Looks like that did the trick! Thanks a ton!

Just updated from 6. We use this method of applying masks to images. convert blank.png img.png mask.png -composite img.png In 6 this worked great, in 7 the mask doesn't seem to be applied at all and the png also loses all transparency. Is there a command that I need to add in 7 to get the default be...

How do I do this in command line rose: rose-over.png Then use rose in my convert. It is not clear what you want. To use the rose: image, just use it. You do not have to rename it first. convert rose: ...some commands... rose_processed.png If you want to make a copy of the rose: image, you can do it...

If anyone has any direction I would appreciate it.

I do have one other, much simpler question. In the command line. How do I set an image to a name. for example...

What does +swap do? ImageMagick can work with stacks of images, not just single images. In that command I brought the input image in first, then I built the 400x400 white canvas second. That's their order in the stack. The "+swap" trades places of the last two images in the stack (or the ...

Having tested this, the faster method is:

Geemack, Thank you. I already have a splice example working, and I will try the other to see if its faster.

What does +swap do?

Also, if I want the xc to be none instead of white, will that work?

You can use "-splice" to add a row of a particular width to just one side of an image. Something like... convert image.jpg -background white -gravity northwest -splice 20x0 result.jpg ... would add a 20 pixel wide white row to the left side of the image. By setting "-background"...

I want to do this, but extend a side of an image. I do not know if I can use crop and just give it negative numbers.

Is there a command for this?

Okay, new question. Say I want to do 250 of these in a batch. Is there anyway to send them off to a server to have it done? I know about dev/null & I was using that for a ton of images being compiled into one. However, I am unaware if there is a method for me to build the commands and build a bu...

snibgo wrote:"-composite" needs two images before it.

"-crop" needs a geometry argument, eg 10x10+0+0.

Thank you, I meant to use Trim in this case. That should fix one issue. I will test and get back to you in a few moments.

I believe I have found the problem with all the calculations I was doing. Thank you all very much for your support.

Okay, I have everything working, but now it is not quite turning out right. exec('mogrify -crop ' . $return_var[0] . 'x' . $return_var[1] . '+' . $return_var[2] . '+'. $return_var[3] . ' +repage -resize ' . ICON_SIZE . 'x' . ICON_SIZE . ' ' . $row[0] . '.png'); I need it to crop the image and then r...
