navit_resize_image: (new w, new h)

Read the equation

In navit_resize_image, this statement defines or updates (new_w, new_h). The displayed multiplication combines the source factors. For tensors this is elementwise unless the called operation explicitly performs a matrix contraction.

Terms & definitions

The recovered passage does not supply a separate symbol table. Read the source context for the notation used in this version; familiar letters may carry different meanings in other builds.

How it works

1. Read new_w, new_h as the quantity being defined or updated by this relation.

2. Applies the stated minimum, maximum, or clamp. These bounds are part of the actual operation.

3. Use this version’s variable definitions and update order. The same symbol may be assigned a different meaning in another build.

Assumptions & limits

Source recovery establishes that the expression appears in this record. Its mathematical validity, implementation behavior, and interpretation must be assessed separately. See the linked source and research notes for the checks available for this version.

Original context

s2 = patch_limit_on_one_side * patch_size / width
    s3 = patch_limit_on_one_side * patch_size / height
    scale = min(1.0, s1, s2, s3)
    new_w, new_h = max(1, int(width * scale)), max(1, int(height * scale))
    new_w = min(new_w, patch_limit_on_one_side * patch_size)
    new_h = min(new_h, patch_limit_on_one_side * patch_size)

new_w, new_h = max(1, int(width * scale)), max(1, int(height * scale))
