✓ from large_image_source_openjpeg import OpenjpegFileTileSource
✗ from large_image_source_openjpeg import OpenjpegTileSource

Open a JP2 file and read its metadata and a tile at level 0.

from large_image_source_openjpeg import OpenjpegTileSource ts = OpenjpegTileSource('path/to/input.jp2') print(ts.getMetadata()) tile = ts.getTile(0, 0, 0) print(tile.shape)
Debug
Known issues
gotchaThe underlying glymur library requires libopenjp2 to be installed on the system. Installing via pip alone will fail if the C library is missing.
fix
Install libopenjp2 via system package manager (e.g., apt install libopenjp2-7, yum install openjpeg2).
affects: all
deprecatedAs of large-image 1.34.0, Python 3.9 support was dropped. This source now requires Python >=3.10.
fix
Upgrade Python to 3.10 or later.
affects: >=1.34.0
gotchaThe source does not support all JP2 features; it may fail on images with certain color spaces or resolution reductions.
fix
Verify the image opens correctly; consider using large-image-source-tiff for more complex cases.
