Where I can find the list of available property name for tesseract->setvariable function's first parameter?
提问by The iOSDev
From the lots of goggling I am able to find only few of them as the below example for tesseract's setVariable(1st param, 2nd param)
从大量的护目镜中，我只能找到其中的几个作为 tesseract 的 setVariable(1st param, 2nd param) 的以下示例
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");
I would like to know how much more of them are there?
我想知道他们还有多少？
Is there any list available? If any please give me the link to it.
有可用的列表吗？如果有请给我链接。

This code should do the trick for iOS... might need a bit of tweaking.
这段代码应该对 iOS 有用……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);
}
