Image Remap Canvas：Blender 插件

Image Remap Canvas is a Blender Image Editor extension for extracting perspective regions from images. It lets you draw an adjustable quadrilateral over the active image, perspective-correct that region into a square or rectangular patch, arrange multiple patches on a temporary result canvas, and finally save the canvas as a new Blender image datablock.

Features

• Draw and adjust a four-point source selection in the Image Editor.
• Preview perspective-corrected results in real time with GPU textures.
• Place the result canvas to the right of, or below, the source image so the original image remains visible.
• Select, move, resize, uniformly scale, and rotate canvas items with snapped 90-degree rotation.
• Delete committed regions and use undo/redo for edit operations.
• Collect regions from multiple source images in one modal session.
• Save the final result as a Blender image datablock.

Usage

• Open Blender's Image Editor and load an image.
• Open the right sidebar with N, then switch to the Image Remap tab.
• Set the canvas size, patch size, and interpolation mode as needed.
• Click Start Canvas to begin editing.
• Drag the four source selection points over the region you want to extract.
• Use the result canvas to inspect the live patch. Drag canvas items to move them, drag side handles to change width or height, drag corner handles to scale uniformly, or drag the external corner rotation handle to rotate in 90-degree steps.
• Press Enter or click Commit Region to fix the current patch and start collecting another region.
• Select a committed canvas item and press X or Delete to remove it.
