A View is the base abstraction for images. Port of ae.utils.graphics.

Public Imports

ViewColor alias ViewColor(T) = typeof(T.init[0, 0]): Returns the color type of the specified view. By convention, colors are structs with numeric fields named after the channel they indicate.

isDirectView eponymoustemplate isDirectView(T): Optionally, a view can also provide direct pixel access. We call these "direct views".
isView eponymoustemplate isView(T): A view is any type which provides a width, height, and can be indexed to get the color at a specific coordinate.
isWritableView eponymoustemplate isWritableView(T): Views can be read-only or writable.

blitTo void blitTo(SRC src, DST dst): Blits a view onto another. The views must have the same size.
blitTo void blitTo(SRC src, DST dst, int x, int y): Helper function to blit an image onto another at a specified location.
crop auto crop(V src, int x0, int y0, int x1, int y1): Crop a view to the specified rectangle.
onePixel auto onePixel(COLOR c): Return a 1x1 view of the specified color. Useful for testing.
size void size(V src, int w, int h): Default implementation for the .size method. Asserts that the view has the desired size.
solid auto solid(COLOR c, int w, int h): Returns a view of the specified dimensions and same solid color.

DirectView mixintemplate DirectView(): Mixin which implements view primitives on top of existing direct view primitives.
Warp mixintemplate Warp(V): Mixin which implements view primitives on top of another view, using a coordinate transform function.

procedural template procedural(alias formula): Returns a view which calculates pixels on-demand using the specified formula.
