TestTileSource
✓ from large_image_source_test import TestTileSource
Direct import from source module.

Create a test tilesource and fetch the top-left tile at zoom 0.

from large_image_source_test import TestTileSource source = TestTileSource(tileWidth=256, tileHeight=256) tile = source.getTile(0, 0, 0) print('Tile shape:', tile.shape)
Debug
Known issues
gotchaThe test source generates fractal images, not real microscopy or satellite imagery. It is for testing only.
fix
Use large-image-source-* for actual image formats.
affects: all
deprecatedThis source may not support all features of tilesources (e.g., metadata, region extraction). Check your feature compatibility.
fix
For a full-featured test, consider large-image-source-rgb8.
affects: >=1.32
gotchaThe source does not require any image files; it generates tiles on the fly. Do not expect it to read from disk.
fix
Use large-image-source-tiff or large-image-source-openslide for file-based sources.
affects: all
Errors
Common errors & fixes
ModuleNotFoundError: No module named 'large_image_source_test'
The package is not installed or the import name is wrong.
fix
Install with 'pip install large-image-source-test' and import as 'large_image_source_test' (underscores not hyphens).
AttributeError: module 'large_image_source_test' has no attribute 'TestTileSource'
The class may have been renamed or not exposed in the module's top-level.
fix
Check the module contents with 'dir(large_image_source_test)' and use the correct class name (e.g., 'from large_image_source_test import TestTileSource').
TypeError: __init__() got an unexpected keyword argument 'tileWidth'
Constructor parameters may differ from version to version; 'tileWidth' might be 'tile_width'.
fix
Use keyword arguments as per documentation: e.g., TestTileSource(tileWidth=256) – check the source for exact parameter names.
