I want to be able to save a file of my logo, with a guassian blur filter under it, that blurs any background you choose to place it on. The text of the logo is within a rectangle and it's transparent so a blurred effect is necessary for images with lots of detail otherwise the text on the logo is hard to read.

A filter of guassian blur would be very helpful because you otherwise have to apply guassian blur on a small part of every image you place the logo on which isn't something i think the association (which is driven by volonteers) could handle.

It's not vital to the visuall identity, i could think of other ideas for external communication involving photography, or express that you must only use it on backgrounds without a lot of detail, but it would be really great if it's possible to do.

    Its possible but not practical, see it only ever works in the authoring application but you can not save it part of say a png and thus it can not do so on a web page irrespective of background. Also if you do it in illustrator it wont react with photoshop and vice versa. – joojaa Jan 11 '17 at 17:25

    Could you clarify, do you want to save an image file (as in JPG/PNG/whatever) that acts as a filter for anything underneath that image? Or are you talking about something to use specifically in Photoshop/Illustrator etc? – Cai Jan 11 '17 at 17:26

I'm sorry, but as already hinted in comments, a general type photo file such as PNG, has no way to cause its background to be blurred or other complex filtering. A photo can only hide the background on which the photo is placed. Hiding can be only partial, if the photo has some transparency. I have no way to create a PNG which makes something blurred on your document in case you embed my PNG.

Of course some theoretical possiblities exist:

  • to hide an ingenious piece of malware into my PNG
  • you have a specially programmed platform that recognizes something in my PNG and that's the signal to blur the area beneath my PNG

Both methods unfortunately are impractical, because I can't force you to use a platform which is infectable by malware or preprogrammed to do the wanted blurring.

  • The second option was done by Adobe Fireworks. They 'hid' all of the editable information in PNG metadata. It was horrible. – PieBie Jan 12 '17 at 8:25
  • Another example would be SVG with a stylesheet could do this on a webpage but again not much use elsewhere. @PieBie – joojaa Jan 12 '17 at 12:28
  • And given that there is no reason to execute a PNG in the first place, option 1 would be incredibly difficult. And even if you succeed, it only works if the loophole is fixed. – Wrzlprmft Jan 24 '17 at 8:46
