OcrConfig

Struct OcrConfig 

Source
pub struct OcrConfig {
    pub render_dpi: u32,
    pub trigger: OcrTrigger,
    pub min_text_length: usize,
    pub min_confidence: f32,
}
Expand description

OCR 处理器配置。

控制渲染 DPI、OCR 触发条件和质量阈值。

§Examples

use easypdf_markdown::ocr::{OcrConfig, OcrTrigger};

let config = OcrConfig {
    render_dpi: 300,
    trigger: OcrTrigger::Always,
    min_confidence: 0.8,
    ..OcrConfig::default()
};
assert_eq!(config.render_dpi, 300);

Fields§

§render_dpi: u32

页面转图像的渲染 DPI。默认值:200。

值越高 OCR 准确度越好,但内存占用和处理时间也越大。 200 DPI 对大多数文档是较好的平衡点。

§trigger: OcrTrigger

OCR 触发条件。默认值:OcrTrigger::OnEmptyPage

§min_text_length: usize

从 OCR 结果中保留的最小文本长度。默认值:0(全部保留)。

短于此阈值的 OCR 结果将被视为噪声而丢弃。

§min_confidence: f32

最小置信度阈值。默认值:0.5。

置信度低于此值的 OCR 结果将生成警告。
