[Flashcoders] BitmapData size limit
Anyone know why the 2880 pixel limit for either width or height of a BitmapData object? If the intention is to limit the amount of memory required (2880 X 2880 pixels would require about 24 Mb), then the limit should be on the total size of the image surely. Or is there some other reason for this that someone can explain? I wanted to create an image object 3500 X 300 pixels which will take up about 4 Mb - but I can't. Any thoughts?

Ooops! sorry - my bad maths - that 24 Mb should have been 32 Mb David On 6/10/2006, at 7:28 AM, Dave Wood wrote: Anyone know why the 2880 pixel limit for either width or height of a BitmapData object?

I wanted to create an image object 3500 X 300 pixels which will take up about 4 Mb - but I can't sure you can't. you gave your answer in the above quoted text. your limitation is 2880 px square. and 3500 beats that. just scale it down to 2880 and you should be fine, than you can put it in a mc and scale that one up. that should do the trick. micha ___ Flashcoders@chattyfig.figleaf.com To change your subscription options or search the archive: http://chattyfig.figleaf.com/mailman/listinfo/flashcoders Brought to you by Fig Leaf Software Premier Authorized Adobe Consulting and Training http://www.figleaf.com http://training.figleaf.com
Re: [Flashcoders] BitmapData size limit
Thanks for your response Micha this has to with other things. the 2880 px stuff is related to one single object, you can have as much object of that size as you want, as long as you have enough ram. I wanted to create an image object 3500 X 300 pixels which will take up about 4 Mb - but I can't sure you can't. you gave your answer in the above quoted text. your limitation is 2880 px square. and 3500 beats that. No I didn't give the answer. I can understand why 2880 X 2880 might be considered excessively big, but to have 2880 pixels as a limit for a single dimension is silly - unless there is some other reson I don't yet understand. And if another reason exists, then I want to understand what it is. For example, if I have an image object 2881 X 10 pixels, that would be only about 280 kb. Why can't I create such an object? I don't want to scale my image up because I know it will degrade. Thanks David just scale it down to 2880 and you should be fine, than you can put it in a mc and scale that one up. that should do the trick. micha ___ Flashcoders@chattyfig.figleaf.com To change your subscription options or search the archive: http://chattyfig.figleaf.com/mailman/listinfo/flashcoders Brought to you by Fig Leaf Software Premier Authorized Adobe Consulting and Training http://www.figleaf.com http://training.figleaf.com
Re: [Flashcoders] BitmapData size limit
Dave, I'm not sure if this is appropriate for your application, but I ran into a similar problem when creating a project using high-quality panoramic photos. The way I worked around it was by slicing up my image into 2880 px tiles, then re-assembling them with actionscript on the stage.

Re: [Flashcoders] BitmapData size limit
It is a hard limit of object within Flash. It is similar to the hard limit of image sizes within Director as well. It has nothing to do with memory use but rather they way the app and player were programmed. Charles P.

Re: [Flashcoders] BitmapData size limit
Hi Charles / Bill It is a hard limit of object within Flash. It is similar to the hard limit of image sizes within Director as well. It has nothing to do with memory use but rather they way the app and player were programmed. I wasn't aware of the limit in Director - any idea what it is? In Director.. newImage = image(6000,6000,16) -- bloody big put ilk(newImage) -- image put newImage.width -- 6000 In Flash var newImage = new BitmapData(3500,300) // not so big trace(typeof(newImage)) -- undefined trace(newImage.width) -- undefined Bill, what you described very similar to what I'm trying to do, in my case I have a set of 7 images each 500 X 300 and I thought I'd assemble them in a single panoramic imag, display it in a single movieClip and handle the scrolling with copyPixels and a mask What I'm doing now is just putting them into individual clips spaced 500 pixels apart and scrolling the parent clip behind a mask - not using BitmapData at all. Works OK I guess, just seems less tidy soehow:( Cheers David Charles P.

Hey all, I have what will surely be a simple question for you. I instantiated a filled up an Array in my Main Class. How can I read that Array in another Class?
