Re: Windows and OSX 64-bit builds?
This is a well known visual phenomena: When I'm tired I also switch sometimes 'in between reading' the temporarily memorized decimal point from the beginning to the end of a three-digit-block (did it recently in the forum). It mostly works for me (if not 'computing') to force myself to obey the rule, for the decimal prefixes, starting from Byte: Kilobytes = 10^3 Bytes => cut most right three MegaBytes = 10^6 Bytes => cut most right 6 (another three) GigaBytes = 10^9 Bytes => cut most right 9 (another three) TeraBytes = 10^12 Bytes => cut most right 12 (another three) As Phil hints, to use number words may be misleading here because 'billion' has different meanings in Europe (1 billion = 10^12) and in the USA (1 billion = 10^9). >> Bob S. wrote: >> Isn't it kBytes not bits?

Your labels are one order of magnitude off the actual values, Bob. Say it with me: 1,024,000,000 BYTES is "one billion bytes" (and change, depending on whose standard you use).

Re: Windows and OSX 64-bit builds?
I would second that, with an extension: it would be most helpful to have some guidance on memory management overall. Many see the total addressable space afforded by 64-bit systems as "Cool, I can use a 16-terabyte array!" But as we've seen in bits and pieces here and elsewhere, total addressable memory is not what LC will necessarily use, or can use, for many tasks. And it some cases it may not be what we really want to do. OS APIs impose their own limits, and many other factors can come into play as well. It would be useful to have at least some general guidance on what those limitations are, both in terms of LC as it is today and in terms where it bumps into system limits and general memory management challenges. Often these implications aren't obvious. For example, this morning I noted the difficulty with exporting an image of a 5000 X 5000 px button on Ubuntu. Later I tried a set of much smaller objects but spread out much more broadly (10k px and more), and LC remained very responsive throughout - even exported the snapshot fine. So I'm guessing from this that the difficulty with making unusually large standard controls was specific to how Linux' GDK handles them internally. Indeed, making LC-handled objects, like graphics, apparently have no problem being rendered and buffered at such sizes. Rather than make this an attempt at an exhaustive study of memory implications (though I'd gladly read it, it would take too long to write), it might be nice if Mark could draw from examples he's seen in the community over the years to outline some of the more commonly requested scenarios. -- Richard Gaskin hh wrote: Please post this "Split it!"- answer, as it is, in LC's blog.

Currently, the engine implements 'export snapshot' by allocating a raster (32-bits per pixel) of the size of the snapshot you are making, rendering into it and then compressing it. So really the maximum size you could hope to snapshot is 16k x* 16k pixels as that requires 2Gb - the engine in general uses signed integer indicies, so the maximum memory buffer it can manipulate is 2Gb bytes. A 32-bit process would probably struggle to do that (due to only having around 2-3Gb of user address space to use) - as there is overhead in rasterization and then compression; but a 64-bit process should be fine. There is a bug here as (at least in this specific case) the engine should fail gracefully (as we know there is a hard limit in the size of an image the engine can process). As you correctly point out 32k x 32k comes in at 1Gb pixels - which at 24-bit RGB comes out at 4Gb of data. No 'normal' 32-bit application which isn't explicitly designed for manipulating huge images will be able to deal with something that size. I would expect applications such as Photoshop to be able to deal with them though since I believe their native raw storage format for images pages from disk as required (so you never have the 'whole thing' in memory at once - just the bit you are looking at / editing). One important thing to remember is that the amount of memory required to take a snapshot is (SOMECONSTANT * 4 * the number of pixels) in the rect of the snapshot (I've not checked but I would estimate 0 < SOMECONSTANT < 2) which means that you can get LiveCode to generate very large images, but you have to break the problem down by splitting up the snapshot into bands and probably use an external (command-line) tool to compress the image into your format of choice (how big an image such a tool can process, again, will be dependent on whether it needs to load the entire image into memory to compress it or not). Rough idea: repeat with i = 0 to pHeight / kBandSize import snapshot from rect (0, pWidth, i * kBandSize, kBandSize) write the imageData of the last image to file tOutputFile delete the last image end repeat After this you will have a very large file with the raw xRGB data in it, so you need to find a tool which can take raw 32-bit xRGB data (with specified order of the RGB), the width and height and process it into jpg or png or whatever format you require (I'm hoping others who know more about such things might be able to chime in here - ImageMagick has an arsenal of command-line tools, for example). Warmest Regards, Mark. P.S. There is a hard limit of co-ordinate magnitude in LC and thus the size of any object - 32767 pixels on any side of anything.

Curious about this, I ran a test in LC 9 with a new stack with one button containing this script: on mouseUp set the rect of me to 0,0,6000,6000 put specialFolderPath("desktop")&"/TestBigImage.png" into tFile export snapshot from me to file tFile as PNG end mouseUp On Ubuntu 14.04 w/8GB RAM I get the image file generated within seconds, but then LC takes another several seconds (almost a full minute!) with one CPU core maxed until it goes back to a normal idle. Worse, while writing this email I was switching back and forth between my email client and LC, and apparently resume also takes nearly a full minute of maxed CPU before I'm able to work. I'll run strace with that and file a bug report later to see what could be done, but back to your app's need: Is raster output the best option for your users? Even at 10k px that'll be a pretty big file, unwieldy in many image apps (and apparently prohibitive to export in the Linux version of LC currently). It would be tedious but not too difficult to write a CardToSVG function instead, giving your users a widely-supported vector format whose file will be only slightly larger than the stack it was generated from (relatively speaking; being a plain-text format I'd guess the output size would be a small multiple of the stack file size, but certainly far less than a raster representation of the same layout). I know Alejandro had written some SVG importers some time ago - anyone here have at least the beginnings of an SVG exporter we could build upon as a community project? -- Richard Gaskin Fourth World Systems Software Design and Development for the Desktop, Mobile, and the Web ambassa...@fourthworld.comhttp://www.FourthWorld.com ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode

Juts making "64-bit" versions of LC for OSX or Window will not magically fix all limits in LiveCode that exists. Many are based on a coded 16 bit or 32 bit bounds. When running into limits, it is better to report the specific limit - as a bug report at http://quality.livecode.com/ - rather than looking for 64 bit versions of the engine. It *may* be that 64 bit address spaces is needed to expand the limit, but the again, it may not. ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
Re: Windows and OSX 64-bit builds?
I will... if u wanna replicate...put an image on a stack..make it 32k x 32k .and try and do a export snapshot of the image, LC goes POOF... Trevor said tha last version of 8 (8.13) had some memory issues solves, so i will try to test is there too.

Re: Windows and OSX 64-bit builds?
10 K in resolution I'm going to do more tests with the 2 cache settings . compositor cache and image cache. increasing these definately lets me export snapshots of larger groups...but I have not succeeded in going past 10 K I can display up to 32k. but snapshot export just hard crashes Livecode as soon as it is triggered. 32,000*32,000*4 is 4GB+ .. I would like my customers to be able to output their content as large images. 10 k is large enough for now. ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode

I’m not really sure when the first versions will make a stable release but the work required to get things building on our build servers is on the go.
