Using Html tags within a dynamically created image

[jonsof]

Is this practicable?

[Gargouil]

not sure to understand your question..

you want to use dynamically created image in html tags ?

here's how:

<img src="your_generated_picture.php">

then in your_generated_picture.php file

create your picture then
output the image with imagejpg(...)

[jonsof]

Here is my page http://members.lycos.co.uk/jonsof/output_program/image_program/test_image.php

SO the width of each image is 600 and i want to decrease that value. IF a string is longer than that width then the rest it will be lost as it is being generated in horizontal direction.

SO i want to break the string when it reaches the edge of the image.

Is this practicable?

[Gargouil]

yes

you can do what you whan with image options...
what i suggest you is to first try to output only a simple image then next try to add features when this is working

don't try to complicate your function right now

[jonsof]

here is my code

$string = $_GET['string'];

$length=strlen($string);
$width=300;

$img_number = imagecreate($width,50);

$white = imagecolorallocate($img_number,255,255,255);

$black = imagecolorallocate($img_number,0,0,0);

$grey_shade = imagecolorallocate($img_number,204,204,204);

imagefill($img_number,0,0,$grey_shade);

header("Content-type: image/jpeg");

ImageRectangle($img_number,0,0,299,299,$black);

Imagestring($img_number,9,($width-9*$length)/2,15,$string,$black);

imagejpeg($img_number);

How can i do that?

[Gargouil]

take a look at

ImageFontWidth()

this can solve your problem

and.. you are not forced to call the width of the picture in html
this is optional

just call <img src="image.php?kjdhfh">

without size or if you like comlicated thing...

<img src="image.php?kjdhfh" height=X width="getwidth.php?string=abc">

Could i use a table within the image?

SO the string could be aligned, perfectly

like the marked area of the image

[Gargouil]

i don't think..

you will need to calcule yourself the width of your text then max width you can to to be able to contnue on next line..

this became a little bit complex

but is this just to output text ?
why don't juste write text in html ?

Decoding purposes 🙂🙂. What i mean, is that every guy outside my country Greece like you won;t have the ability to read greek text but only english. Thus, i want to pull the data from the database decoded correctly.

As you can see in my page, Some strings looks like awful, not decoded, do you know where is the fault.

And something more, i want to use my own fonts, i have installed true type 1 but nothing work correctly. 🙁🙁

[Gargouil]

not sure i will be able to help through the end ...

decoding is a little bit complex to me..

we will procede by step 🙂 i can can help to solve half .. 🙂

for your true type problem

take a look at this

http://www.php.net/manual/en/function.imagettftext.php

use thig instead of imagestring()

[jonsof]

I have already used this function and i am facing too many problems. One is that, php cannot find or open a font while it exists in the same folder as the rest of php code.
🙁🙁 i am so frustrated

[Gargouil]

i don't have any other ideas...

sorry 🙁

[jonsof]

here is the alternative piece of code

$string = "John";
$length=strlen($string);
$width=300;

$img_number = imagecreate($width,50);

$white = imagecolorallocate($img_number,255,255,255);

$blue = imagecolorallocate($img_number,0,0,255);

$black = imagecolorallocate($img_number,0,0,0);

$grey_shade = imagecolorallocate($img_number,204,204,204);

imagefill($img_number,0,0,$white);

header("Content-type: text/html; charset=iso-8859-7");

header("Content-type: image/jpeg");

ImageRectangle($img_number,0,0,299,299,$black);

imagettftext($img_number,0,4,0,2,$blue,"arial.ttf",$string);


imagejpeg($img_number);

the arial.ttf is in the same folder with the php file

i run the file through the browser but a dead pic link occurs.

Although i have installed all the component ( I used the installation kit phpdev423) ti doesn't work as i expext 🙁

I put the code accompanied by the the arial.ttf on the tripod host and it didn't work. 🙁🙁

[Gargouil]

maybe you can try a little exemple on the php.net site...

i don't know how but it's possible that tripod block you somewhere

[jonsof]

i have tried the examples in the
imagettftext() in the php.net but neither of the worked for me 🙁🙁

Does the snippet i gave you work for you?

[Gargouil]

your snippet create a box but no text inside

then i tried the php.net exemple to and he is working (with the .ftf file in the same folder ...)

  header("Content-type: image/jpeg");
  $im = imagecreate(400,30);
  $white = imagecolorallocate($im, 255,255,255);
  $black = imagecolorallocate($im, 0,0,0);

  // Replace path by your own font path
  imagettftext($im, 20, 0, 10, 20, $black, "/path/arial.ttf",
  "Testing... Omega: Ω");
  imagejpeg($im);
  imagedestroy($im);

[jonsof]

imagettftext($im, 20, 0, 10, 20, $black, "arial.ttf",
  "Testing... Omega: Ω");

I put this as the ttf is in the same folder but it didn;t work.

Should i download any other library? or anything else?

I have installed gd 2 with true type support but ...

Could true type 2 solve come up with this situation?

[Gargouil]

i don't know i don't program a lot with this feature

when pasting the sample integral that don't work ?

if not, this is a config problem.. cause it work for me

[jonsof]

Have you used any installation kit? Could you send me the php.in?

[Gargouil]

i am using easyphp kit

www.easyphp.org stable version (0.6)
