To convert a PNG file to an ICO file, you can use ffmpeg by running this command (replacing img with the name of your input and output file): ffmpeg -i img.png img.ico. ffmpeg does not come pre-installed on most machines however and must be installed manually.
1. To create an ICO file from a SVG while keeping aspect ratio: look for SVG proportions (eg. 1920x1080) for a max 256px wide icon, do the proportion: [1920:1080=256:x] -> x= (1080*256)/1920=144. finally, use ImageMagick convert command:
This will create an entry in the context menu of PNG files called "Convert to ICO". When you right-click file.png and select this command, file.png.ico will be generated in the same folder. InstallConvertToIcoCtxMenu.reg. (remember to replace the ImageMagick path with the path where it is installed on your computer)
The only issue is the resulting .ico file is very low quality: ico vs png (.ico left, .png right) Is there any way to edit this script and make the resulting file higher quality? This is part of a script deployed through Intune so it doesn't have the ability to touch on prem resources, otherwise I would simply create the .icos and host them there.
Add the icon to your forms. Right click your project file in the Solution Explorer and choose Properties. (You'll also find it in the Visual Studio Menu Debug -> "Your Project Name" Properties...) Choose the Application section. Under Resources - Icon and manifest browse to and select the icon file you just created.
I believe the ICO format supports more resolutions in one file, but a BMP seems to constitute a minimal ICO file. You should be able to generate BMP files easily with gd or ImageMagick. Share
Click on the picture section on the left, then click the ICO button. In the resulting Window, click 'Output Settings', if you want your icons to look perfect in Windows 10, select 256 X 256. Drag and drop your png files into the list, click OK. In the main window, click Start. Seconds later all your pngs will be converted to perfect icon files.
I want to convert .PNG files to .ICO files. I want to do it locally with out any internet dependency (so I can't use online tools like converttoico.com etc). I found a wonderful tool called png2ico, but it has a restriction that it can only convert images of size 1X1 to 256X256.
However, after converting the image, the color of the image changes. Here is my code. Bitmap theBitmap = new Bitmap(theImage, new Size(width, height)); IntPtr Hicon = theBitmap.GetHicon();// Get an Hicon for myBitmap. Icon newIcon = Icon.FromHandle(Hicon);// Create a new icon from the handle. FileStream fs = new FileStream(@"c:\Icon ...
ImageMagick (Windows/Mac/Linux) contains a command-line tool called convert that can be used for many things, including packing multiple images in one icon: magick convert 16.png 32.png 48.png 128.png 256.png -colors 256 icon.ico. The previous command takes 5 PNG images, and combines them into a single .ico file.
