Make sure to check the encoder's documentation to confirm the expected data format. In other cases, you will have to provide raw byte data. Some libraries use a default image class (for example, the Swift implementation uses UIImage). Once you have the encoder, you will need to obtain a representation of the image. The key step is to locate an encoder for your chosen language, which can often be found in the woltapp/blurhash repository. The process of generating a blurhash can be accomplished in various languages and server technologies, similar to the one using JavaScript. A value of 9 will give the best results but may take longer to generate the hash. However, they must be within the range of 1 to 9 and have an aspect ratio similar to the uploaded image. These values can be calculated or hard-coded on the server or specified by the user. height, componentX, componentY ) Īdditionally, the request can include two parameters: componentX and componentY, are passed through the algorithm. Placeholder= ) const blurhash = encode (data, info. 'scale-down' - The image is sized as if none or contain were specified, whichever would result in a smaller concrete image size.Ī string used to generate the image placeholder. When specified, the exact position can be controlled with contentPosition prop. 'none' - The image is not resized and is centered by default. If necessary, the image will be stretched or squished to fit. 'fill' - The image is sized to entirely fill the container box. 'contain' - The image is scaled down or up to maintain its aspect ratio while fitting within the container box. If the image's aspect ratio does not match the aspect ratio of its box, then the object will be clipped to fit.

'cover' - The image is sized to maintain its aspect ratio while filling the container box. In a variety of ways such as "preserve that aspect ratio" or "stretch up and take up as much space as possible". This property tells the image to fill the container Default: 'cover'ĭetermines how the image should be resized to fit its container.
