问题描述

禁止使用警告-"警告.无效的分辨率1 dpi.改为使用70.".当使用Tess4j进行OCRing时

Help in Suppress Warning- "Warning. Invalid resolution 1 dpi. Using 70 instead." when using Tess4j for OCRing

大家好，我想抑制在使用Tess4j进行OCRing时在控制台中抛出的警告.请帮忙.

Hi All, I would like to suppress the warning thrown out in Console when using Tess4j for OCRing. Please help.

Tesseract在内部使用Leptonica进行某些图像处理，Leptonica在控制台上对此进行了介绍.

Tesseract uses Leptonica for some image processing internally and Leptonica thows this on console.

TIA

推荐答案

解决方法:并非来自Leptonica(lept4j)，而是来自Tesseract(tess4j).如果图像的分辨率小于70，则设置分辨率".

A Workaround: Not from Leptonica(lept4j) but from Tesseract(tess4j) way. Setting the Resolution if the resolution of the image if it is less than 70.

    TessAPI1.TessBaseAPISetImage2(handle, pix);
    //To remove the warning message "Warning. Invalid resolution 1 dpi. Using 70 instead." Setting the resolution
    int  res = TessAPI1.TessBaseAPIGetSourceYResolution(handle);
    if (res < 70) 
        TessAPI1.TessBaseAPISetSourceResolution(handle, 70);
