View Full Version : Maximum Image Size in Layout?

I have to construct a high-res Earth image for a client. I found the newer Earth images at http://visibleearth.nasa.gov/ and downloaded and constructed the highest-res imagery they offer for color, bump, specularity, etc., plus made a nice atmosphere gradient ... but if I try to use an image map as large as what the Visible Earth site offers, Layout crashes. With 18 GB RAM (I know, that's probably my primary limitation), the largest images I've been successful in using so far are sized at only 21600 x 13500.

I made smaller tiffs from NASA's huge documents, which are up to 86400x43200 at their maximum size, reduced to 4 GB file size, or around 50000x25000, but Layout crashes when attempting to load these images.

I looked in the LW docs for maximum allowable image size, but found nothing.

Is there some "basic rule" regarding image sizes allowable in Layout? If I need to install more RAM, it's cheap and I will go for it.

Any help would be greatly appreciated.

Thanks. :+)

This seems like something for infinimap. Try out the demo version and see if it gives any results?

Thanks for that recommendation. I'll give the demo a whirl.

In the mean time, to find 11.5.1 Layout's limit for image size (or RAM's limit, as the case may be), I guess I'll just cruise as close to the crash-point as possible and hope for the best. Right now, with four 22Kx11K RGB images and one 40Kx20K grayscale image, Layout takes about 15 minutes to open the file, and forever to show VPR or to render ...

Wow... yeah... well... infiniMap is your savior! It should help with loading and renderingtimes quite much, yes. :)

Oh, by the way while reading the LW 11.5 manual I came across the answer to your original question. Here's an excerpt:

Maximum Render Resolution:

The maximum render resolution for 32-bit versions of LightWave is still limited to 16,000 x 16,000
pixels but now 64-bit machines can render images up to 100,000 x 100,000 pixels given enough
memory. Bear in mind that 100k x 100k is an extreme size. Just a blank image at this size requires
around 149 GB of memory - 100k x 100k x (RGBA @ 4 bytes per channel = 16 bytes)/(1024 x 1024 x
1024) = 149 GB). Also, anything above 30,000 x 30,000 pixels won’t load into versions of Photoshop
older than CS4.

I thought the question was maximum input image size into layout.... not maximum output image size?

I appreciate the responses and help.

I'm currently working with Michael Wolf to allow me to use Infinimap, which so far has failed to recognize and process any image formats (openexr, tiff, png), and then crashes Layout 11.5.1 ... I am currently stumped. But I know Mike is a crack developer, and I have confidence he will find the problem.

I dunno, but I have this sneaking suspicion that Photoshop CC (v. 14.0) is the culprit here ... it's just a guess, but I suspect that Photoshop is doing something weird when creating these images that Infinimap doesn't like. However, a 21K x 10.5K image that crashes Infinimap and then Layout, loads just fine directly into Layout, and renders too, albeit VERY SLOWLY.

So I await Mike's fix ... or ... tons more RAM???

... it's always something. :-/

On it... we'll get it to work. :)
