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 [code]texture[/code] property of an object directly (such as [Sprite2D]), and has to be converted manually to an [ImageTexture] first.
[b]Note:[/b] The maximum image size is 16384×16384 pixels due to graphics hardware limitations. Larger images may fail to import.
Alpha-blends [code]src_rect[/code] from [code]src[/code] image to this image at coordinates [code]dest[/code], clipped accordingly to both image bounds. This image and [code]src[/code] image [b]must[/b] have the same format. [code]src_rect[/code] with not positive size is treated as empty.
Alpha-blends [code]src_rect[/code] from [code]src[/code] image to this image using [code]mask[/code] image at coordinates [code]dst[/code], clipped accordingly to both image bounds. Alpha channels are required for both [code]src[/code] and [code]mask[/code]. [code]dst[/code] pixels and [code]src[/code] pixels will blend if the corresponding mask pixel's alpha value is not 0. This image and [code]src[/code] image [b]must[/b] have the same format. [code]src[/code] image and [code]mask[/code] image [b]must[/b] have the same size (width and height) but they can have different formats. [code]src_rect[/code] with not positive size is treated as empty.
Copies [code]src_rect[/code] from [code]src[/code] image to this image at coordinates [code]dst[/code], clipped accordingly to both image bounds. This image and [code]src[/code] image [b]must[/b] have the same format. [code]src_rect[/code] with not positive size is treated as empty.
Blits [code]src_rect[/code] area from [code]src[/code] image to this image at the coordinates given by [code]dst[/code], clipped accordingly to both image bounds. [code]src[/code] pixel is copied onto [code]dst[/code] if the corresponding [code]mask[/code] pixel's alpha value is not 0. This image and [code]src[/code] image [b]must[/b] have the same format. [code]src[/code] image and [code]mask[/code] image [b]must[/b] have the same size (width and height) but they can have different formats. [code]src_rect[/code] with not positive size is treated as empty.
Compresses the image to use less memory. Can not directly access pixel data while the image is compressed. Returns error if the chosen compression mode is not available. See [enum CompressMode] and [enum CompressSource] constants.
Creates an empty image of given size and format. See [enum Format] constants. If [code]use_mipmaps[/code] is [code]true[/code] then generate mipmaps for this image. See the [method generate_mipmaps].
Creates a new image of given size and format. See [enum Format] constants. Fills the image with the given raw data. If [code]use_mipmaps[/code] is [code]true[/code] then loads mipmaps for this image from [code]data[/code]. See [method generate_mipmaps].
Crops the image to the given [code]width[/code] and [code]height[/code]. If the specified size is larger than the current size, the extra area is filled with black pixels.
Decompresses the image if it is VRAM compressed in a supported format. Returns [constant OK] if the format is supported, otherwise [constant ERR_UNAVAILABLE].
Returns [constant ALPHA_BLEND] if the image has data for alpha values. Returns [constant ALPHA_BIT] if all the alpha values are stored in a single bit. Returns [constant ALPHA_NONE] if no data for alpha values is found.
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].
[b]Note:[/b] Mipmap generation is done on the CPU, is single-threaded and is [i]always[/i] done on the main thread. This means generating mipmaps will result in noticeable stuttering during gameplay, even if [method generate_mipmaps] is called from a [Thread].
Returns [code]true[/code] if all the image's pixels have an alpha value of 0. Returns [code]false[/code] if any pixel has an alpha value higher than 0.
Loads an image from file [code]path[/code]. See [url=$DOCS_URL/tutorials/assets_pipeline/importing_images.html#supported-image-formats]Supported image formats[/url] for a list of supported image formats and limitations.
[b]Warning:[/b] This method should only be used in the editor or in cases when you need to load external images at run-time, such as images located at the [code]user://[/code] directory, and may not work in exported projects.
See also [ImageTexture] description for usage examples.
Converts the image's data to represent coordinates on a 3D plane. This is used when the image represents a normal map. A normal map can add lots of detail to a 3D surface without increasing the polygon count.
Resizes the image to the given [code]width[/code] and [code]height[/code]. New pixels are calculated using the [code]interpolation[/code] mode defined via [enum Interpolation] constants.
Resizes the image to the nearest power of 2 for the width and height. If [code]square[/code] is [code]true[/code] then set width and height to be the same. New pixels are calculated using the [code]interpolation[/code] mode defined via [enum Interpolation] constants.
Rotates the image in the specified [code]direction[/code] by [code]90[/code] degrees. The width and height of the image must be greater than [code]1[/code]. If the width and height are not equal, the image will be resized.
Saves the image as an EXR file to [code]path[/code]. If [code]grayscale[/code] is [code]true[/code] and the image has only one channel, it will be saved explicitly as monochrome rather than one red channel. This function will return [constant ERR_UNAVAILABLE] if Godot was compiled without the TinyEXR module.
[b]Note:[/b] The TinyEXR module is disabled in non-editor builds, which means [method save_exr] will return [constant ERR_UNAVAILABLE] when it is called from an exported project.
Saves the image as an EXR file to a byte array. If [code]grayscale[/code] is [code]true[/code] and the image has only one channel, it will be saved explicitly as monochrome rather than one red channel. This function will return an empty byte array if Godot was compiled without the TinyEXR module.
[b]Note:[/b] The TinyEXR module is disabled in non-editor builds, which means [method save_exr] will return an empty byte array when it is called from an exported project.
Saves the image as a JPEG file to [code]path[/code] with the specified [code]quality[/code] between [code]0.01[/code] and [code]1.0[/code] (inclusive). Higher [code]quality[/code] values result in better-looking output at the cost of larger file sizes. Recommended [code]quality[/code] values are between [code]0.75[/code] and [code]0.90[/code]. Even at quality [code]1.00[/code], JPEG compression remains lossy.
[b]Note:[/b] JPEG does not save an alpha channel. If the [Image] contains an alpha channel, the image will still be saved, but the resulting JPEG file won't contain the alpha channel.
Saves the image as a JPEG file to a byte array with the specified [code]quality[/code] between [code]0.01[/code] and [code]1.0[/code] (inclusive). Higher [code]quality[/code] values result in better-looking output at the cost of larger byte array sizes (and therefore memory usage). Recommended [code]quality[/code] values are between [code]0.75[/code] and [code]0.90[/code]. Even at quality [code]1.00[/code], JPEG compression remains lossy.
[b]Note:[/b] JPEG does not save an alpha channel. If the [Image] contains an alpha channel, the image will still be saved, but the resulting byte array won't contain the alpha channel.
Saves the image as a WebP (Web Picture) file to the file at [code]path[/code]. By default it will save lossless. If [code]lossy[/code] is true, the image will be saved lossy, using the [code]quality[/code] setting between 0.0 and 1.0 (inclusive).

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.
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.
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.
