在哪里可以findtesseract-> setvariable函数的第一个参数的可用属性名称列表？
从大量的护目镜中，我只能find其中几个作为下面的例子tesseract的setVariable（第一参数，第二参数）
tesseract->SetVariable("tessedit_char_whitelist", "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ"); tesseract->SetVariable("language_model_penalty_non_freq_dict_word", "0"); tesseract->SetVariable("language_model_penalty_non_dict_word", "0"); tesseract->SetVariable("tessedit_char_blacklist", "xyz"); tesseract->SetVariable("classify_bln_numeric_mode", "1"); 我想知道他们还有多less？
有没有可用的列表？ 如果有的话，请给我的链接。
这个代码应该为iOS做窍门…可能需要一些调整。
bool verboseOut = true; if (verboseOut) { //Write to console current Settings char buffer [256]; FILE * pFile = tmpfile(); tesseract->PrintVariables(pFile); rewind(pFile); while (!feof(pFile)) { if (fgets (buffer,256,pFile)) fputs (buffer,stdout); } fclose(pFile); }
对于所有你感到沮丧的iOS编码器。 find头文件tesseractclass.h中的列表，这里是列表
