||
| Usage | ||
| ---------------------------------------------------------------- | ||
|
|
||
| Remember that all images that uses this plugin | ||
| must have both height and width specified. | ||
|
|
||
| 1) Add this CSS rule to "blueprint/ie.css": | ||
| img { behavior: url(*YOURDOMAIN*/css/blueprint/plugins/iepngfix/iepngfix.htc) } | ||
|
|
||
| 2) Customize the *YOURDOMAIN* and the rest of the URL in the CSS rule | ||
| to be the http path to the iepngfix.htc file. | ||
|
|
||
| 3) Customize line 15 in iepngfix.htc so that the URL is the | ||
| http path to blank.gif in this directory. | ||
|
|
||
|
|
||
| Known Issues | ||
| ---------------------------------------------------------------- | ||
|
|
||
| * Does NOT work with repeating background images | ||
| * Can't help IE versions prior to 5.5, sorry. | ||
| * Users can't right-click-save processed PNG images, they'll | ||
| save the blank GIF file if they try that. In some cases | ||
| this might be a feature, not a bug... | ||
| * The script detects the ".png" extension in image URLs. | ||
| So if you have a CGI script that generates a PNG image, you | ||
| may have to rewrite parts of the script, or just cache them | ||
| as PNG files somewhere. | ||
| * It's most reliable on elements with non-'auto' dimensions | ||
| set. So, give images and other elements width/height values; | ||
| '100%', '10em' and '200px' and so on are all OK. | ||
| * Background PNG images can't be tiled. This is a limitation | ||
| of the IE filter. | ||
| * Similarly, padding and borders don't indent the PNG image. | ||
| An easy fix for this is wrapping your PNG images in container | ||
| DIVs or similar. | ||
| * There may be about a short time as soon as the image loads | ||
| when images are not transparent, before the IE filter kicks in. | ||
