Wenyan Zhang (Shanghai Wicresoft Co,.Ltd.) 36,436 Reputation points Microsoft External Staff2024-11-18T06:12:04.3966667+00:00 Canvas only provides drawing methods. After the canvas is created, the colors in it are all controlled by the developer. Therefore, canvas does not provide relevant APIs to obtain the color of a certain coordinate.
For further investigation, could you please provide the following information?
- The Maui version and platform API level. - Is your expected behavior that after drawing on the Canvas, you need some way to get the color within a certain coordinate? If not, could you please provide the specific expected behavior?
Your prompt reply will be highly appreciated.
