Method Detail

setInSampleSize

public void setInSampleSize(int inSampleSize)

If set to a value > 1, requests the decoder to subsample the original frames, returning a smaller frame buffer to save memory. The sample size is the number of pixels in either dimension that correspond to a single pixel in the decoded bitmap. For example, inSampleSize == 4 returns an image that is 1/4 the width/height of the original, and 1/16 the number of pixels. Values outside range <1, 65635> are treated as 1. Unlike BitmapFactory.Options.inSampleSize values which are not powers of 2 are also supported. Default value is 1.

Parameters:

inSampleSize - the sample size

setInIsOpaque

public void setInIsOpaque(boolean inIsOpaque)

Indicates whether the content is opaque. GIF that is known to be opaque can take a faster drawing case than non-opaque one, since alpha channel processing may be skipped.

Common usage is setting this to true when view where GIF is displayed is known to be non-transparent and its background is irrelevant.In such case even if GIF contains transparent areas, they will appear black.

See also GifTextureView.setOpaque(boolean). Default value is false, which means that content can be transparent.

Parameters:

inIsOpaque - whether the content is opaque
