How to align echarts map textures

This article provides guidance on aligning textures on echarts maps. The main issue addressed is ensuring that textures are properly aligned with the map features. Two alignment techniques are discussed: manual alignment and automatic alignment using

How to align texture on echarts maps?

1. Add the texture as an image object: Load the texture image as a fabric.Image object.fabric.Image object.
2. Position the texture image: Use the fabric.Image.set({ left: x, top: y }) method to set the texture's position on the canvas.
3. Align the texture with the map: Use the fabric.Image.setAngle(angle) method to rotate the texture to align with the map.

What are the techniques for aligning textures on echarts maps?

There are two common techniques for aligning textures on echarts maps:

1. Manual alignment: Manually adjust the texture's position and rotation using the methods described in the previous answer. This approach requires careful adjustment and can be time-consuming.
2. Automatic alignment using bounding boxes: Use the fabric.Image.getScaledBoundingRect()

Position the texture image:

Use the fabric.Image.set({ left: x, top: y }) method to set the texture's position on the canvas.

Align the texture with the map:

Use the fabric.Image.setAngle(angle) method to rotate the texture to align with the map.

4. Automatic alignment using bounding boxes: Use the fabric.Image.getScaledBoundingRect() method to get the bounding box of the texture. Then, align the texture to the desired position by matching its bounding box with the corresponding area on the map.

How to ensure textures are properly aligned when using echarts maps?🎜🎜To ensure proper alignment of textures when using echarts maps, consider the following best practices:🎜🎜🎜🎜Use high-quality texture images:🎜 Ensure that the texture images are high-resolution and have a consistent scale.🎜🎜🎜Position the texture precisely:🎜 Carefully position the texture using the methods described in the first answer to avoid visual distortions.🎜🎜🎜Consider perspective:🎜 When aligning textures on 3D maps, adjust the texture's perspective to match the perspective of the map.🎜🎜🎜Test on different screen sizes:🎜 Verify that the texture alignment remains consistent across different screen sizes and devices.🎜🎜
