Crop

Overview

Extracts a rectangular area from an image using coordinates. Use it to take one frame from a sprite sheet, extract the needed area from a large reference image, or remove padding.

Usage tips

• A frame in a sprite sheet is determined mechanically by x = column × frame width, y = row × frame height. Turn x into a variable and iterate it with batch_render to process every frame at once. If you want to treat the input as a sprite sheet, the dedicated sprite_sheet_frame_get is easier.
• To keep the artwork unchanged and only narrow the canvas, use canvas_resize, which supports anchor-based placement such as centering. Crop uses coordinates from the top-left origin.
• Keep coordinates pixel-accurate. Zoom in on the preview boundary before finalizing it.
• The output is always exactly width × height. Areas outside the source—including a rectangle entirely beyond the source—are transparent.

Common pitfalls

• The edge is off by 1px: x/y are zero-based. The second frame starts at x = コマ幅×1.
• The selection extends beyond the image: the output size stays fixed and the overflow becomes transparent. Check x+width and y+height if transparency is unexpected.
• Transparent padding should be removed automatically: consider automatic trimming with a content_resize-family node instead of finding coordinates by hand.
