Placeholder images straight from an address, no design tools needed. Choose the size, background color, text color and caption, and receive the image ready to drop into a page or app.
Useful for wireframes and mockups, empty states and image fallbacks in production interfaces, seeding demo environments, and templates awaiting final artwork.
The Generate Placeholder Image endpoint returns a base64-encoded string representing the generated placeholder image. This image can be in scalable vector format or raster format, depending on the request parameters.
Users can customize their requests using parameters for width, height, background color, text color, and caption. Each parameter allows for specific values to define the appearance of the placeholder image.
The response data consists of a single field containing the base64-encoded image string. This string can be directly used in an image tag to display the generated placeholder image.
Typical use cases include creating mockups for web and mobile applications, designing wireframes, providing empty states in user interfaces, and generating demo content for presentations or templates.
Users can customize their requests by specifying the desired width, height, background color (in hex format), text color (also in hex format), and a caption of up to 120 characters, all in a single API call.
The accepted parameter values for colors are hexadecimal color codes, such as "#FFFFFF" for white or "#000000" for black. Users can specify any valid hex code to customize the background and text colors.
用户可以通过将返回的base64编码图像字符串直接嵌入HTML图像标签作为src属性来利用它，在Web应用程序中即时显示占位符图像
用户可以期待一致的输出模式，其中图像尺寸和颜色与指定参数匹配 文字将居中并清晰呈现 确保在样机和原型中具有专业外观
