Method initialLoadImage

processing/processing.go:148–162

initialLoadImage loads a single page/frame of the image. If the image format supports thumbnails and thumbnail loading is enforced, it tries to load the thumbnail first.

(
	img *vips.Image,
	imgdata imagedata.ImageData,
	enforceThumbnail bool,
)

// If the image format supports thumbnails and thumbnail loading is enforced,
// it tries to load the thumbnail first.
func (p *Processor) initialLoadImage(
	img *vips.Image,
	imgdata imagedata.ImageData,
	enforceThumbnail bool,
) (bool, error) {
	if enforceThumbnail && imgdata.Format().SupportsThumbnail() {
		if err := img.LoadThumbnail(imgdata); err == nil {
			return true, nil
		} else {
			slog.Debug(fmt.Sprintf("Can't load thumbnail: %s", err))
		}
	}

	return false, img.Load(imgdata, 1.0, 0, 1)
}

// reloadImageForProcessing reloads the image for processing.
// For animated images, it loads all frames up to MaxAnimationFrames.
