[plugin] [ORPHAN] zem_image_replace, version 2

Kaiser · 2004-08-13 22:28:22

This is going to sound dumb, but did you activate the plugin?

I had the same problem, tried a bunch of stuff, and then realized I forgot to activate it. Sometimes it is the littlest thing.

Yes, I did.
But it was a good suggestion :)
I think we’ve all been known to miss such obvious things when looking too deeply.

Thanks, but it must be something else.

I downloaded the plugin. Installed it. Activated it.
Made a folder called “fonts” in my public_html folder on my server.
I uploaded a font named Bradley___.TTF into the fonts folder.
I changed my code in my article form around the <code><txp:title /></code> tag as shown above.
Then I tried many adjustments and variations on the setup and code, to no avail.

I hope someone can help me out here.

That’s a great idea, thanks a lot Zem.

I have a newbie question: is the GD2/ImageMagick tool is used for each new visitor on the page (each new parsing of the TXP page/article), or is it cached somehow ?

Another question: is it possible to create a default transparent (8bit, no alpha) background ? With an attribute to create alpha transparency (for the hardworker using MS filter to force IE to handle png alpha transparency) ?

> If I leave the tag as given in the plugin text, if I use corinne’s revision as shown here, if I put in fontdir=”/” or fontdir=“http://mydomainname.com/”, with or without forward-slashes all over the place, making a “fonts” folder in the root directory, in the public_html directory, in the textpattern directory – nothing seems to work! I either get a blank page or I get the aforementioned error.

“fontdir” is used to specify the local server directory name, which can be quite different to the path you see in URLs.

Take a look at your doc_root setting in the Textpattern config. It will typically (though not always) look like this:

$txpcfg['doc_root'] = '/home/example/public_html';

By default, the plugin assumes the font will be in /home/example/ – your home directory, outside the publically-accessible doc_root. This is so you can safely use a commercial font without risk of someone downloading it.

If you’re using a setting like font="fonts/foo.ttf" (without a fontdir), the plugin looks for it in /home/example/fonts/foo.ttf.

If you’ve placed the font in public_html/fonts, you’ll need to use font="public_html/fonts/foo.ttf". Or alternatively, fontdir="public_html/fonts" font="foo.ttf".

For most users on a shared vhost plan, the simplest thing to do is:

1. Upload the font file to your home directory – not public_html, but the directory that contains public_html. This will usually be the directory you start in when you use FTP.

2. Use a tag like this:

<txp:zem_image_replace font="myfont.ttf" position="right"><txp:page_title /></txp:zem_image_replace>

Welcome.

It’s cached. The plugin generates it for the first page view only, and stores it in images/zir/.

I’m not quite sure what you’re asking. The current version always creates a transparent PNG. Next release will make that optional. Is that what you mean?

Zem,
Thanks for the explanation, that is one of the many things that I have tried, but that setup gives me a blank page. Not even just my page with the font missing error, but NOTHING on the page whatsoever.

Thanks with your help on this, I would REALLY like to figure this out.

zem · 2004-08-14 00:55:25

Starz,

A blank page usually indicates a syntax error of some kind – either an error in the plugin, or possibly some broken syntax in your <txp:...> tags (unclosed tags, missing quotes, etc). Without more information, my guess is as good as yours.

You could try editing publish.php and uncommenting the ERROR_REPORTING and ini_set lines near the top – that should at least let you see an error message.

If you can reproduce the blank page issue with a particular tag, please post an exact copy of the tag so I can find the cause and fix it.

It might also help if you posted:

- your doc_root setting
- the absolute path of your font file

You can send those to me via email if you’d prefer.

Great.

I saw in your first post ??Background color, in #rrggbb format. Default is

I’m guessing that it only supports .ttf fonts. Is there any possibility that .pfm or .otf fonts will be added or is it a limitation threw PHP that stops these lovely font formats?

I had no problems with opentype .otf fonts.

But yes, only position=“right” works, and I don’t know how to use another image replacement trick that changes <span> tag with the image. <del>Example (static image) on my website as the header.</del>

css code for this technique:
<code>
.replace {position: relative; margin-left: 0.8em; padding: 0;
/* hide overflow: hidden from IE5/Mac */
/* \*/
overflow: hidden;
/* */
}
</code>
.replace span {display: block; position: absolute; top: 0; left: 0; z-index: 1; /* for Opera 5 and 6 */ }

#yourid, #yourid span {width: ...px; height: ...px; background-image: url(/path/to/image.gif);}

html example:
<h1 class="replace" id="yourid"><txp:page_title /><span> </span></h1>

Chris,

You can’t do exactly that, but you can achieve something similar. Try putting the CSS in your stylesheet, and using code like this:

It won’t supply the width and height attributes, so it may not work.

Version 0.3 is available for download. Full docs here.

New in this version:

Freetype support (which may or may not mean Opentype support)
anti-aliasing (requires Freetype)
“angle” attribute, for arbitrary text rotation
“info” attribute which might help debugging
“depth” attribute, with 8/24 bit support
“trans” attribute to select image transparency
more explicit error messages

Knock yourselves out. If the “angle” thing doesn’t start a new fad, I’ll be bitterly disappointed.

Those who are having trouble with permissions or font files should try something like this:

<txp:zem_image_replace font=“myfont.ttf” info=1>test</txp:zem_image_replace>

..to see some useful information about paths and permissions.
