ctxfillRect10

ctxfillRect10 is not a standard API in the HTML5 Canvas specification. Rather, it is a name that may appear in tutorials, examples, or project code as a wrapper around the CanvasRenderingContext2D.fillRect method. In such contexts, ctxfillRect10 typically refers to a small helper function designed to draw a fixed-size rectangle, often 10 by 10 pixels, at a fixed offset, commonly at coordinates like (10, 10). The exact behavior depends on how the function is defined in the source code.

Core concept: fillRect is a method of the canvas 2D rendering context that draws a filled rectangle using the current fillStyle. A wrapper such as ctxfillRect10 is simply a convenience function that calls fillRect with predetermined arguments. Because it is not part of the standard API, its parameters, coordinates, and dimensions can vary between codebases.

Usage considerations: When encountering ctxfillRect10, check the function’s definition to understand what rectangle it draws and where. Ensure the current fillStyle is set to the desired color and that any transformation state (such as translate, scale, or rotate) is accounted for, since these affect where and how the rectangle appears on the canvas. The function itself does not modify the current path or the clipping region; it performs an immediate fill operation.

Example concept: A typical implementation might be function ctxfillRect10(ctx) { ctx.fillRect(10, 10, 10, 10); } This would render a 10×10 pixel square at position (10, 10) using the current fillStyle.
