Hello!
To composite images i use: http://php.net/manual/ru/imagick.compositeimage.php

How to use that with blend mode "Linear-dodge"?

Moved to Imagick forum

sorry, misunderstood

Apparently, from http://us3.php.net/manual/en/imagick.co ... ompositeop, they did not implement linear_dodge. Imagick is not well maintained and does not have all the options in Imagemagick. You may have to use PHP exec() to do that.

This is the specific forum dedicated to Imagick

The closest I see is colordodge. You could try that. Otherwise, use PHP exec() with the command line version of the code you want to implement.

According to http://www.imagemagick.org/Usage/compose/#lineardodge, it is the same as -compose plus, except for partially transparent pixels.

Hmm... okay... but imageck haven't constant with that blend mode:
http://php.net/manual/ru/imagick.constants.php

That is why I asked a question there.
I do not understand how to write the correct command.
I tried to understand anything from the documentation, but did not understand, and therefore do nothing at random to failed:

Hmm... ok, Thank you! i'l try it!

Yes, that is correct. Imagick does NOT have that mode. So you have two choices.

1) try using COMPOSITE_PLUS
2) use PHP exec()

-define compose:args=100,0

That will choose one or the other image. So it will do nothing useful. You would have to use some mix, such as 50,50.

COMPOSITE_PLUS helped!
Thank you so much, fmw42! Or how you real name? Fred?
You saved me from sleepless nights!
Happiness and success to you!
