I mean real MB (how many RAM does it take). You can calculate it like: height * weight * 3 (RGB) / 1048576.

I will eat my hat if your "1.12 mb image" is less than 32MB in RAM.

It dosn't matter about length, only real RAM size. 20000x500 will work OK, but 4000x4000 will fail.

Problem starts from 32MB images. Say, 1360x8160 is 31.75MB (works OK), 1400x8400 is 33.65MB (bigger than 32MB), 3600x3600 is 37MB.
But 3600x3600 works just as well now with 9.0.115 as it did before.
I have not tested larger on 9.0.115 but I did with 9.0.47 and that was the limit on it.

If the limit is mb it does not make sence that the 37mb cubeface works but not the 33 mb strip.

Yes, the dependence is even more interesting. I found another "magic" number: 8191 (2^13-1). Flash Player 9.0.115 can't load images bigger than 8191.

So, stripes has ratio 6x1, last number for them is 8191x1365 = 31.99MB
Rounded stripe (divided by 48) is 8160x1360.

Maximum spherical/cylinder image is 8190x4095.

Maximum cube face is 8191x8191. But you can load only 3 such a big cube face. Looks like the whole Flash Player's memory is restricted as well...

Default Are these bugs or features, Denis? Should we file bug reports?

Denis:

Are these bugs or features? Should we file bug reports with Adobe?

If so, do you know a URL to go to for bug reporting, and what would be a succinct description of the problem?

First off; I don't want anyone start eating their hats (being a hat man myself)... but here you can see examples of my testing:



First two don't work, while the bottom one does.

So from the looks of it, it could be due to the file size (MB) splitting somewhere in the range of 34,4 MB.

I took the same image, cut part of it's hight, leaving it at 8332 x 1018 pixels (and 24,2MB):



Does not work.

In order to make sure it's the length and not the file size, I cut the hight down to 10 pixels, keeping the original 8332 in lenght:



... and it doesn't work (note that the real file size is only 243,8 kb in size)

And finally I cut that last image of 10 pix in height down to 8191 in length, made it into a cylindrical pano, and it worked.

So from what I can judge from my tests, it's indeed the pixel lenght of the image that determins if it works or not.
Maybe I am blind for the obvious... and that would not be the first time , but I actually think I may be right (don't we all?)

Ok, so there is also a max filesize (in MB) limit. I was not aware of that at all. All I had figured out was the 8191 max limit in pixels. So we are both right (had not seen your latest posting before posting my above post).

2 Teddi: Yes, we are.
2 cheathamlane: I consider it as a bug. How we should make hi quality panoramas with only 8191 width images? In any case it's a bad practice to restrict some possibilities in lata Flash builds...

I was doing some testing last night, and here are results directly relating to this topic:

Quote:
Panos using 6 cubic faces

8191 x 8191 pixels 2 of 6 images load in browser.
7000 x 7000 pixels 4 of 6 images load in browser.
6700 x 6700 pixels 4 of 6 images load in browser.
6650 x 6650 pixels 5 of 6 images load in browser.
6603 x 6603 pixels 5 of 6 images load in browser.
6602 x 6602 pixels 6 of 6 images load in browser.

Equirectangular and Cylindrical images

8192x???? - And bigger do not load
So the maximum size of cubic faces (based on pixel size) would be 6602 x 6602 pixels.

The biggest acceptable images I used were 124,7 MB in real size each, or 748,2 MB for the cube. (29,3 MB on disk)



So the Flash limitation we had put over our heads by Adobe still allows big panos... for as long as cubic faces are used, rather than Equirectangular renderings, or Cylindrical photos, where the limit is very quickly encountered.

The following is pure nonsense. The pixel limitations won't magically disappear just because the images are inside a .mov file
Quote:
I have not done a test with cubic faces bigger than 8191x8191 pixels used as the base for a QT .mov rendering and have it FPP wrap up the .mov and display it in Flash... but that should be problem free as far as I can tell.... and Equirectangular and Cylindrical .mov renderings should be limitless as well.

If not... I am sure someone will correct me.

EDIT: I have been corrected and finally made the change here so people won't be confused by my words.

Default flash image length restriction

i also ran into this image length problem in flash. what i find strange is that on the same machine, in firefox my image won't show up, while in ie it does. if the problem is with a flash player, then why does it work correctly in one browser and not the other?
