I want to see if krpano is right for me so I am attempting to make tiles of a 155000 x 7498 (1.2gp) image on Linux 64bit. On a TIF saved from photoshop, the first row or rows of tiles are OK, but at a scan line that may or may not be the 2 billion byte mark, it switches and each pixel is displayed forever repeating downward, even the watermark pixels. I have attached a crop from an example. I also tried smaller tiles.
So I saved the file into a PSB and unfortunately all I get is a big set of black tiles (with watermark.) I am aware that some older programs can't handle TIFs larger than 2gb, but this is the latest krpano tools just downloaded today. Photoshop CS2 is of course able to read and write the 4gb TIF and 6gb PSB.
It would be nice if kmaketiles could handle PNGs. For large panos, PNG with its compression often is able to come in under 2GB when TIF can't, and as such is much more compact than PSB or other formats. AutopanoPro makes PNGs and that's my usual choice when the width is more than 65K. Converting to PSB is slow because it takes Photoshop a long time to load and save these images. Another option, perhaps better in its way than handling just PNG would be to handle PPM, because the PBM toolkit has tools to stream out just about any format as PBM out stdout. Well, not PSB I think, alas. There is a pbm splitter, pamdice, which outputs ppm files that can then be converted to jpeg, I suppose, which could be used instead of kmaketiles.
My command line is: kmaketiles /local/photo/pano/bm10/dota-maga-360.tif "dt_%v_%0h.jpg" 2000
On another note: I see talk of krpano working with an already tiled image but don't see much more detail? Is krpano able to put all the tiles into a single file so you don't have to have a directory with 400 files in it? That would be nice? Presumably one could embed the seek locations of the tiles in the file into the xml or the start of the file, and then the tiles could be fetched with the HTTP "Range" feature. How does one do this?
