Simple Image .png Question

[jmrosenwald]

Hey guys

What function would I use to portray a different image on a php parsed .png file?

I want to layer the images I guess. Is there a function like imagestring I could use to draw a image?

 

Thanks

Joe

i cannot exactly tell what you mean but to display a different file if a php file is parsed you would do this:

 

<?php

$somefile = "image1.png";

$anotherfile = "image2.gif";

if($_FILES[$somefile]['type']=="image/png") {

print '<img src=' . $otherfile . ' />';

}

else {

print '<img src=' . $somefile . ' />';

}

?>

What I want to do is display a smaller png in the png i create from this imagepng()

I can't figure out how to use that correctly.

Let me show you:

 

http://www.renaxgade.net/sigs/tictactoe.png

 

That is a board created from php. I want to display X's and O's on it (jpg's) if the right get variable is passed.

 

imagecopyresized($image, "http://renaxgade.net/sigs/x.jpg", 0, 0, 0, 0, 108, 108, 432, 432);

 

So 108x108 = size of image I want to import onto the bigger image, which is 432x432. It should place it at the top left corner.

However, I just get an error and it won't spit the image back.

 

Thanks again

What is the error message?

 

I would use imagecopymerge - you're doing the same thing as a watermark so...

imagecopymerge($image, $watermark, $dest_x, $dest_y, 0, 0, $watermark_width, $watermark_height, 100);

Try this code. It may be that the value of the source is broken somewhere so i laid it out nicely. It should create a new image called x_s.jpg in you source directory.

 

<?php
// The image sources
$dst_image = $_SERVER['DOCUMENT_ROOT'] . '/sigs/x_s.jpg';
$src_image = $_SERVER['DOCUMENT_ROOT'] . '/sigs/x.jpg';

// the destination coordinates
$dst_x = '0';
$dst_y = '0';

// the source coordinates
$src_x = '0';
$src_y = '0';

// the new image size
$dst_w = '108';
$dst_h = '108';

// the source image size
$src_w = imagesx($src_image);
$src_h = imagesy($src_image);

//the function
imagecopyresized($dst_image,$src_image,$dst_x,$dst_y,$src_x,$src_y,$dst_w,$dst_h,$src_w,$src_h );
?>
