Struct DetResizeForTest 

pub struct DetResizeForTest {
    pub resize_type: ResizeType,
    pub limit_side_len: Option<u32>,
    pub limit_type: Option<LimitType>,
    pub max_side_limit: u32,
}

A struct for resizing images for OCR testing

This struct encapsulates different resizing strategies for preparing images for OCR processing. It supports multiple resize types based on the input parameters.

Fields

resize_type: ResizeType

The type of resizing to perform

limit_side_len: Option<u32>

The length to limit the side of the image to (optional)

limit_type: Option<LimitType>

The type of limit to apply (min, max, or resize long) (optional)

max_side_limit: u32

The maximum allowed side length

Implementations

impl DetResizeForTest

pub fn new( input_shape: Option<(u32, u32, u32)>, image_shape: Option<(u32, u32)>, keep_ratio: Option<bool>, limit_side_len: Option<u32>, limit_type: Option<LimitType>, resize_long: Option<u32>, max_side_limit: Option<u32>, ) -> Self

Creates a new DetResizeForTest instance

This constructor determines the resize type based on the provided parameters. The resize type is determined in the following order:

1. If input_shape is provided, uses Type3
2. If image_shape is provided, uses Type1
3. If resize_long is provided, uses Type2
4. Otherwise, uses Type0 (default)

Parameters

• input_shape - Optional input shape (channels, height, width)
• image_shape - Optional target image shape (height, width)
• keep_ratio - Whether to maintain aspect ratio when resizing (used with image_shape)
• limit_side_len - Optional limit for side length
• limit_type - Optional limit type (min, max, or resize long)
• resize_long - Optional length to resize the long side to
• max_side_limit - Optional maximum side length limit

Returns

A new DetResizeForTest instance with the determined resize type and parameters

pub fn apply( &self, imgs: Vec<DynamicImage>, limit_side_len: Option<u32>, limit_type: Option<LimitType>, max_side_limit: Option<u32>, ) -> (Vec<DynamicImage>, Vec<[f32; 4]>)

Applies resizing to a batch of images

This method processes a vector of images, applying the configured resize operation to each one.

Parameters

• imgs - Vector of images to resize
• limit_side_len - Optional override for limit side length
• limit_type - Optional override for limit type
• max_side_limit - Optional override for maximum side limit

Returns

A tuple containing:

1. Vector of resized images
2. Vector of original image shapes and resize ratios [height, width, ratio_h, ratio_w]
