Legacy ImageMagick Discussions Archive

Hi There, I use ImageMagick to create PSD files with images in multiple layers, open Photoshop, edit those PSD files (essentially align various layers) save it, and then extract and flatten the PSD file into a JPG. This works well in v6.9.0, but in v6.9.2 there's a bug. Usually the toplayer in my PS...

This is a 1-processor LAMP server running ImageMagick 6.5.4-7 2014-02-10 Q16. I've seen advice elsewhere on this forum to process large images with stream but that does not support -scale. Can I reduce image pixel count with stream? Is stream useful? Thanks! Make sure you have plenty of memory avai...

On a site I have when a new user visits the page some php code runs and deletes any files over a certain age in the temp directory. The temp file names all start with the date they were created and php checks this against the current time so as not to delete a file that is being used! That just mak...

Can you add a link to a psd file that contains a locked layer? I've created another 2 psd files linked here: https://www.dropbox.com/s/hiwn68wcndpc68w/Layer%20locking%20in%20PSD.zip?dl=0 Both psd files are identical except that in one psd file both layers are unlocked, and in the other layer2 is lo...

I'm no Photoshop expert either, but I do have access to it at work. In Photoshop (and I assume this would be true for any app that can open a PSD file), the topmost layer is the highest layer number. Ie, layer 1 is generally the background and in a 3 layer PSD, layer 3 would be the toplayer. Unfortu...

Yeah, thats my other post I was referring to.

Unfortunately this doesn't quite work. With a 3 layer PSD, it places the image in.jpg onto to topmost layer, instead of the layer I want. I tried using in.psd[1] and even specify the layer name with -label, but none of that worked. Even if I got it to work as intended, the purpose of this was to lea...

First 2 layers are locked (labelled 'guidelines' and 'cropmarks'), background layer (labelled 'Image') is unlocked.

That would be awesome!

I'll have a play with that and see what the impact is.

So does Photoshop compress (does it use zip?) layers? The difference is significant; if I create a PSD with IM from 2 PNGs and one JPG where the PNGs are basically 3 color images (white, red and transparent) and the JPG is a photo, I end up with a PSD size of 140MB or so. If I create a PSD of just t...

Sweet, I'll give that a try tomorrow. Thanks!

Hi Guys,

Is there a way to insert an image into a layer in an existing PSD file with IM? Ie, I have a PSD file with 3 layers, and want to insert a jpg into the last layer, without touching the other layers?

Cheers!

When I create a PSD file with IM with the following command: convert ( -label "top" image1.png -background none -mosaic ) ( -label "middle" image2.png -background none -mosaic ) ( -label "background" image3.jpg -mosaic ) ( -clone 0--1 -mosaic ) -reverse "output.psd...

Hi Guys, In Photoshop, one can lock layers to prevent them from being edited. I know how to create a psd file with IM as follows: convert ( -label "top" image1.png -background none -mosaic ) ( -label "middle" image2.png -background none -mosaic ) ( -label "background" i...
