Tạo thumbnail bmp bằng php
Lỗi chạy trên localhost hàm imagecreatefromwbmp và imagewbmp
Warning: imagecreatefromwbmp() [function.imagecreatefromwbmp]: 'images/BLT_untitled.bmp' is not a valid WBMP file in C:AppServwww est aofilehinh.php on line 33
Vậy khắc phục như thế nào?
Các bác hướng dẫn giùm

Nhưng cứ báo lỗi
Nhưng nếu làm cho tất cả các định dạng (jpg, gif, png) thì ok
Còn file bmp thì không được
Hàm này trả về
array(12) { ["GD Version"]=> string(27) "bundled (2.0.34 compatible)" ["FreeType Support"]=> bool(true) ["FreeType Linkage"]=> string(13) "with freetype" ["T1Lib Support"]=> bool(true) ["GIF Read Support"]=> bool(true) ["GIF Create Support"]=> bool(true) ["JPG Support"]=> bool(true) ["PNG Support"]=> bool(true) ["WBMP Support"]=> bool(true) ["XPM Support"]=> bool(false) ["XBM Support"]=> bool(true) ["JIS-mapped Japanese Font Support"]=> bool(false) }
Và hiện tại đang lỗi ngay file bmp
