Internal.ImageData.Image
Data Model representing Image data, that can be used to create image, or convert primitives to use image pixels as data
decode : Bytes -> Maybe Image
Convert blob of image (png
or bmp
) into Image
import Http
type Msg
= GotImage (Result Http.Error (Maybe Image))
getImage : Cmd Msg
getImage =
Http.get
{ url = "/image.png"
, expect = Http.expectBytes GotImage Image.decode
}
toPng : Image -> Bytes
Portable Network Graphics (PNG) is a raster-graphics file-format that supports lossless data compression. PNG was developed as an improved, non-patented replacement for Graphics Interchange Format (GIF).
PNG supports palette-based images (with palettes of 24-bit RGB or 32-bit RGBA colors), grayscale images (with or without alpha channel for transparency), and full-color non-palette-based RGB images (with or without alpha channel).
toBmp : Image -> Bytes
The BMP file format, also known as bitmap image file or device independent bitmap (DIB) file format or simply a bitmap, is a raster graphics image file format used to store bitmap digital images, independently of the display device (such as a graphics adapter), especially on Microsoft Windows and OS/2 operating systems.
Note: Using BMP 32bit is discouraged due to lack of proper support across browsers, so image will be 24bit (no alpha channel)
toGif : Image -> Bytes
The Graphics Interchange Format (GIF)
Palette based image with support of animation (not implemented), Transparency (totally transparent color - use 0x00)
toPngUrl : Image -> String
Create base64-url that can be used directly as img source (img [ src <| toPngUrl myImage ]
)
toBmpUrl : Image -> String
Create base64-url that can be used directly as img source (img [ src <| toBmpUrl myImage ]
)
toGifUrl : Image -> String
Create base64-url that can be used directly as img source (img [ src <| toGifUrl myImage ]
)
