Hi!
Can anybody please help?
I try to create a primitive, like ellipse and fill it use canvas with transparent background.
But in this case all under transparent background become transparent too.
How I can blend primitive filled with canvas with transparent background and other semi-transparent entities/primitive which are located under first primitive (filled with canvas).
Example:

Thanks!
It’s not entirely clear whether this is the effect that you want to achieve, but you might be looking for
const material = new Cesium.Material({
translucent: true, // <--------------------------------- this line?!
fabric: {
...
Hi! Thank you very much for your answer!
Yes, I want to have an effect like in your example. But in your example, the black text becomes not black, looks like it blends with the semi-transparent white rectangle (but the rectangle located under the text and text, which locate upper, have to be fully black).
The same effect I have if I draw text in this way:
let material = new Cesium.ImageMaterialProperty({
image: canvas,
transparent: true
});
var eEntity = viewer.entities.add({
name: "Single Large Canvas of Labels",
rectangle: {
coordinates: Cesium.Rectangle.fromRadians(
lng + offsetX,
lat + offsetY,
lng + offsetX + 0.00001,
lat + offsetY + 0.000002,
),
height: 100 + 0.01 * i,
material: material
},
});
Is it possible to live text black color if text upper the semi-transparent white rectangle?
Only transparent and semi-transparent colors in materials canvas have to be blended with primitives/entities under it. Is it possible ?
You can see difference in text black color in next photos:
Not transparent background becomes a semitransparent too.
I need that only transparent and semitransparent canvas color will have a transparency.
Not transparent color will not have transparency. Is it possible?
Example (that non transparent colors become a transparent):
