decodeIco(source: ArrayBuffer | Buffer) => Image[]
Decodes the .ico
file in the given buffer, and returns an array of images.
Each image has the following properties:
width: Number
- The width of the image, in pixelsheight: Number
- The height of the image, in pixelstype: String
- The type of image, will be one of bmp
or png
bpp: Number
- The color depth of the image as the number of bits used per pixeldata: Uint8Array
- The data of the image, format depends on type
, see belowhotspot: null | Hotspot
- If the image is a cursor (.cur
), this is the hotspotThe format of the data
parameter depends on the type of image. When the image is of type bmp
, the data
array will hold raw pixel data in the RGBA order, with integer values between 0 and 255 (included). When the type is png
, the array will be png data.
The hotspot
property will either be null
, or an object with an x
and y
property.
💡 The png
data can be written to a file with the .png
extension directly, or be decoded by node-lodepng which will give you the same raw format as the bmp
type.
