Recipe for creating Windows ICO files with ImageMagick?

I would like to create .ico icon for my Windows application dynamically (from the SVG file) by using ImageMagick. How do I do that?

Microsoft lists various color depth and size requirements for the icon. ImageMagick has the -depth and -colors options, but I'm not sure how to use them correctly in this case.

Additionaly, it looks like Vista+ supports 256x256 hi-res icon embedded into the very same .ico which can (should? must?) be a compressed PNG. How do I "join" the Windows XP icons and this new Vista icon into a single .ico file?


ImageMagick has a recipe for this in their documentation, see FavIcon Web Page Link Thumbnail

Essentially you run the following:

convert image.png  -bordercolor white -border 0 \
          \( -clone 0 -resize 16x16 \) \
          \( -clone 0 -resize 32x32 \) \
          \( -clone 0 -resize 48x48 \) \
          \( -clone 0 -resize 64x64 \) \
          -delete 0 -alpha off -colors 256 favicon.ico

You can modify this to include larger resolutions as necessary and to change things like border, transparency settings etc.

Essentially you run the following: convert  Create a Windows ico file using ImageMagick. Windows 10 device metadata requires an icon file with 13 combinations of image size, alpha, bit depth, and colors. I found the open source ImageMagick 7 particularly helpful. Here’s a recipe for quickly creating an ico file, given a PNG file with enough resolution—I used one with 512x512 pixels


It doesn't seem like ImageMagick alone can do this as it does not handle SVG resizing in a sane way (but instead resizes the SVG only after rasterizing which produces a horrid result)

By using inkscape to do the conversion it appears to be possible though, e.g. The following one liner should give you a usable icon with all icon sizes:

mkdir temp; declare -a res=(16 24 32 48 64 128 256); for f in *.svg; do for r in "${res[@]}"; do inkscape -z -e temp/${f}${r}.png -w $r -h $r $f; done; resm=( "${res[@]/#/temp/$f}" ); resm=( "${resm[@]/%/.png}" ); convert "${resm[@]}" ${f%%.*}.ico; done; rm -rf temp;

The above will not however give you 8 and 4 bit icons within the file (I think these are only needed for older windows versions that are no longer supported) It should be possible with a bit more work to have it do these if you need them.

icons, ImageMagick has a recipe for this in their documentation, see FavIcon Web Page Link Thumbnail. Essentially you run the following: convert image.png  Enter a file name for the icon and type “.ico” (without quotations) as the file extension. Select your preferred output folder for the icon and click “Save.”(still in bmp type) , exposing auto definition in saving parameters window.

Essentially you run the following: convert image.png -bordercolor white  The ICO is a funny file type. It's been around almost as long as I've been alive, hasn't been updated much, but is still used widely across the web and desktop apps. So it's a bit surprising that…


I cleaned up Malcolm's solution, fixed a bug, and also made the script output tiffs so you can run tiff2icns in osx.

#! /bin/bash
# converts the passed-in svgs to tiff and ico

if [[ $# -eq 0 ]]; then
    echo "Usage: $0 svg1 [svg2 [...]]"
    exit 0
fi

temp=$(mktemp -d)
declare -a res=(16 24 32 48 64 128 256 512)
for f in $*; do
    mkdir -p $temp/$(dirname $f)
    for r in "${res[@]}"; do
        inkscape -z -e $temp/${f}${r}.png -w $r -h $r $f
    done
    resm=( "${res[@]/#/$temp/$f}" )
    resm=( "${resm[@]/%/.png}" )
    for filetype in ico tiff; do
        convert "${resm[@]}" ${f%%.*}.$filetype
    done
done

Here's a recipe for quickly creating an ico file, given a PNG file with enough  How to create ico file with more than one image. I can use imagemagic to convert png to ico but (I think, not sure) it will create one image ico file for the size I specify. And ico file can contain 2 or 3 images for 16x16 32x32 and 64x64 pixels.


Here's the standard recipe from the FAQ, modified to have all the resolutions mentioned in the msdn link (except those under "Additional sizes...") (the other answer didn't have all resolutions desired)

 convert input.png -bordercolor white -border 0 ( -clone 0 -resize 16x16 ) ( -clone 0 -resize 24x24 ) ( -clone 0 -resize 32x32 ) ( -clone 0 -resize 40x40 ) ( -clone 0 -resize 48x48 ) ( -clone 0 -resize 64x64 ) ( -clone 0 -resize 256x256 ) -delete 0 -alpha off -colors 256 output.ico

Make a multi-resolution favicon.ico from a source image, using , I would like to create .ico icon for my Windows application dynamically (from the SVG file) by using ImageMagick. How do I do that? Microsoft  For instance, I am making a button in my application, and I would like my custom made 15*32 icon from my .ico file to be displayed on the button. I know this is possible by adding the bitmaps one at a time to the resource DLL, giving each of them a unique name.


Batch convert SVG images to desired size PNG or ICO, Especially in this case where ImageMagick is poor solution for SVG conversion. Better try you create a convert.bat file with this line inside: FOR %%A IN (*.svg) Use Windows Explorer to search for the converted PNG files. On my PC ico; done; rm -rf temp; If your first file name is in B2, the above formula is accurate. The big question is how to create this file. There are tools out there to do this, but if you're interested in creating one yourself and already have (or can create) the images as PNG files, you can do it at no cost. Install ImageMagick. The first thing you need to do is install ImageMagick.


Create a Favicon Using PNG Images, Using the free ImageMagick utility, you can create multi-resolution favicon.ico files with From the OS X Terminal or Windows Command Prompt, run the command Now to convert multiple .png files into a single .ico file, just follow this format  >>I want to know if it's possible for me to use VB.NET to create Windows icons that support more than 16 colors without resorting to a third-party tool outside itself. I think this issue has no relationship with the language but the API used. As far as I know, Microsoft provides the Icon.FromHandle Method to create an Icon. If this does not match your requirement, you need to find other third party API to cover this.


= USAGE: To install just ImageMagick, include_recipe "imagemagick" In your own recipe/cookbook. To install the RubyGem rmagick, include_recipe "imagemagick::rmagick" Which will install imagemagick, as well as the development libraries for imagemagick (so rmagick can be built).
