Bug #11976 Updated: image_copy_resized does not work properly

ID: 11976 User updated by: yannbarrault@yahoo.fr Reported By: yannbarrault@yahoo.fr Status: Feedback Bug Type: GD related Operating System: windows 98 SE PHP Version: 4.0.6 New Comment: The image result supposed to be a png image like this: ---------------------------|- | | | | | | | | | | | | | | | - | | | | | | | - | | | | | - - | | | - | | | So it is supposed to be a graph with blue rectangles and two black lines, not a black square. Previous Comments: ------------------------------------------------------------------------ [2001-07-23 11:43:58] yannbarrault@yahoo.fr My script should not draw a black image but a blue graph( blue rectangles). Actually, with php4.0.6, my script draw a black square and with php4.0.5 my script draw a graphics with blue rectangles. It works with php4.0.6 only if I don't use the function image_copy_resized. So In conclusion, I think that there is a problem with this function on php4.0.6 with W98 OS?? ------------------------------------------------------------------------ [2001-07-23 09:33:38] andy@php.net so what is the problem. The image works now... Just make sure you set the header to "image/png" or whatever file type the image is. ------------------------------------------------------------------------ [2001-07-23 06:24:34] yannbarrault@yahoo.fr When I removed the header function (or set it to "text/html"), I have this on my browser: " PNG "?? If I keept "image/png" or "image/jpeg", I have a all-in black image?? ------------------------------------------------------------------------ [2001-07-21 20:51:42] andy@php.net Works fine for me (I am using Linux.) Try removing the header function (or set it to "text/html") and see if there are any errors/warnings that are corrupting the image. ------------------------------------------------------------------------ [2001-07-09 10:04:13] yannbarrault@yahoo.fr I used this function in a script with PHP 4.0.5. It works very well. I installed PHP 4.0.6 and the script doesn't work anymore? I found that it was this function who didn't work well. Sorry about my English. See my script: <? Header("Content-type: image/png"); $x=400; $y=400; $data=array (3, 1, 7, 2, 5, 4, 6); $im = imagecreate($x,$y); $black = ImageColorAllocate($im, 0,0,0); $blue = ImageColorAllocate($im, 0,36,135); $white = ImageColorAllocate($im, 255,255,255); ImageFilledRectangle($im,0,0,$x,$y,$white); imageline($im,0,50,$x,50,$black); imageline($im,$x-50,0,$x-50,$y,$black); for($i=0;$i<sizeof($data);$i++) { ImageFilledRectangle($im,$i*50+15,51,$i*50+40,51+$data[$i]*30,$blue); } $image=imagecreate(500,500); imagecopyresized($image,$im,0,0,0,0,400,400,400,400); Imagepng($image); ?> ------------------------------------------------------------------------ Edit this bug report at http://bugs.php.net/?id=11976&edit=1
