Image Class

Holds all the image's color data in a given format. See ImageFormat constants.

If true, the resource will be made unique in each instance of its local scene. It can thus be modified in a scene instance without impacting other instances of that same scene.

The name of the resource. This is an optional identifier. If ResourceName is not empty, its value will be displayed to represent the current resource in the editor inspector. For built-in scripts, the ResourceName will be displayed as the tab name in the script editor.

The path to the resource. In case it has its own file, it will return its filepath. If it's tied to the scene, it will return the scene's path, followed by the resource's index.

Virtual method which can be overridden to customize the return value of Get(String).

Returns the given property. Returns null if the property does not exist.

Virtual method which can be overridden to customize the return value of GetPropertyList.

Returns the object's property list as an Array of dictionaries.

Each property's Dictionary must contain at least name: String and type: int (see VariantType) entries. Optionally, it can also include hint: int (see PropertyHint), hint_string: String, and usage: int (see PropertyUsageFlags).

Called whenever the object receives a notification, which is identified in what by a constant. The base Object has two constants and , but subclasses such as Node define a lot more notifications which are also received by this method.

Virtual method which can be overridden to customize the return value of Set(String, Object).

Sets a property. Returns true if the property exists.

Virtual function which can be overridden to customize the behavior value of SetupLocalToScene.

Adds a user-defined signal. Arguments are optional, but can be added as an Array of dictionaries, each containing name: String and type: int (see VariantType) entries.

Alpha-blends src_rect from src image to this image at coordinates dest.

Alpha-blends src_rect from src image to this image using mask image at coordinates dst. Alpha channels are required for both src and mask. dst pixels and src pixels will blend if the corresponding mask pixel's alpha value is not 0. src image and mask image must have the same size (width and height) but they can have different formats.

Copies src_rect from src image to this image at coordinates dst.

Blits src_rect area from src image to this image at the coordinates given by dst. src pixel is copied onto dst if the corresponding mask pixel's alpha value is not 0. src image and mask image must 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.

Calls the method on the object and returns the result. This method supports a variable number of arguments, so parameters are passed as a comma separated list. Example:

call("set", "position", Vector2(42.0, 0.0))

Note: In C#, the method name must be specified as snake_case if it is defined by a built-in Godot node. This doesn't apply to user-defined methods where you should use the same convention as in the C# source (typically PascalCase).

Calls the method on the object during idle time. This method supports a variable number of arguments, so parameters are passed as a comma separated list. Example:

call_deferred("set", "position", Vector2(42.0, 0.0))

Note: In C#, the method name must be specified as snake_case if it is defined by a built-in Godot node. This doesn't apply to user-defined methods where you should use the same convention as in the C# source (typically PascalCase).

Calls the method on the object and returns the result. Contrarily to Call(String, Object), this method does not support a variable number of arguments but expects all parameters to be via a single Array.

callv("set", [ "position", Vector2(42.0, 0.0) ])

Returns true if the object can translate strings. See SetMessageTranslation(Boolean) and Tr(String).

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 ImageCompressMode and ImageCompressSource constants.

Connects a signal to a method on a target object. Pass optional binds to the call as an Array of parameters. These parameters will be passed to the method after any parameter used in the call to EmitSignal(String, Object). Use flags to set deferred or one-shot connections. See ObjectConnectFlags constants.

A signal can only be connected once to a method. It will throw an error if already connected, unless the signal was connected with . To avoid this, first, use IsConnected(String, Object, String) to check for existing connections.

If the target is destroyed in the game's lifecycle, the connection will be lost.

Examples:

connect("pressed", self, "_on_Button_pressed") # BaseButton signal
connect("text_entered", self, "_on_LineEdit_text_entered") # LineEdit signal
connect("hit", self, "_on_Player_hit", [ weapon_type, damage ]) # User-defined signal

An example of the relationship between binds passed to Connect(String, Object, String, Array, UInt32) and parameters used when calling EmitSignal(String, Object):

connect("hit", self, "_on_Player_hit", [ weapon_type, damage ]) # weapon_type and damage are passed last
emit_signal("hit", "Dark lord", 5) # "Dark lord" and 5 are passed first
func _on_Player_hit(hit_by, level, weapon_type, damage):
    print("Hit by %s (lvl %d) with weapon %s for %d damage" % [hit_by, level, weapon_type, damage])

Converts the image's format. See ImageFormat constants.

Copies src image to this image.

Creates an empty image of given size and format. See ImageFormat constants. If use_mipmaps is true then generate mipmaps for this image. See the GenerateMipmaps(Boolean).

Creates a new image of given size and format. See ImageFormat constants. Fills the image with the given raw data. If use_mipmaps is true then loads mipmaps for this image from data. See GenerateMipmaps(Boolean).

Crops the image to the given width and height. 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 if the image has data for alpha values. Returns if all the alpha values are stored in a single bit. Returns if no data for alpha values is found.

Disconnects a signal from a method on the given target.

If you try to disconnect a connection that does not exist, the method will throw an error. Use IsConnected(String, Object, String) to ensure that the connection exists.

Duplicates the resource, returning a new resource. By default, sub-resources are shared between resource copies for efficiency. This can be changed by passing true to the subresources argument which will copy the subresources.

Note: If subresources is true, this method will only perform a shallow copy. Nested resources within subresources will not be duplicated and will still be shared.

Emits the changed signal.

If external objects which depend on this resource should be updated, this method must be called manually whenever the state of this resource has changed (such as modification of properties).

The method is equivalent to:

emit_signal("changed")

Note: This method is called automatically for built-in resources.

Emits the given signal. The signal must exist, so it should be a built-in signal of this class or one of its parent classes, or a user-defined signal. This method supports a variable number of arguments, so parameters are passed as a comma separated list. Example:

emit_signal("hit", weapon_type, damage)
emit_signal("game_over")

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.

Deletes the object from memory immediately. For Nodes, you may want to use QueueFree to queue the node for safe deletion at the end of the current frame.

Important: If you have a variable pointing to an object, it will not be assigned to null once the object is freed. Instead, it will point to a previously freed instance and you should validate it with @GDScript.is_instance_valid before attempting to call its methods or access its properties.

Generates mipmaps for the image. Mipmaps are precalculated and lower resolution copies of the image. Mipmaps are automatically used if the image needs to be scaled down when rendered. This improves image quality and the performance of the rendering. Returns an error if the image is compressed, in a custom format or if the image's width/height is 0.

Returns the Variant value of the given property. If the property doesn't exist, this will return null.

Note: In C#, the property name must be specified as snake_case if it is defined by a built-in Godot node. This doesn't apply to user-defined properties where you should use the same convention as in the C# source (typically PascalCase).

Returns the object's class as a String.

Returns a copy of the image's raw data.

Returns the image's format. See ImageFormat constants.

Returns the image's height.

Returns an Array of dictionaries with information about signals that are connected to the object.

Each Dictionary contains three String entries:

- source is a reference to the signal emitter.

- signal_name is the name of the connected signal.

- method_name is the name of the method to which the signal is connected.

Gets the object's property indexed by the given NodePath. The node path should be relative to the current object and can use the colon character (:) to access nested properties. Examples: "position:x" or "material:next_pass:blend_mode".

Returns the object's unique instance ID.

This ID can be saved in EncodedObjectAsID, and can be used to retrieve the object instance with @GDScript.instance_from_id.

If ResourceLocalToScene is enabled and the resource was loaded from a PackedScene instantiation, returns the local scene where this resource's unique copy is in use. Otherwise, returns null.

Returns the object's metadata entry for the given name.

Returns the object's metadata as a String.

Returns the object's methods and their signatures as an Array.

Returns the offset where the image's mipmap with index mipmap is stored in the data dictionary.

Returns the color of the pixel at (x, y) if the image is locked. If the image is unlocked, it always returns a Color with the value (0, 0, 0, 1.0). This is the same as GetPixelv(Vector2), but two integer arguments instead of a Vector2 argument.

Returns the color of the pixel at src if the image is locked. If the image is unlocked, it always returns a Color with the value (0, 0, 0, 1.0). This is the same as GetPixel(Int32, Int32), but with a Vector2 argument instead of two integer arguments.

Returns the object's property list as an Array of dictionaries.

Each property's Dictionary contain at least name: String and type: int (see VariantType) entries. Optionally, it can also include hint: int (see PropertyHint), hint_string: String, and usage: int (see PropertyUsageFlags).

Returns a new image that is a copy of the image's area specified with rect.

Returns the RID of the resource (or an empty RID). Many resources (such as Texture, Mesh, etc) are high-level abstractions of resources stored in a server, so this function will return the original RID.

Returns the object's Script instance, or null if none is assigned.

Returns an Array of connections for the given signal.

Returns the list of signals as an Array of dictionaries.

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 true if a metadata entry is found with the given name.

Returns true if the object contains the given method.

Returns true if the image has generated mipmaps.

Returns true if the given signal exists.

Returns true if the given user-defined signal exists. Only signals added using AddUserSignal(String, Array) are taken into account.

Initializes the internal reference counter. Use this only if you really know what you are doing.

Returns whether the initialization was successful.

Returns true if signal emission blocking is enabled.

Returns true if the object inherits from the given class.

Returns true if the image is compressed.

Returns true if a connection exists for a given signal, target, and method.

Returns true if the image has no data.

Returns true if all the image's pixels have an alpha value of 0. Returns false if any pixel has an alpha value higher than 0.

Returns true if the QueueFree method was called for the object.

Loads an image from file path. See Supported image formats for a list of supported image formats and limitations.

Warning: 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 user:// 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.

Note: 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.

Send a given notification to the object, which will also trigger a call to the _Notification(Int32) method of all classes that the object inherits from.

If reversed is true, _Notification(Int32) is called first on the object's own class, and then up to its successive parent classes. If reversed is false, _Notification(Int32) is called first on the highest ancestor (Object itself), and then down to its successive inheriting classes.

Multiplies color values with alpha values. Resulting color values for a pixel are (color * alpha)/256.

Notify the editor that the property list has changed, so that editor plugins can take the new values into account. Does nothing on export builds.

Increments the internal reference counter. Use this only if you really know what you are doing.

Returns true if the increment was successful, false otherwise.

Removes a given entry from the object's metadata. See also SetMeta(String, Object).

Resizes the image to the given width and height. New pixels are calculated using the interpolation mode defined via ImageInterpolation constants.

Resizes the image to the nearest power of 2 for the width and height. If square is true then set width and height to be the same. New pixels are calculated using the interpolation mode defined via ImageInterpolation constants.

Converts a standard RGBE (Red Green Blue Exponent) image to an sRGB image.

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 if Godot was compiled without the TinyEXR module.

Saves the image as a PNG file to path.

Assigns a new value to the given property. If the property does not exist, nothing will happen.

Note: In C#, the property name must be specified as snake_case if it is defined by a built-in Godot node. This doesn't apply to user-defined properties where you should use the same convention as in the C# source (typically PascalCase).

If set to true, signal emission is blocked.

Assigns a new value to the given property, after the current frame's physics step. This is equivalent to calling Set(String, Object) via CallDeferred(String, Object), i.e. call_deferred("set", property, value).

Note: In C#, the property name must be specified as snake_case if it is defined by a built-in Godot node. This doesn't apply to user-defined properties where you should use the same convention as in the C# source (typically PascalCase).

Assigns a new value to the property identified by the NodePath. The node path should be relative to the current object and can use the colon character (:) to access nested properties. Example:

set_indexed("position", Vector2(42, 0))
set_indexed("position:y", -10)
print(position) # (42, -10)

Defines whether the object can translate strings (with calls to Tr(String)). Enabled by default.

Adds, changes or removes a given entry in the object's metadata. Metadata are serialized and can take any Variant value.

To remove a given entry from the object's metadata, use RemoveMeta(String). Metadata is also removed if its value is set to null. This means you can also use set_meta("name", null) to remove metadata for "name".

Sets the Color of the pixel at (x, y) if the image is locked. Example:

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

Sets the Color of the pixel at (dst.x, dst.y) if the image is locked. Note that the dst values must be integers. Example:

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

Assigns a script to the object. Each object can have a single script assigned to it, which are used to extend its functionality.

If the object already had a script, the previous script instance will be freed and its variables and state will be lost. The new script's method will be called.

This method is called when a resource with ResourceLocalToScene enabled is loaded from a PackedScene instantiation. Its behavior can be customized by overriding _SetupLocalToScene from script.

For most resources, this method performs no base logic. ViewportTexture performs custom logic to properly set the proxy texture and flags in the local viewport.

Shrinks the image by a factor of 2.

Converts the raw data from the sRGB colorspace to a linear scale.

Sets the path of the resource, potentially overriding an existing cache entry for this path. This differs from setting ResourcePath, as the latter would error out if another resource was already cached for the given path.

Translates a message using translation catalogs configured in the Project Settings.

Only works if message translation is enabled (which it is by default), otherwise it returns the message unchanged. See SetMessageTranslation(Boolean).

Unlocks the data and prevents changes.

Decrements the internal reference counter. Use this only if you really know what you are doing.

Returns true if the decrement was successful, false otherwise.

The maximal height allowed for Image resources.

The maximal width allowed for Image resources.
