Всем привет, нужна либа для обрезки\ресайза изображения. Чтобы в экспорте было Си API, чтобы не сложно было компилять и чтобы кроссплатформенное типа для Win\Lin, можно только x64. Собственно, есть чё?

Пробовал: 1) OpenCV - боль собирать в винде, экспорт на 80% в формате С++. 2) libmagic - чёт вообще не собралось через mingw, ну и не очень понял как резать фоточки.

Так выхлоп дай почитать.

Да например:

$ ./autogen.sh

  1. libmagic - чёт вообще не собралось через mingw, ну и не очень понял как резать фоточки.

В чём проблема? Можно вообще поставить MSYS2, накатить там пакет imagemagick, взять оттуда либу и хедеры.

https://imagemagick.org/MagickWand/resize.htm

ИМХО, если тебе нужно не слишком легковесное решение, которое жуёт все форматы, то стоит обратить свой взор именно на эту либу.

Лады, давай его посмотрим:

Хмм. Да. Документация забабахана по шаблону. А про изменения забыли написать. Но без autoconf точно ничего не получится. Я лично делаю так:

autoreconf -fiv
./configure --prefix=/usr
make

Так мне в Rust пихнуть надо, там с этим не всё так просто. Один из вопросов на собеседование - мол расскажите про ffi и как подключить С библиотеку к проекту Rust.
