Pb with PHP/MAMP

[Christian Roy-3]

Hi,

I am developing a hieroglyph editor (Mac SnowLeopard) and encountered  
a pb after migration to MAMP (freetype 2.3.9) environment.

My pb is that imagettfbbox does not return same values than before  
migration for hieroglyphic characters coming from a home made ttf font.

As an example, looking at the vertical dimension :  height is OK but  
returned bottom and height are different (13 and -54 before, -1 and  
-67 after migration).

Any clue will be more than welcome.

Hi,

Yet I have no intel Mac, so I cannot try to reproduce
the trouble you got - and I'm really unfamiliar with
PHP and MAMP...

Sounds interesting! Which script you're working for?

I'm not sure if you're asking about freetype specific issue,
or the incompatibility between raw PHP versus MAMP package.
Please describe what you used before MAMP (and got expected
result).

Hmm. imagettfbbox is a part of PHP - so, you find the
incompatible values between that in raw PHP (built by
yourself, or by Apple) versus that in MAMP?
If possible, could you check whether the version of
freetype is changed before/after the migration?

Please upload any TTF to reproduce the problem somewhere.
However, freetype developer will check the metric returned
by freetype is same with your expect /or not, but may not
check the metric returned by PHP/MAMP. In fact, I have no
access to Snow Leopard machine yet, and the report by other
machines, other binaries (e.g. PHP running on GNU/Linux)
would not what you want.

I am not sure to understand your question. Currently hieros are nor recognised by Unicode standard so we use code points arbitrarily chosen event not in private plane.

For further detail you may refer to http://projetrosette.info switching to english (look at top right).

Is it the answer to your question ?

I was using MacOSX Leopard. PHP provided by Appel not including freetype I rebuilt GD library including freetype 2.3.5 (http://download.savannah.gnu.org/releases/freetype/freetype-2.3.5.tar.gz)

For a given test hiero, imagettfbbox was returning for top -54 and +13 for bottom. 

My pb is that imagettfbbox does not return same values than before  

migration for hieroglyphic characters coming from a home made ttf font.

freetype is changed before/after the migration?

With MAMP free type version is 2..9 and image ttfbbox for the same test hiero than above returns -67 (top) and -1 (bottom). Height is the same but the glyph is shift to the bottom.

As an example, looking at the vertical dimension :  height is OK but  

returned bottom and height are different (13 and -54 before, -1 and  

-67 after migration).

Please upload any TTF to reproduce the problem somewhere.

A ttf file with a single hiero (Unicode point U+0000) is at 

Corresponding rendered glyph is at http://test.projetrosette.info/temp.png

However, freetype developer will check the metric returned
by freetype is same with your expect /or not, but may not
check the metric returned by PHP/MAMP. In fact, I have no
access to Snow Leopard machine yet, and the report by other
machines, other binaries (e.g. PHP running on GNU/Linux)
would not what you want.

I understanf this point.
