Image Loaders

There are two methods for placing points on a map: 1) Using Markers; 2) Using SymbolLayer.

Advantages
- This method is flexible; any element that can be rendered on a web page can be used for placing points.
Disadvantages
- Creates DOM elements. When there are a large number of points, this consumes a significant amount of memory, leading to page lag.
- Does not support point clustering or expansion effects.

Advantages
- Does not require creating DOM elements, making it suitable for use with a large number of points.
- Supports clustering and expansion effects
Disadvantages
- Requires using an image loader when using icons, which is slightly cumbersome

All image loaders are designed for use with SymbolLayer for placing points. This component library provides the following loaders

ImageLoader，Static image loader, can be used to load formats such as PNG, JPG, and SVG
ImageGifLoader，Used to load GIF animations, implemented using the omggif library
ImageLottieLoader，Used to load Lottie animations; requires the application to use the lottie-web library
ImageApngLoader，Used to load APNG animations, implemented using the apng-js library
ImageFrameLoader，Used to load frame animations
VideoMp4Loader，Used to load H.264 encoded MP4 videos, implemented using the mp4box library (this loader has several limitations; please use with caution)
