函式: convert2WorldSpace()

convert2WorldSpace(point, viewPortWidth, viewPortHeight, cameraPosition, cameraZoomLevel, cameraRotation): Point

定義於: packages/board/src/camera/utils/coordinate-conversion.ts:102

Converts a canvas point to world space using current camera state.

參數

point

Point

Point in canvas coordinates (origin at bottom-left)

viewPortWidth

number

Viewport width in CSS pixels

viewPortHeight

number

Viewport height in CSS pixels

cameraPosition

Point

Current camera position in world coordinates

cameraZoomLevel

回傳

Point

World space coordinates of the point

備註

Input coordinates use canvas space with origin at bottom-left. This is useful when working with canvas element coordinates directly.

For points already in viewport space (origin at center), use convert2WorldSpaceAnchorAtCenter instead.

範例

// Convert bottom-left corner of canvas to world coords
const worldPos = convert2WorldSpace(
  { x: 0, y: 0 },
  1920, 1080,
  { x: 100, y: 200 },  // camera position
  1.5,                  // zoom
  0                     // rotation
);
