		Image datatype.
	</brief_description>
	<description>
		Native image datatype. Contains image data which can be converted to an [ImageTexture] and provides commonly used [i]image processing[/i] methods. The maximum width and height for an [Image] are [constant MAX_WIDTH] and [constant MAX_HEIGHT].
		An [Image] cannot be assigned to a texture property of an object directly (such as [member Sprite2D.texture]), and has to be converted manually to an [ImageTexture] first.
		[b]Note:[/b] Methods that modify the image data cannot be used on VRAM-compressed images. Use [method decompress] to convert the image to an uncompressed format first.
		[b]Note:[/b] The maximum image size is 16384×16384 pixels due to graphics hardware limitations. Larger images may fail to import.

		<method name="generate_mipmaps">
			<return type="int" enum="Error" />
			<param index="0" name="renormalize" type="bool" default="false" />
			<description>
				Generates mipmaps for the image. Mipmaps are precalculated lower-resolution copies of the image that are automatically used if the image needs to be scaled down when rendered. They help improve image quality and performance when rendering. This method returns an error if the image is compressed, in a custom format, or if the image's width/height is [code]0[/code]. Enabling [param renormalize] when generating mipmaps for normal map textures will make sure all resulting vector values are normalized.
				It is possible to check if the image has mipmaps by calling [method has_mipmaps] or [method get_mipmap_count]. Calling [method generate_mipmaps] on an image that already has mipmaps will replace existing mipmaps in the image.

				Saves the image as a DDS (DirectDraw Surface) file to a byte array. DDS is a container format that can store textures in various compression formats, such as DXT1, DXT5, or BC7. This function will return an empty byte array if Godot was compiled without the DDS module.
				[b]Note:[/b] The DDS module may be disabled in certain builds, which means [method save_dds_to_buffer] will return an empty byte array when it is called from an exported project.

Set [param color_image] to [code]true[/code] when saving a color image, such as a screenshot.

		<constant name="INTERPOLATE_BILINEAR" value="1" enum="Interpolation">
			Performs bilinear interpolation. If the image is resized, it will be blurry. This mode is faster than [constant INTERPOLATE_CUBIC], but it results in lower quality.
		</constant>
		<constant name="INTERPOLATE_CUBIC" value="2" enum="Interpolation">
			Performs cubic interpolation. If the image is resized, it will be blurry. This mode often gives better results compared to [constant INTERPOLATE_BILINEAR], at the cost of being slower.
		</constant>
		<constant name="INTERPOLATE_TRILINEAR" value="3" enum="Interpolation">
			Performs bilinear separately on the two most-suited mipmap levels, then linearly interpolates between them.
			It's slower than [constant INTERPOLATE_BILINEAR], but produces higher-quality results with far fewer aliasing artifacts.
			If the image does not have mipmaps, they will be generated and used internally, but no mipmaps will be generated on the resulting image.
			[b]Note:[/b] If you intend to scale multiple copies of the original image, it's better to call [method generate_mipmaps]] on it in advance, to avoid wasting processing power in generating them again and again.
			On the other hand, if the image already has mipmaps, they will be used, and a new set will be generated for the resulting image.
		</constant>
		<constant name="INTERPOLATE_LANCZOS" value="4" enum="Interpolation">
			Performs Lanczos interpolation. This is the slowest image resizing mode, but it typically gives the best results, especially when downscaling images.
		</constant>
		<constant name="ALPHA_NONE" value="0" enum="AlphaMode">
			Image is fully opaque. It does not store alpha data.
		</constant>
		<constant name="ALPHA_BIT" value="1" enum="AlphaMode">
			Image stores either fully opaque or fully transparent pixels. Also known as punchthrough alpha.
		</constant>
		<constant name="ALPHA_BLEND" value="2" enum="AlphaMode">
			Image stores alpha data with values varying between [code]0.0[/code] and [code]1.0[/code].
		</constant>
		<constant name="COMPRESS_S3TC" value="0" enum="CompressMode">
			Use S3TC compression.
		</constant>
		<constant name="COMPRESS_ETC" value="1" enum="CompressMode">
			Use ETC compression.
		</constant>
		<constant name="COMPRESS_ETC2" value="2" enum="CompressMode">
			Use ETC2 compression.
		</constant>
		<constant name="COMPRESS_BPTC" value="3" enum="CompressMode">
			Use BPTC compression.
		</constant>
		<constant name="COMPRESS_ASTC" value="4" enum="CompressMode">
			Use ASTC compression.
		</constant>
		<constant name="COMPRESS_MAX" value="5" enum="CompressMode">
			Represents the size of the [enum CompressMode] enum.
		</constant>
		<constant name="USED_CHANNELS_L" value="0" enum="UsedChannels">
			The image only uses one channel for luminance (grayscale).
		</constant>
		<constant name="USED_CHANNELS_LA" value="1" enum="UsedChannels">
			The image uses two channels for luminance and alpha, respectively.
		</constant>
		<constant name="USED_CHANNELS_R" value="2" enum="UsedChannels">
			The image only uses the red channel.
		</constant>
		<constant name="USED_CHANNELS_RG" value="3" enum="UsedChannels">
			The image uses two channels for red and green.
		</constant>
		<constant name="USED_CHANNELS_RGB" value="4" enum="UsedChannels">
			The image uses three channels for red, green, and blue.
		</constant>
		<constant name="USED_CHANNELS_RGBA" value="5" enum="UsedChannels">
			The image uses four channels for red, green, blue, and alpha.
		</constant>
		<constant name="COMPRESS_SOURCE_GENERIC" value="0" enum="CompressSource">
			Source texture (before compression) is a regular texture. Default for all textures.
		</constant>
		<constant name="COMPRESS_SOURCE_SRGB" value="1" enum="CompressSource">
			Source texture (before compression) uses nonlinear sRGB encoding.
		</constant>
		<constant name="COMPRESS_SOURCE_NORMAL" value="2" enum="CompressSource">
			Source texture (before compression) is a normal texture (e.g. it can be compressed into two channels).
		</constant>
		<constant name="ASTC_FORMAT_4x4" value="0" enum="ASTCFormat">
			Hint to indicate that the high quality 4×4 ASTC compression format should be used.
		</constant>
		<constant name="ASTC_FORMAT_8x8" value="1" enum="ASTCFormat">
			Hint to indicate that the low quality 8×8 ASTC compression format should be used.
		</constant>
