Yes. Jpeg doesn't support transparency. Users may use my function on various image formats.
This is why I would like to change output image format. But, how to enrich my function in image transparency detection?
I think image extension or format is not enough.

[code] try { $newIm = new \Imagick(); $newIm->setBackgroundColor(new \ImagickPixel('transparent')); $newIm->readImage($file); $geo = $newIm->getImageGeometry(); $newIm->polaroidImage(new \ImagickDraw(), $value); // IM >= 6.3.2 $newIm->resizeImage($geo['width'], $geo['height'], $this->gfxConf ...

Hi!

I'm writing PHP functions with Imagick to make some effects on the webpages. I use polaroidImage function but when non transparent images are posted I see black border. I would like to have transparent background.

How can I detect if image supports transparency and then save as f.e. PNG ?

[b]@vinny38[/b] I see two problems in your installation. You are mixing quantum Q8 (ImageMagick) and Q16 (PHP Imagick). On the pecl site there are only Q16 versions.

I got an answer on my question. In the source code I found two undocumented constant Imagick::IMAGICK_EXTNUM and Imagick::IMAGICK_EXTVER.

I tried compositeImage() with no success. combine takes 4 files and does the magick. compositeImage() works on 2 files, composite constant and coordinates. I just don't know how put it all together. Could you help me a little bit more?

I'm trying to make with Imagick the same as ImageMagick command:

[code]combine -compose over input.jpg over.gif black&white_mask.gif output.jpg[/code]

The output file should consist of input & over files - depending on mask file.

How can I achieve this?

I've red on the Wiki that Unisys had rights to patent for Gif format with LZW compression. I've also read that those patents had expired.

If your site maintains photos for web viewing only then you may consider to reduce resolution. Most computer screens are able to display anything in 72 dpi. Most cameras make photos in bigger resolution (300 dpi or more). See Imagick::setImageResolution and Imagick::setResolution. Reducing ...

Hi!

I would like to know if there is any way to get Imagick version in PHP. I don't want to get ImageMagick version because I ca use Imagick::getVersion(). One more thing I can't use exec & system functions.
