createCompatibleImage back to summary

createCompatibleImage	back to summary
public static BufferedImage createCompatibleImage(final int width, final int height) Creates a `BufferedImage` with a pixel format compatible with the graphics environment. The returned image can thus benefit from hardware accelerated operations in Java2D API. Parameters width:int The width of the image to be created height:int The height of the image to be created Returns:BufferedImage A instance of `BufferedImage` with a type compatible with the graphics card.

public static BufferedImage createCompatibleImage(final int width, final int height)

Creates a BufferedImage with a pixel format compatible with the graphics environment. The returned image can thus benefit from hardware accelerated operations in Java2D API.

Parameters

width:int: The width of the image to be created
height:int: The height of the image to be created

Returns:BufferedImage

A instance of BufferedImage with a type compatible with the graphics card.

createThumbnail back to summary

createThumbnail	back to summary
public static BufferedImage createThumbnail(final BufferedImage image, final int thumbWidth) Creates a thumbnail from an image. A thumbnail is a scaled down version of the original picture. This method will retain the width to height ratio of the original picture and return a new instance of `BufferedImage`. The original picture is not modified. Parameters image:BufferedImage The original image to sample down thumbWidth:int The width of the thumbnail to be created Returns:BufferedImage A thumbnail with the requested width or the original picture if thumbWidth = image.getWidth() Exceptions IllegalArgumentException: If thumbWidth is greater than image.getWidth()

public static BufferedImage createThumbnail(final BufferedImage image, final int thumbWidth)

Creates a thumbnail from an image. A thumbnail is a scaled down version of the original picture. This method will retain the width to height ratio of the original picture and return a new instance of BufferedImage. The original picture is not modified.

Parameters

image:BufferedImage: The original image to sample down
thumbWidth:int: The width of the thumbnail to be created

Returns:BufferedImage

A thumbnail with the requested width or the original picture if thumbWidth = image.getWidth()

Exceptions

IllegalArgumentException:: If thumbWidth is greater than image.getWidth()

flipImageVertically	back to summary
public static void flipImageVertically(final BufferedImage image) Flips the supplied BufferedImage vertically. This is often a necessary conversion step to display a Java2D image correctly with OpenGL and vice versa.
