Full Changelog: v1.2.0...v1.2.1

Optional Output Parameters Support

vipsgen v1.2.0 introduces optional output parameters for common argument types. See examples.

Smartcrop with Attention Coordinates

Operation: vips_smartcrop
Optional Outputs: AttentionX, AttentionY

The coordinates where the algorithm detected the most interesting content for cropping.

options := vips.DefaultSmartcropOptions()
err := img.Smartcrop(width, height, options)

// Access the attention coordinates
fmt.Printf("Attention Center: x=%d, y=%d\n", options.AttentionX, options.AttentionY)

Mosaic with Transformation Parameters

Operation: vips_mosaic
Optional Outputs: Dx0, Dy0, Scale1, Angle1, Dx1, Dy1

The detected transformation parameters when combining two images.

options := vips.DefaultMosaicOptions()
err := img1.Mosaic(img2, direction, xref, yref, xsec, ysec, options)

// Access transformation parameters
fmt.Printf("Integer Offset: dx0=%d, dy0=%d\n", options.Dx0, options.Dy0)
fmt.Printf("Detected Scale: %.3f\n", options.Scale1)
fmt.Printf("Detected Rotation: %.3f degrees\n", options.Angle1)
