I have tried different settings for hours but can't find out how to do this.

Is there someone who sees what i'm doing wrong?

Thanks a lot in advance

try this in IM 6 (replace convert with magick in IM 7)
Please always provide your IM version and platform when asking questions on this forum.

I'll try that thanks! I saw hardlight earlier today, but didn't think that was needed since the overlay is an png with transparency.

I'll check the IM version, this was done in an rails app using IM, but I'm not sure which version was used.



Thanks a lot!

Is there a question to this last image?

Haha forgot to add the question.

I haven't been able to try the code yet.

With the code you provided, will the pattern be placed between the bottom and overlay images?

The idea is that the white area of the overlay-image should cover the pattern if it's larger then the phone.

Thanks a lot for all your help!

In the code I presented, the overlay it combined with the base image using -compose hard light. Then the pattern is placed on top using -compose over. The result looks the same as your desired result except that your result is a smaller an cropped image. All your images were the same 1000x1000 size.

Perhaps if you provide your rails code, some one might be able to figure out what the equivalent command line code is.

I'm so sorry, but I saw now that I used wrong images when I created the thread.

I would like the result to be as I have it in photoshop:


This image is used as bottom:


As pattern it should be possible to use an centered image like this:


And the top should be an image like this (to keep the camera and cover the the pattern that is outside the phone)


In photoshop/gimp what I do is center the pattern between the top and bottom layers and then merge the images.

Is it possible to do similar with IM? If so how should the code be?

Thanks in advance

This is how I would use the images provided to achieve what you want.
You need to extract the alpha channel from the top.png image and negate (invert) its color. Then use that as a mask to control the overlay of the patten.png image onto the bottom.jpg image.

You still have not answered my request that you always provide your IM version and platform!
