Method reloadImageForProcessing

processing/processing.go:166–181

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

(
	img *vips.Image,
	imgdata imagedata.ImageData,
	po ProcessingOptions,
	asAnimated bool,
)

// reloadImageForProcessing reloads the image for processing.
// For animated images, it loads all frames up to MaxAnimationFrames.
func (p *Processor) reloadImageForProcessing(
	img *vips.Image,
	imgdata imagedata.ImageData,
	po ProcessingOptions,
	asAnimated bool,
) error {
	// If we are going to process the image as animated, we need to load all frames
	// up to MaxAnimationFrames
	if asAnimated {
		frames := min(img.Pages(), po.MaxAnimationFrames())
		return img.Load(imgdata, 1.0, 0, frames)
	}

	// Otherwise, we just need to remove any animation-related data
	return img.RemoveAnimation()
}

// checkImageSize checks the image dimensions and number of frames against security options.
// It returns the image width, height and a security check error, if any.
