cannot create png and jpg graphic

Anon

i have tried to use imagecreatefromjpeg() to create a jpg file but it does not work, no error message and no output, i don't know why, could you help me? i also try to use imagecreatefrompng to create png file, it also fails. My code are as follow🙁gd lib version is 1.6.2 or higher)

$dst_img = @ImageCreateFromJPEG("test.png");
if($dst_img){
$color = imagecolorallocate($dst_img, 0, 0, 255);

imagestring($dst_img, 5, 0, 0, "test", $color);
Imagepng($dst_img);
}

*note:test.png is ok

1) is $dst_img returning any value? the "@" before imagecreatefrompng is suppressing errors, remove that and see what happens.

2) have you tried to specify the full path to test.png? whats the permissions on test.png?

the permission of the test.png is 644.
I have tried to use both
@imagecreatefromgif() and
imagecreatefromgif(), both work. But imagecreatefrompng() will have a error message (ImageCreateFromPng: No PNG support in this PHP build in /usr/develop/tyeung/work/p1/public_html/test/test_image_png.php on line 52
) while @imagecreatefrompng() will not. @imagecreatefrompng() does not give any output....

check your gd version again. according to http://php.net/manual/en/ref.image.php gd version > 1.6 supports png but not gif.

adding "@" to imagecreatepng just suppresses the error, but the error is still occuring. from the error message it sounds like png support wasn't compiled as part of php or your version of gd doesn't support pnp.

Anon

the gd lib version is 1.6.2 or higher
i remove @ but no error message.....

Are you throwing a header like so:

header ("content-type: image/jpg");

header ("content-type: image/png");
