Thanks for you reply. And I have another question.when I read the part of source code in libraw_cxx.cpp, the part of source code is :
char name[100], value[100];
utf2char(P[i].name,name);
utf2char(P[i].value,value);
if (!strcmp (name, "ISO"))
imgdata.other.iso_speed = atoi(value);
I am confused with this part of source code. when you developed this libraw library,how can you read "ISO speed" from Raw file to iso_speed variable of libraw?
