Image

Inherits: Resource < RefCounted < Object

Image datatype.

Description

Native image datatype. Contains image data which can be converted to an ImageTexture and provides commonly used image processing methods. The maximum width and height for an Image are MAX_WIDTH and MAX_HEIGHT.

An Image cannot be assigned to a texture property of an object directly (such as Sprite2D.texture), and has to be converted manually to an ImageTexture first.

Note: The maximum image size is 16384×16384 pixels due to graphics hardware limitations. Larger images may fail to import.

enum Interpolation: 🔗

Interpolation INTERPOLATE_NEAREST = 0

Performs nearest-neighbor interpolation. If the image is resized, it will be pixelated.

Interpolation INTERPOLATE_BILINEAR = 1

Performs bilinear interpolation. If the image is resized, it will be blurry. This mode is faster than INTERPOLATE_CUBIC, but it results in lower quality.

Interpolation INTERPOLATE_CUBIC = 2

Performs cubic interpolation. If the image is resized, it will be blurry. This mode often gives better results compared to INTERPOLATE_BILINEAR, at the cost of being slower.

Interpolation INTERPOLATE_TRILINEAR = 3

Performs bilinear separately on the two most-suited mipmap levels, then linearly interpolates between them.

It’s slower than 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.

Note: If you intend to scale multiple copies of the original image, it’s better to call 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.

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 0. Enabling 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 has_mipmaps or get_mipmap_count. Calling generate_mipmaps on an image that already has mipmaps will replace existing mipmaps in the image.

See also ImageTexture description for usage examples.

Note: This method is only available in engine builds with the TGA module enabled. By default, the TGA module is enabled, but it can be disabled at build-time using the module_tga_enabled=no SCons option.

Error load_webp_from_buffer(buffer: PackedByteArray) 🔗

Loads an image from the binary contents of a WebP file.

void normal_map_to_xy() 🔗

Error save_exr(path: String, grayscale: bool = false) const 🔗

Saves the image as an EXR file to path. If grayscale is true and the image has only one channel, it will be saved explicitly as monochrome rather than one red channel. This function will return @GlobalScope.ERR_UNAVAILABLE if Godot was compiled without the TinyEXR module.

Note: The TinyEXR module is disabled in non-editor builds, which means save_exr will return @GlobalScope.ERR_UNAVAILABLE when it is called from an exported project.

PackedByteArray save_exr_to_buffer(grayscale: bool = false) const 🔗

Saves the image as an EXR file to a byte array. If grayscale is true 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.

Note: The TinyEXR module is disabled in non-editor builds, which means save_exr will return an empty byte array when it is called from an exported project.

Error save_jpg(path: String, quality: float = 0.75) const 🔗

Saves the image as a JPEG file to path with the specified quality between 0.01 and 1.0 (inclusive). Higher quality values result in better-looking output at the cost of larger file sizes. Recommended quality values are between 0.75 and 0.90. Even at quality 1.00, JPEG compression remains lossy.

Note: 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.

PackedByteArray save_jpg_to_buffer(quality: float = 0.75) const 🔗

Saves the image as a JPEG file to a byte array with the specified quality between 0.01 and 1.0 (inclusive). Higher quality values result in better-looking output at the cost of larger byte array sizes (and therefore memory usage). Recommended quality values are between 0.75 and 0.90. Even at quality 1.00, JPEG compression remains lossy.

Note: 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.

Error save_png(path: String) const 🔗

Saves the image as a PNG file to the file at path.

PackedByteArray save_png_to_buffer() const 🔗

Saves the image as a PNG file to a byte array.

Error save_webp(path: String, lossy: bool = false, quality: float = 0.75) const 🔗

Saves the image as a WebP (Web Picture) file to the file at path. By default it will save lossless. If lossy is true, the image will be saved lossy, using the quality setting between 0.0 and 1.0 (inclusive). Lossless WebP offers more efficient compression than PNG.

Note: The WebP format is limited to a size of 16383×16383 pixels, while PNG can save larger images.

PackedByteArray save_webp_to_buffer(lossy: bool = false, quality: float = 0.75) const 🔗

Saves the image as a WebP (Web Picture) file to a byte array. By default it will save lossless. If lossy is true, the image will be saved lossy, using the quality setting between 0.0 and 1.0 (inclusive). Lossless WebP offers more efficient compression than PNG.

Note: The WebP format is limited to a size of 16383×16383 pixels, while PNG can save larger images.

void set_data(width: int, height: int, use_mipmaps: bool, format: Format, data: PackedByteArray) 🔗

Overwrites data of an existing Image. Non-static equivalent of create_from_data.

void set_pixel(x: int, y: int, color: Color) 🔗

Sets the Color of the pixel at (x, y) to color.

Example:

GDScriptC#

var img_width = 10
var img_height = 5
var img = Image.create(img_width, img_height, false, Image.FORMAT_RGBA8)
img.set_pixel(1, 2, Color.RED) # Sets the color at (1, 2) to red.

int imgWidth = 10;
int imgHeight = 5;
var img = Image.Create(imgWidth, imgHeight, false, Image.Format.Rgba8);
img.SetPixel(1, 2, Colors.Red); // Sets the color at (1, 2) to red.

This is the same as set_pixelv, but with a two integer arguments instead of a Vector2i argument.

void set_pixelv(point: Vector2i, color: Color) 🔗

Sets the Color of the pixel at point to color.

Example:

GDScriptC#

var img_width = 10
var img_height = 5
var img = Image.create(img_width, img_height, false, Image.FORMAT_RGBA8)
img.set_pixelv(Vector2i(1, 2), Color.RED) # Sets the color at (1, 2) to red.

int imgWidth = 10;
int imgHeight = 5;
