Re: PNG opacity in composition

Ah, it's multiply in that way. I was thinking of blending options like those in Photoshop. Never mind, I get it now.

The text is not always black, it can be any color. Will this code also work than?

Re: PNG opacity in composition

Thanks snibgo, that seems to work! But is multiply giving the same results as normal opacity? I don't need special- or blending effects.

Re: PNG opacity in composition

Thanks snibgo. I know but that's not the problem. The image of the text is a full black box (of the image boundaries) at the opacity given with "-evaluate set 40%". The text is completely gone. Here are some input images: Image: https://dl.dropboxusercontent.com/u/3039204/imagemagick/forum...

PNG opacity in composition

I'm creating a composition of images with methods as described here: http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=23883. For each layer I create separate image first (according all selected options in app), and then I'm merging those in one image. The problem is with text imag...

Add semi-transparent inner border over source image

First, I've searched the forum and docs but I can't find a similar question to mine. I hope you all can help me. I want to add an semi-transparent surrounding inner-border of 20 pixels (for example) to a single jpg image. With -shave and -border I've created the inner border effect already, but I've...

Re: Wood tiles overlay with multiply, offset & density

Thanks fmw42! That seems to do the trick. Is it also possible to get the width & height of the loaded image source.jpg, instead of manually entering pixel sizes?

Re: Wood tiles overlay with multiply, offset & density

I just posted the input files above in the original post. The wood image should be exactly on the white lines on source.jpg.
I think I can handle the DPI problem by myself right now, but I don't think "composite" is the right command for my use.

Re: Need help with recreate canvas from multiple images + co

I think snibgo's approach gives a good result, is easy to understand, and is easy to modify as you need. -distort is capable scaling without the needing a separate -resize. It with give slightly better results slightly quicker, but it's not worth it. Or -distort SRT could have been replaced with -r...

Re: Need help with recreate canvas from multiple images + co

Thanks snibgo! It works! You said there are many approaches, I really would like to know the main differences between them and why you chose this one. I'm willing to learn and in my opinion the docs are not a good starting point for a beginner. I was struggling with -geometry and -distort, but it se...
