Hello Team,

Can any one please let me know how can I do the below operation for a single PNG image in Imagick / ImageMagick?

"Set blending mode as "screen" and opacity to 50%"

Note: I did that with the two different images using "compositeImage" Imagick function but in this I need two layers/Images and now I need to do the mentioned setting in single PNG or any other type Image.

Thanks in advanced.

At the command line, use "-compose Screen". In IMagick, the mode is a parameter of the compositeImage() function. See http://phpimagick.com/Imagick/compositeImage

To set opacity to anything, use "-evaluate set" at the command line, and evaluateImage() in IMagick.

Hello Snigbo,
I have used and checked both the Imagick functions.
I need to know how to Set blending mode as "screen" for a single image because the sample link is used two different images and same I already used with two images.
Please suggest if I can used "Screen" blending more with one image?

I don't know what that means. If you set a blending mode for a single image, what do you expect to happen? Do you expect that this will change the image somehow?

Not sure what will happen if applying blending mode as "screen" on single image.
I think there will be no effect on single image if applying blending mode as "screen".
