ImageMagick is widely used in industries such as web development, graphic design, and video editing, as well as in scientific research, medical imaging, and astronomy. Its versatile and customizable nature, along with its robust image processing capabilities, make it a popular choice for a wide range of image-related tasks.
ImageMagick includes a command-line interface for executing complex image processing tasks, as well as APIs for integrating its features into software applications. It is written in C and can be used on a variety of operating systems, including Linux, Windows, and macOS.
The main website for ImageMagick can be found at The most recent version available is ImageMagick 7.1.1-35. The source code for this software can be accessed through a repository. In addition, we maintain a legacy version of ImageMagick, version 6.
Creating a security policy that fits your specific local environment before making use of ImageMagick is highly advised. You can find guidance on setting up this policy. Also, it's important to verify your policy using the validation tool.
One of the key features of ImageMagick is its support for scripting and automation. This allows users to create complex image manipulation pipelines that can be run automatically, without the need for manual intervention. This can be especially useful for tasks that require the processing of large numbers of images, or for tasks that need to be performed on a regular basis.
In addition to its core image manipulation capabilities, ImageMagick also includes a number of other features, such as support for animation, color management, and image rendering. These features make it a versatile tool for a wide range of image-related tasks, including graphic design, scientific visualization, and digital art.
Overall, ImageMagick is a powerful and versatile software suite for displaying, converting, and editing image files. Its support for scripting and automation, along with its other features, make it a valuable tool for a wide range of image-related tasks.
Examples of ImageMagick Usage demonstrates how to use the software from the command line to achieve various effects. There are also several scripts available on the website called Fred's ImageMagick Scripts, which can be used to apply geometric transforms, blur and sharpen images, remove noise, and perform other operations. Additionally, there is a tool called Magick.NET that allows users to access the functionality of ImageMagick without having to install the software on their own systems. Finally, the website also includes a Cookbook with tips and examples for using ImageMagick on Windows systems.

Since Rasterize appears on the Layer menu, you can assign a custom keyboard shortcut to it if you want. IIRC, there is already a default one set (Return or Enter?) but I use the = key for that because I am less likely to tap it by mistake.
I have tried almost all ways to copy and paste on affinity photo and its copying in a way but when I paste the picture I copied for some reason it zooms in to the photo and I don't get the full photo I want?
Hi julia_mysterywhite,
Welcome to Affinity Forums
The image you are pasting in probably bigger than the canvas size so you are only seeing part of it. Change to the Move Tool, select the image clicking on it on canvas then zoom out as needed until you see the whole bounding box (the blue line with the handles). Click and drag one of the corner handles to scale it down as needed then drag it to the canvas area.
Hi MarkPM,
There's no way to create Image layers directly by the user. Image layers are considered "objects" you place in your document that can be then rasterised (if needed) for further manipulation at a pixel level as pixel layers (after you rasterise them as described above).
Image layers are created for you when you use the command File > Place (to place an image in your document), use the Place Image Tool (available in Affinity Designer and Publisher only, for the same purpose) or drag an image file from Finder (macOS) or Windows Explorer (Windows) directly to an open document in an Affinity app.
Also (which I only learned of recently), on Windows one can select a pixel layer in the Layers panel, Ctrl+C to copy it, and Edit > Paste Special > PNG will give an (Image) copy of the (Pixel) layer. I've read reports that Affinity on Mac doesn't have Paste Special, so this might be Windows-specific.
Hello, I tried your suggestion. When I open my NEF files (Nikon raw) it opens on a layer. When I rightclick on the image and I choose Rasterise, I can't see it's a Pixel layer. See enclosed image. What am I doing wrong?
Also note that ".NEF" in the name of the layer is just that -- part of the default name given to the layer. You can change to whatever you want by double-clicking on the name field. IOW, it does not indicate that the layer is a Nikon RAW file.
Hi everyone.
I have obtained some 8-bit color images by EPMA. In these pictures, different colors indicated different intensities, (there is a histogram to indicate the intensities). I want to convert these colored pictures into grayscale with intensities corrospondingly, and then combine these grayscaled images together using channel merge , and then add different colors to each channel to compare differences of their distribution and intensity. Do you have some suggestion? thank you very much.
by the way, I have already changed these colored pictures into grayscale by Edit > Options > Conversions > (checked)scale with conversion, weighted RGB conversions, Image > type > 8-bit. But the conversion results are not in accordance with intensities indicated by the histogram, especially the red spots. See details in the attached pictures.

Thank you very much for your reply in such a detailed manner (that is what i need, i am new on ImageJ ). this a good solution.
And I have found another solution, there is a macro written by @oburri, it also helps a lot.
Thanks!
Hi, imagejan,
Of course I can post the link here. But I think this has already been post in ImageJ forum by @oburri. Shall I post it here again?

I also have this issue and have had for months since I upgraded. But the replies on this are absolutely lost on me. My iPhone drops images to my iMac as HEIC. I used to just convert these to jpegs, now I can't. Need a quick and easy solution. Why is apple making everything more and more difficult these days.
I noticed this issue affects the "Create a PDF" feature as well - you can temporarily resolve it by using the "Force Quit" on the Finder app and and try again - it worked for me, however you might need to re-do it occasionally until they resolve this issue in IOS.
My User Convert Image QA handles the JPG images that Apple's Convert Image does not. Just converted the Z8 Taylor Swift image to Tiff using my own QA. EXIF data from original image comes along for the ride.
In Safari 17.2.1, when I visit the DP Review Z8 review page and select the Taylor Swift image, it makes no difference if I click the JPEG version (opens in the browser window and right-click to Download), or I right-click on the JPEG link and choose Donwload. In either case, Convert Image is silent.
So I checked the gf's 2017 21.5" non-retina iMac running Ventura. It also converts the images. However, there is a delay before the converting window shows up. So that's three different Macs running three different versions of macOS and they all convert the images using Quick Actions.
Here is a link to the above User Convert Image that when you select it, a prompt will ask you if you want to open it in the Shortcuts app. Do so, and save it. Should be zero coding involved. Then quit Shortcuts.
None of the Z8 JPG images downloaded from the DPReview site open the Convert Image Quick Action on Sonoma 14.4 for me. Makes no difference if the image is saved from Safari 17.4 or Firefox 124. But my home grown Quick Action works correctly.
For color or RGB imageIt will render a tensor of 3 channels. Each channel is an (n,n) matrix where each entry represents the respectively the level of Red, Green or Blue at the actual location inside the image.
