Reply to discussion (solution)
There is no such font to change the font or copy the font file to the corresponding directory.
There is an arial font file in the drive C path.
I set putenv ('gdfontfath = C: \ windows \ fonts ');
Change to putenv ('gdfontfath = C: \ Windows \ fonts ');
Error: Warning: imagettfbbox () [function. imagettfbbox]: cocould not find/open font in E: \ AppServ \ www \ make_button.php on line 38
But there are indeed Arial font files in the folder.
Please help !~~~
Sorry
The error is always "Warning: imagettfbbox () [function. imagettfbbox]: Invalid font filename in E: \ AppServ \ www \ make_button.php on line 38 ".
Is the problem of font variables. Set
Putenv ('gdfontfath = C: \ windows \ fonts ');
$ Fontname = 'arial ';
Directly change
$ Fontname = 'C:/windows/fonts/arial. ttf'. it is case insensitive.
I also encountered this kind of situation. I also followed the steps on the 4 th floor of #, but the file name still failed to be found.
How do I write the backslash of the font path? \ or/? I tried several methods, but none of them work, and the font exists in the system.
