[Snippet] Text2PNG

I got on the bandwagon and put together a snippet to convert text to a translucent .png image. Has lots of options:

// &width - width of text image in pixels, default 100px
// &height - height of text image in pixels, default 100px
// &font - name of font
// &size - size of font, default 20
// &color - color of text, comma-separated RGB values (0,0,0 to 255,255,255) default 0,0,0
// &trans - color of transparency, comma-separated RGB values (0,0,0 to 255,255,255) default 255,255,255
// $angle - slant of text from ltr, default 0
// $left - pixels from left edge of image, default 0
// $top - pixels from top of image to baseline, default $size

The snippet generates a set of <object> tags rather than <img> tags. Dunno why, except that I just got finished reading the W3C specs on it. So just put the snippet tags where you would normally put <img> tags.

It expects the .ttf font file to be in the assets/files/fonts folder.

Thanks to Adrianus Warmenhoven for the gtext snippet’s file saving function, and to a bunch of posters to the php documentation comments.

Cool!

That’s pretty nice Susan, it seems a bit similar to SiFR, does it not ?

Anyway, I very much like all those parameter, pretty granular control over the result... that’s cool ! I’ll try this as soon as I get a little time....

sIFR requires the use of Flash/JS and can "flash" unreplaced content on a page. This creates an image headline.

I just looked at sIFR, and it uses Javascript to replace text with a .swf flash image. You have to have Adobe Flash ($699) to make the .swf flash image, then store it in the filesystem. This snippet actually generates the image on-the-fly, or uses an existing image if you’ve already created it.

Does this cache already generated files I’d assume?

Yes. That’s where the "existing image if you’ve already created it" comes from; sorry if I worded that badly.

Hello to all,

i have some strange problems with this snippet. it works half :

- the image is created, but i can’t specify the position of the text (left, top)

here is an image:



my settings of the snippet are:

$width = isset($width)?$width:425;
$height = isset($height)?$height:50;
$font = isset($font)?$font:"gara.ttf";
$text = isset($text)?$text:"Testing";
$trans = isset($trans)?$trans:"255,255,255";
$color = isset($color)?$color:"88,89,91";
$size = isset($size)?$size:27;
$angle = isset($angle)?$angle:0;
$left = isset($left)?$left:0;
$top = isset($top)?$top:$size;

if i change the value of the params "$left", nothing happens...

maybe somebody can help?

thanks!!

Hey that’s cool.
But I’m just in with sIFR...and sWFIR

advantages
- accessible (I hop so)
- no flash requiered
- no flash studio requiered
disadvantages
- not any font (or am I wrong)
- server heavy

Puh, solved!!

the parameters, $left, $top took no influence, because they were not integrated in the function call "ImageTTFText".

so this works:
