Re: [Flashcoders] Random incriments [AS3]
Hi, This is possibly due to rounding errors. If you want the components to remain the same size, you should set the size of one using the size of the other... selectedImage.width *= 1.1; imgWidthVar = selectedImage.width; etc. Glen SJM - Flash wrote: Hi Guys Im writing an application where you can manipulate images increse/decrease size rotate flip etc... but i need to keep the actual image size in memory for outputing (following on to my 'Reading position info X, Y, H W' question).

Re: [Flashcoders] Random incriments [AS3]
Hi Glen thanks for your reply, this is a continuation really from what you told me about Pythagoras to do this i need the actual image height and width. Normally i would do it this way but when the selected image is rotated selectedImage will be wider than imageWidth and will not output the correct information.

Re: [Flashcoders] Random incriments [AS3]
Hi, I am a bit confused as to what you want to do... If you rotate the image, I think it will return the width and height of it's bounding box, but I think you are saying you want to shrink the bounding box so it matches your original size??? - If you do this, you will shrink the image too. I am guessing you are trying to store your original unrotated width and height of the image for later? But you can calculate your actual image size from the bounding box values you have too... From your diagram - I think you have X2 and X on the wrong axis - but using your variables and assuming 0, 0 is at the bottom left hand corner (it may not be in the Flash Player): w2 = Math.sqrt( (WIDTH - Y) * (WIDTH - Y) + (X2 * X2)); h2 = Math.sqrt(Y * Y + (HEIGHT - X2) * (HEIGHT - X2)); Look at Proof #4 on this page if you want to see what I mean. http://www.cut-the-knot.org/pythagoras/index.shtml HTH Glen SJM - Flash wrote: Hi Glen thanks for your reply, this is a continuation really from what you told me about Pythagoras to do this i need the actual image height and width.

Re: [Flashcoders] Random incriments [AS3]
Glen, no i do not want to shrink the image i just want to maintain the original valuesthen calculate the increas/decreas info (ie original W 100, H 80 + [1 click] = W 110, H 90) so i can use Pythagoras in asp to do its job as you mentioned!! ... I am guessing you are trying to store your original unrotated width and height of the image for later?... Yes i am, I am also tring to multiply the value at the sametime so i can output W2 H2 ... From your diagram - I think you have X2 and X on the wrong axis - but using your variables and assuming 0, 0 is at the bottom left hand corner... 0,0 is the XY point (top right of actual photo), X2 does not exist and i can not get the information, if i could then it would be great!

Re: [Flashcoders] Random incriments [AS3]
Hi, You can do some trigonometry to get the missing dimensions. The distance from 0, 0, to X,0 - top corner of your image = X2, the distance from 0,0 to 0, Y - the LH corner of your image = Y2: theta = selectedImage._rotation * Math.Pi / 180; //(How much your image is rotated in radians). X2 = _selectedImage._height * Math.sin(theta); Y2 = _selectedImage._height * Math.cos(theta); Glen SJM - Flash wrote: Glen, no i do not want to shrink the image i just want to maintain the original valuesthen calculate the increas/decreas info (ie original W 100, H 80 + [1 click] = W 110, H 90) so i can use Pythagoras in asp to do its job as you mentioned!! ...
