[RESOLVED] New problem

john1704

Now I'm getting 5 error messages about imagecopyresampled not being a valid image resource. Know why this is? Thanks once again.

<?php
Header ("Content-type: image/png"); 
$text = $_POST['text'];
$uploadedpic = $_FILES['picture']['tmp_name'];
$uploadedpicturefinale = fread(fopen($uploadedpic, "r"), filesize($uploadedpic)); 
$img_handle1 = imageCreateFromPNG("/home/john1704/public_html/sign-generators/baseball_base.png");
$font = imageloadfont("/home/john1704/public_html/sign-generators/impact.gdf");
$color = ImageColorAllocate ($img_handle1, 255, 255, 255);
$img_handle = imagecopyresampled($img_handle1, $uploadedpicturefinale, 84, 63, 84, 63, 291, 359, 400, 491);
ImageString ($img_handle, $font,  137, 27,  $text, $color); 

ImagePng ($img_handle); 

ImageDestroy ($img_handle); 
?>

Once again, $uploadpicturefinale is not an image resource - it's raw image data.

Thanks, I know what the problem is now but how do you fix it? I'm trying to create an image generator where it takes a pic you uploaded, and pastes text and your image onto an already created base image.

Use one of the imagecreatefrom___() functions on the uploaded file to create an image resource.

Alternatively, you can read the uploaded file into a string (such as by using [man]file_get_contents/man) and then use [man]imagecreatefromstring/man to create an image resource from that string of data.

[man]file_get_contents/man reads the data of a given filename into a string. I was suggesting you use that instead of the fread/fopen/filesize combination since the function basically combines all 3.

Read the manual for [man]imagecopyresampled/man and you'll see that it doesn't return a new image resource handler, but rather a boolean value.

You need to use the image resource of whichever image you're wanting in the end, which I guess to be $image_handle1.
