什麼是圖片裁剪工具?

在你的瀏覽器中實現像素級精確裁剪。輸入裁剪區域的X/Y偏移量以及以像素為單位的寬度/高度:當你需要為縮圖、頭像或廣告橫幅設定精確尺寸時非常有用。

常見使用場景

  • Trim a screenshot down to a single UI panel by reading the pixel coordinates from a design tool and typing them in.

  • Produce a square avatar by setting equal W and H and centering the X/Y offset on a face.

  • Cut a fixed-size banner or ad slot (for example 728x90) from a larger source image.

  • Crop the same region from a batch of identically framed images using one set of remembered coordinates.

  • Remove an unwanted border or watermark strip by offsetting X/Y past it and shrinking W/H.

  • Extract a sprite or icon from a sprite sheet whose cell coordinates you already know.

常見問題

如果我的裁剪區域大於圖片會怎樣?
畫布(canvas)會採用你指定的尺寸,但可用的來源像素僅限於圖片的邊界範圍之內。
