Image datatype. 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 [Sprite]), 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. $DOCS_URL/getting_started/workflow/assets/importing_images.html Alpha-blends [code]src_rect[/code] from [code]src[/code] image to this image at coordinates [code]dest[/code]. Alpha-blends [code]src_rect[/code] from [code]src[/code] image to this image using [code]mask[/code] image at coordinates [code]dst[/code]. 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. [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. Copies [code]src_rect[/code] from [code]src[/code] image to this image at coordinates [code]dst[/code]. Blits [code]src_rect[/code] area from [code]src[/code] image to this image at the coordinates given by [code]dst[/code]. [code]src[/code] pixel is copied onto [code]dst[/code] if the corresponding [code]mask[/code] pixel's alpha value is not 0. [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. Converts a bumpmap to a normalmap. A bumpmap provides a height offset per-pixel, while a normalmap provides a normal direction per pixel. Removes the image's mipmaps. 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. Converts the image's format. See [enum Format] constants. Copies [code]src[/code] image to this image. 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 compressed. Returns an error if decompress function is not available. 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. Stretches the image and enlarges it by a factor of 2. No interpolation is done. Fills the image with a given [Color]. Blends low-alpha pixels with nearby pixels. Flips the image horizontally. Flips the image vertically. 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 a copy of the image's raw data. Returns the image's format. See [enum Format] constants. Returns the image's height. Returns the offset where the image's mipmap with index [code]mipmap[/code] is stored in the [code]data[/code] dictionary. Returns the color of the pixel at [code](x, y)[/code] if the image is locked. If the image is unlocked, it always returns a [Color] with the value [code](0, 0, 0, 1.0)[/code]. This is the same as [method get_pixelv], but two integer arguments instead of a Vector2 argument. Returns the color of the pixel at [code]src[/code] if the image is locked. If the image is unlocked, it always returns a [Color] with the value [code](0, 0, 0, 1.0)[/code]. This is the same as [method get_pixel], but with a Vector2 argument instead of two integer arguments. Returns a new image that is a copy of the image's area specified with [code]rect[/code]. Returns the image's size (width and height). Returns a [Rect2] enclosing the visible portion of the image, considering each pixel with a non-zero alpha channel as visible. Returns the image's width. Returns [code]true[/code] if the image has generated mipmaps. Returns [code]true[/code] if the image is compressed. Returns [code]true[/code] if the image has no data. 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/getting_started/workflow/assets/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. Loads an image from the binary contents of a BMP file. [b]Note:[/b] Godot's BMP module doesn't support 16-bit per pixel images. Only 1-bit, 4-bit, 8-bit, 24-bit, and 32-bit per pixel images are supported. Loads an image from the binary contents of a JPEG file. Loads an image from the binary contents of a PNG file. Loads an image from the binary contents of a TGA file. Loads an image from the binary contents of a WebP file. Locks the data for reading and writing access. Sends an error to the console if the image is not locked when reading or writing a pixel. Converts the image's data to represent coordinates on a 3D plane. This is used when the image represents a normalmap. A normalmap can add lots of detail to a 3D surface without increasing the polygon count. Multiplies color values with alpha values. Resulting color values for a pixel are [code](color * alpha)/256[/code]. 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. Converts a standard RGBE (Red Green Blue Exponent) image to an sRGB image. 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 a PNG file to [code]path[/code]. Sets the [Color] of the pixel at [code](x, y)[/code] if the image is locked. Example: [codeblock] var img = Image.new() img.create(img_width, img_height, false, Image.FORMAT_RGBA8) img.lock() img.set_pixel(x, y, color) # Works img.unlock() img.set_pixel(x, y, color) # Does not have an effect [/codeblock] Sets the [Color] of the pixel at [code](dst.x, dst.y)[/code] if the image is locked. Note that the [code]dst[/code] values must be integers. Example: [codeblock] var img = Image.new() img.create(img_width, img_height, false, Image.FORMAT_RGBA8) img.lock() img.set_pixelv(Vector2(x, y), color) # Works img.unlock() img.set_pixelv(Vector2(x, y), color) # Does not have an effect [/codeblock] Shrinks the image by a factor of 2. Converts the raw data from the sRGB colorspace to a linear scale. Unlocks the data and prevents changes. Holds all the image's color data in a given format. See [enum Format] constants.

The [url=https://en.wikipedia.org/wiki/S3_Texture_Compression]S3TC[/url] texture format that uses Block Compression 1, and is the smallest variation of S3TC, only providing 1 bit of alpha and color data being premultiplied with alpha. [b]Note:[/b] When creating an [ImageTexture], an sRGB to linear color space conversion is performed. The [url=https://en.wikipedia.org/wiki/S3_Texture_Compression]S3TC[/url] texture format that uses Block Compression 2, and color data is interpreted as not having been premultiplied by alpha. Well suited for images with sharp alpha transitions between translucent and opaque areas. [b]Note:[/b] When creating an [ImageTexture], an sRGB to linear color space conversion is performed.

[b]Note:[/b] When creating an [ImageTexture], an sRGB to linear color space conversion is performed. Same as [url=https://en.wikipedia.org/wiki/PVRTC]PVRTC2[/url], but with an alpha component. Similar to [url=https://en.wikipedia.org/wiki/PVRTC]PVRTC2[/url], but with 4-bit color depth and no alpha. Same as [url=https://en.wikipedia.org/wiki/PVRTC]PVRTC4[/url], but with an alpha component. [url=https://en.wikipedia.org/wiki/Ericsson_Texture_Compression#ETC1]Ericsson Texture Compression format 1[/url], also referred to as "ETC1", and is part of the OpenGL ES graphics standard. This format cannot store an alpha channel.

[b]Note:[/b] When creating an [ImageTexture], an sRGB to linear color space conversion is performed. Represents the size of the [enum Format] enum. Performs nearest-neighbor interpolation. If the image is resized, it will be pixelated. 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. 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. Performs Lanczos interpolation. This is the slowest image resizing mode, but it typically gives the best results, especially when downscalng images. Image does not have alpha. Image stores alpha in a single bit. Image uses alpha. Use S3TC compression. Use PVRTC2 compression. Use PVRTC4 compression. Use ETC compression. Use ETC2 compression. Source texture (before compression) is a regular texture. Default for all textures. Source texture (before compression) is in sRGB space. Source texture (before compression) is a normal texture (e.g. it can be compressed into two channels).
