Drop the font to "windows/fonts" on win10
$font ='BlackoakStd.otf';
$c->setDefaultFonts($font);
Can work
but
In my project folder, "/lib/font"
$c->setSearchPath('lib/font');
$c->setSearchPath(os.path.dirname('lib/font'));
None of them can work
What should I do to read the font file in the project folder |

Hi afu,
The setSearchPath is only for loading image files. See:
https://www.advsofteng.com/doc_v51/cdphp.htm#BaseChart.setSearchPath.htm
Font loading has its own search path, which can be modified with the FONTPATH environmental variable. See:
https://www.advsofteng.com/doc_v51/cdphp.htm#fontspec.htm
For your case, instead of using an environmental variable, I suggest you just specify the full font path name, like:
$font ='/path/to/lib/font/BlackoakStd.otf';
Note that the path name is a file system path name. It is not a URL. The leading slash '/' refers to the root of the hard disk, not the root of the web document directory. If it is a relative path (like "lib/font/..."), it is relative to the current working directory, which may not be the current URL directory or the current directory of the script.
To avoid confusion, I suggest to use the full absolute path name. You can include code to detect the full path name of your project, then append "lib/font/BlackoakStd.otf" to the path.
