If you set a limit to 0, the limit is disabled.

Fields

version: u8

max_image_size_pixels: u64

Limit on the maximum image size to avoid allocating too much memory. For example, setting this to 32768^2 pixels = 1 Gigapixels results in 1.5 GB memory need for YUV-4:2:0 or 4 GB for RGB32.

max_number_of_tiles: u64

max_bayer_pattern_pixels: u32

max_items: u32

max_color_profile_size: u32

max_memory_block_size: u64

max_components: u32

max_iloc_extents_per_item: u32

max_size_entity_group: u32

max_children_per_box: u32
