APIs

React component

const InkAsciifyImage: React.FC<{
    url:⁰ string;
    width:¹ number;
    height:² number;
    tryCorrectAspectRatio?:³ boolean;
    renderInTwoBit?:⁴ boolean;
    alt?:⁵ string;
}>;

• ⁰ url: URL of the rendered image, supports loading local URL, or network URL based on HTTP, supported image formats include "jpeg", "png" and "bmp".
• ¹ width: Width of the rendered image.
• ² height: Height of the rendered image.
• ³ tryCorrectAspectRatio: Specifies whether to attempt to correct the aspect ratio of the rendered image, it often takes two ASCII characters to render a square like pixel point, this option would not eliminate the destructive effect on the original image's aspect ratio caused by the given width and height.
• ⁴ renderInTwoBit: Specifies whether to render the image in monochrome.
• ⁵ alt: Description of the image content, which will be displayed instead of an error message if the image fails to load.
