Method Detail

scaleToSize

public static Pix scaleToSize(Pix pixs,
                              int width,
                              int height,
                              com.googlecode.leptonica.android.Scale.ScaleType type)

Scales the Pix to a specified width and height using a specified scaling type (fill, stretch, etc.). Returns a scaled image or a clone of the Pix if no scaling is required.

Parameters:

pixs - Source pix image

width - The desired width to scale to

height - The desired height to scale to

type - The desired scaling type

Returns:

org.jetbrains.dokka.NodeRenderContent@1b79d51d: a scaled image or a clone of the Pix if no scaling is required

scale

public static Pix scale(Pix pixs,
                        float scale)

Scales the Pix to specified scale. If no scaling is required, returns a clone of the source Pix.

Parameters:

pixs - the source Pix

scale - dimension scaling factor

Returns:

org.jetbrains.dokka.NodeRenderContent@2815b505: a Pix scaled according to the supplied factors

scaleWithoutSharpening

public static Pix scaleWithoutSharpening(Pix pixs,
                                         float scale)

Scales the Pix to the specified scale without sharpening.

Parameters:

pixs - the source Pix (1, 2, 4, 8, 16 and 32 bpp)

scale - scaling factor for both X and Y

Returns:

org.jetbrains.dokka.NodeRenderContent@4f9fbc4b: a Pix scaled while maintaining its aspect ratio

scale

public static Pix scale(Pix pixs,
                        float scaleX,
                        float scaleY)

Scales the Pix to specified x and y scale. If no scaling is required, returns a clone of the source Pix.

Parameters:

pixs - the source Pix

scaleX - x-dimension (width) scaling factor

scaleY - y-dimension (height) scaling factor

Returns:

org.jetbrains.dokka.NodeRenderContent@59b5af16: a Pix scaled according to the supplied factors
