OpenCV：如何使用其他字体而不是HERSHEY与cvPutText（如Arial） [英] OpenCV: How to use other font than HERSHEY with cvPutText (like Arial)

问题描述

我想写一张图片格式化的文字。 OpenCV仅提供一组有限的默认字体。是否可以使用其他人？例如从* .ttf文件中读取它们（在Ubuntu中）？

I want to write to an image a formatted text. OpenCV offers only a limited set of default fonts. Is it possible to use others? For example to read them from the *.ttf file (in Ubuntu)?

推荐答案

可以使用其他字体但是你需要将Qt库链接到OpenCV并将cvAddText函数与cvFontQt一起使用

It's possible to use other fonts but you need to link the Qt library to OpenCV and use the cvAddText function with a cvFontQt

http://docs.opencv.org/modules/highgui/doc/qt_new_functions.html#addtext

您可以尝试其他解决方案，其性能与OpenCV大致相同。例如，您可以使用CAIRO将字体写入图像。

There are other solutions you might try, with more or less the same performance as OpenCV. For instance, you can use CAIRO to write fonts into the image.
