Issues with understanding the naming of "scene_bounding_box" and "scene_height_by_width" functions

[sebi06]

Hi,

i used the following function over the last days and got a bit confused by the naming for the following functions

• mosaic_scene_bounding_boxes(index=SceneID)

• scene_bounding_box(index=SceneID)

• scene_height_by_width(index=SceneID)

• 1st yields in a List with tuples for every tile of a specific scene = SceneID

• 2nd yields in a tuple for the first tile of a specific scene = SceneID with (xmin, ymin, width-of-tiles, height-of-tiles)

So why is the function called scene_bounding_box, because it does not return the BBox of the specific scene. Or did I misunderstood something here.

• 3rd returns the width and height of the tiles of the scene = SceneID. Is this correct and if yes, should it be calle scene_tile_height_by_width etc?

I tested this on a CZI file with 4 different scenes (different size and shape), where a single tile is always 640x640. The output is below. Or do I misinterpret the naming of those function. To me it looks like the term tile (many tile make up a scence)) is mixed up with the term scene (a scene has many tiles) a bit, isn't it?

Cheers, Sebi

Hi @sebi06, you are correct. When I first implemented this we really weren't supporting mosaic files and were working with subblocks that spanned a scene and thus the current naming is a little odd. I've started working on a 3.0 version and will address changes in there. Once I have the API in a PR I will add you as a reviewer if you don't mind. I appreciate your pointing this out.

I would rename:

• mosaic_scene_bounding_boxes(index=SceneID) -> get_all_mosaic_tile_bounding_boxes
• scene_bounding_box -> get_single_tile_bounding_info
• scene_height_by_width -> get_single_tile_height_by_width

All functions start with verb all props start with noun or static value:

• function to get image: get_image_data or is_supported_image
• property as shorthand for access to data: data or current_scene
