Dream - Support GDAL tools

Unfortunately image magick does not work when a dimension is larger than 30000 pixels.
GDAL tools seem to support bigger raster files, but the interface is different from convert.
I am trying to understand how can I tweak your great script to use them.
Cheers!

EDIT: I have portions of the script working with gdalinfo and gdal_translate. But they are tuned for my standard use case, and would need work for other cases. Anyway, would be happy to share them.

It' s PC tower running on Ubuntu 20.04 with 16GB RAM and free disk space, i5 CPU and GTX970 GC.
Any idea?

Slicing an 8192x8192 image made folder structure off-by-one for openseadragon

I used a square input file of exactly 2^13, and sliced with no command-line arguments. I got a file structure with folders 0...14, with a 128x128 image in 8/ and a single 256x256 image in 9/. Openseadragon seemed to expect that the image in 8 would be 256x256 and 9 would contain four tiles. I "fixed" by hacking the .dzi file to say the full image size was 8193x8193, or (better!), by removing folder 0/ and renaming all the other folders n/ => n-1/

Optimize size of DZI rendered

I am currently testing magickSlicer for converting large jpeg files to DZI. It works nice.

However, i am facing a problem with the size of rendered DZI. For exemple, for an orginal jpeg file weighting 10Mo, the rendred DZI folder weight 26.2Mo with default option (-w 256 -h 256).
If I change options width and height to 512x512 the DZI folder weight 18.3Mo. It is yet too big because I have to deal with a huge repository of large files.

I wish to know how can I manage options of conversion for getting a DZI folder weighting less or equals to the weight of original files.

Best regards.

php version

Could this converted to a php version?

Large .psb files

What is the largest we can go using this tool?
I have a 121 095 x 52 585 pixel image I am trying to convert
It seems to get stuck at level 4 of the zoom tiles

I tried smaller files and they work great

Support tile overlap for DZI

Specified in pixels. Default should be 1. Default tileSize should be 254.

Overlap is added to the size of a tile. So, a middle tile (with neighbors on all sides) with a tileSize of 254 and an overlap of 1 would have an actual size of 256 (254 + 1 for each side). A tile on the edge (with only 1 neighbor) would have an actual size of 255 (254 + the one neighbor side).

Each overlap row or column is basically taken from the side of the neighboring tile. It's like you sliced all the tiles up without overlap, but then just added rows and columns of pixels from each neighboring tile.

When i launch sh magick-slicer.sh DJI_0001.jpg i have response 👍

Have you a idea for resolve this ?
Thank by advance

Slicing appears off by 1px

Normally not really visible, I think this is only exaggerated on the diagonal lines we have on the image itself.

Have tried multiple options but every set of images appears to result in the same thing happening. Any ideas?

This is in use with Open Sea Dragon, and effect is only visible when zoomed it at least 5 times.
