So you were stuck on the search criteria for this forum, this site, and PHP.net? Impressive.

I'm pretty sure there's all sorts of discussions here on resizing images. Then check out php.net and there's some image functions that allow you to place text. Check out the different functions available (since each text one has different features) and then check out the comments for those functions. The comments usually have some great code snippets in there...

i know how to isert a text in image.....

but what i dont know to insert the text in the bottom of the image but not on the picture

lets say i hace a picture the size of it is (400,300)

i want to add the text in this position(200,310)...

how can i do it......

i searched in the forum but i didn't find what i want

If you use imagestring(), then there's an x and y coordinate you can plug in:

int imagestring ( resource image, int font, int x, int y, string s, int col)

If you're using something like imagettftext(), it too has an x and a y coordinate you can specify:

array imagettftext ( resource image, int size, int angle, int x, int y, int color, string fontfile, string text)

where X = 200 and Y = 310

Although if you're max image size is only 300, and you try to place the text at 310, you won't see the text since the image size is only 300. You'll probably have to create a new image of 400x310 and then insert the desired image at 400x300, and then add text at 310 (which actually is still going to fall off the image - you'll want to do something like: Y = (font height - max image height - SomeExtraPadding)).

$imageHandler=imagecreatefromjpeg("example.jpg");
$width=imagesx($imageHandler);
$hieght=imagesy($imageHandler);
$imageHandler2 = imagecreate($width,$hieght+20);
$colorWhite = imagecolorallocate($imageHandler2 , 255,255,255);
$colorBlack = imagecolorallocate($imageHandler2 , 0,0,0);
imagecopy ( $imageHandler2, $imageHandler, 0, 0, 0, 0,$width,$hieght+20);

imagettftext($imageHandler2, 10, 0,0,$hieght+10, $colorWhite, "Font1.ttf","Ramez Sever");
imageinterlace($imageHandler2);
imagejpeg($imageHandler2,"",120);

but the picture resolution change and the picture become ugly

[AstroTeg]

I haven't played with the code, but I think

imagecopy ( $imageHandler2, $imageHandler, 0, 0, 0, 0,$width,$hieght+20); 

the $hieght+20 can be just $hieght. I think the +20 is telling PHP to stretch the image to fit your new dimensions, which isn't what you want...

[ramez_sever]

when i use this
imagecopy ( $imageHandler2, $imageHandler, 0, 0, 0, 0,$width,$hieght);

the text not appear in the image

[AstroTeg]

The produced image have the new height? If so, you may need to make sure you're not printing white text on a white background and make sure the text is making vertically in the image (maybe try setting the y position to just 10 and see if it puts your text at the top).

[ramez_sever]

thanks i used the black color for the text and ti's work fine

but still the resolution of the image is not good the color change and it's become ugly

[chriswheat]

in your code you have

$imageHandler2 = imagecreate($width,$hieght+20);

change that to

$imageHandler2 = ImageCreateTrueColor($width,$hieght+20);

then your image should be better looking.

Tutorial for adding text to image:
http://www.acecoolco.com/media_tutorialshow.php?id=43

<?php
// Import the image to use... (Uses this file as background)
$TheImage = ImageCreateFromPNG("./imagefile.png");

// Color the text...
// We use 0x before the HEX value so you can use the hex value..
// If you do not use 0x then you must give in a 0-255 value for the color.
$ColorText = imagecolorallocate($TheImage, 0xFF, 0xFF, 0xFF);

// printing the text:
// $TheImage is so it prints on that image.
// 14 is how large the font is
// 0 is the rotation (add and the right side will tip up)
// 5 is how far it is from the left side of the image
// 20 is how far it is from the top of the image
// $ColorText gives the text its color
// Verdana is the font it uses
// Some sample text is the text is prints...
ImageTTFText($TheImage, 14, 0, 5, 20, $ColorText, "Verdana", "Some sample text");

// Let the browser know that it is an image..
header("Content-Type: image/PNG");

// We want to show the image (in png format...)
ImagePng ($TheImage);
?>
