using the imagetfftext() function

dsaba · March 28, 2007

I have problems using this function and get it to display the characters correctly

here is the text requirement taken from php.net

text

The text string.

May include decimal numeric character references (of the form: €) to access characters in a font beyond position 127. The hexadecimal format (like ©) is supported as of PHP 5.2.0. Strings in UTF-8 encoding can be passed directly.

Named entities, such as ©, are not supported. Consider using html_entity_decode() to decode these named entities into UTF-8 strings (html_entity_decode() supports this as of PHP 5.0.0).

If a character is used in the string which is not supported by the font, a hollow rectangle will replace the character.

I am using font davidtr.ttf

here are some pics from the character map from windows xp:

--------------------------------------------------------------------

as you can see from the pics its I now understand that the font davidtr.ttf supports

1. unicode (utf-

2. Hebrew (DOS) aka: DOS-862

3. Hebrew (windows) aka: windows- 1255

so according to the php manual if I try to pass any character in any of the fonts supported charsets, then it should write it with the font just fine

if not:

"If a character is used in the string which is not supported by the font, a hollow rectangle will replace the character. "

so I ran many different tests to to test this fact that the font should be able to correctly display characters in any of those above supported charsets

in order to run the test I need to successfully change a string's charset in the php script

I set this with both of these things:

1. I set this html tag <meta http-equiv="Content-Type" content="text/html; charset=windows-1255" />

2. I SAVE the .PHP file in dreamweaver in the charset, look at the picture below

-----------------------------------------------------------------------------------------

Additionally there is a handy function called mb_check_encoding(); , however it only works in php 5 or in php 4.4.3 which has the extra mb library installed, and I have neither of these, however I tried it on a friends server who does have php 5 and the encodings did check out, in the code snippets I provide below i have commented out the mb() function but if you have the library installed you're welcome to uncomment it and use it

The last two (iso logical, and iso visual) aren't supported in the character map, but I tried them anyways since they are another type of hebrew charset.

As you can see by the tests only one test worked, and the rest failed (meaning the hebrew showed up as blank white rectangles)

ONLY UTF-8 charset worked, even though according to the PHP manual and the character map for the font, which i provided references, windows-1255 and dos-862 SHOULD HAVE ALSO WORKED

as you can tell by my lengthy description and all my efforts for everyone to understand what exactly is my problem and what is my viewpoint....... that I am quite serious in my efforts to solve this problem

My question is how do I write with the font using the windows-1255 and dos-862 charsets????

-thanks for reading, and thanks for trying
