyagami]

Hi all,

Ive got an image stored in bitmapData object, and i want to split this image into 100 diagonal strips (at 45 degress) The problem im having is speed because im working on a transition where they have to slide in at that angle.

Solution 1:

Currently ive created a -45 deg rotate matrix on the initial bitmap object and then copyPixels 100 rectangular sections into induvidual movieclips, these are then rotated 45 degrees to create the diagonal strips (an the initial rotation makes the image look the right way up)

I'm using the Tweener classes for AS3, but tweening this is quite slow because of all the amount or movieclips onscreen.

Solution2

So i was wondering if i could draw directly to a new bitmap object, from my source bitmap object, Can i draw in diagonal regions? From what i can see copy pixels can only copy rectangles so i would have to copy this diagonal strip with the rest of the rectangle as transparent pixels?

maybe im over complicating this working at bitmap level
just wondering if anyone has played with diagonal masking?

The rectangle lets you choose the area you want to copy, the point is the top left of the were the rectangle will be after is 'pasted'
