Method Detail

writeCIM

public static void writeCIM(FileHandle file,
                            Pixmap pixmap)

Writes the Pixmap to the given file using a custom compression scheme. First three integers define the width, height and format, remaining bytes are zlib compressed pixels. To be able to load the Pixmap to a Texture, use ".cim" as the file suffix. Throws a GdxRuntimeException in case the Pixmap couldn't be written to the file.

Parameters:

file - the file to write the Pixmap to

readCIM

public static Pixmap readCIM(FileHandle file)

Reads the Pixmap from the given file, assuming the Pixmap was written with the writeCIM(FileHandle, Pixmap) method. Throws a GdxRuntimeException in case the file couldn't be read.

Parameters:

file - the file to read the Pixmap from

writePNG

public static void writePNG(FileHandle file,
                            Pixmap pixmap)

Writes the pixmap as a PNG with compression. See PixmapIO.PNG to configure the compression level, more efficiently flip the pixmap vertically, and to write out multiple PNGs with minimal allocation.
