As of Godot 3.0, HQ2X is no longer used to upscale the editor theme and icons on hiDPI displays, which limited its effective uses. HQ2X was also used to upscale the project theme when the "Use Hidpi" project setting was enabled, but results were often less than ideal. The new StyleBoxFlat and SVG support also make HQ2X less important to have as a core feature. This decreases binary sizes slightly (-150 KB on most platforms, -212 KB on WebAssembly release). This partially addresses #12419.

Native image datatype. Contains image data, which can be converted to a [Texture2D], and several functions to interact with it. The maximum width and height for an [Image] are [constant MAX_WIDTH] and [constant MAX_HEIGHT].
|
||
[b]Note:[/b] The maximum image size is 16384×16384 pixels due to graphics hardware limitations. Larger images will fail to import.
