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.

Classes

OwnedImage class OwnedImage(COLOR): Manually managed image.

Enums

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.

Functions

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.
convertImageToOwnedImage_l16 OwnedImage!L16 convertImageToOwnedImage_l16(Image image)
convertImageToOwnedImage_l8 OwnedImage!L8 convertImageToOwnedImage_l8(Image image)
convertImageToOwnedImage_rgb8 OwnedImage!RGB convertImageToOwnedImage_rgb8(Image image): Convert and disown gamut Image to OwnedImage. Result: ìmage` is disowned, result is owning the image data.
convertImageToOwnedImage_rgba8 OwnedImage!RGBA convertImageToOwnedImage_rgba8(Image image): Convert and disown gamut Image to OwnedImage. Result: ìmage` is disowned, result is owning the image data.
copyPixels void copyPixels(SRC src, COLOR[] dst): Copy a view's pixels (top-to-bottom) to a COLOR buffer.
copyScanline void copyScanline(SRC src, int y, COLOR[] dst): Copy the indicated row of src to a COLOR buffer.
createViewFromImageRef void createViewFromImageRef(Image view, ImageRef!COLOR source): Make a gamut Image view from a dplug:graphics ImageRef. The original OwnedImage is still the owner of the pixel data.
cropImageRef ImageRef!COLOR cropImageRef(ImageRef!COLOR src, box2i rect)
ImageRef!COLOR cropImageRef(ImageRef!COLOR src, int xmin, int ymin, int xmax, int ymax): Crop an ImageRef and get an ImageRef instead of a Voldemort type. This also avoid adding offset to coordinates.
getImageRef ImageRef!COLOR getImageRef(Image image): On the contrary, get an ImageRef!XXX from a Gamut Image without disowning it.
loadImageSeparateAlpha OwnedImage!RGBA loadImageSeparateAlpha(void[] imageDataRGB, void[] imageDataAlpha): Loads two different images: - the 1st is the RGB channels - the 2nd is interpreted as greyscale and fetch in the alpha channel of the result. The returned OwnedImage!RGBA should be destroyed with destroyFree.
loadImageWithFilledAlpha OwnedImage!RGBA loadImageWithFilledAlpha(void[] imageDataRGB, ubyte alphaValue): Loads two different images: - the 1st is the RGB channels - the 2nd is interpreted as greyscale and fetch in the alpha channel of the result. The returned OwnedImage!RGBA should be destroyed with destroyFree.
loadOwnedImage OwnedImage!RGBA loadOwnedImage(void[] imageData): Loads an image from compressed data. The returned OwnedImage!RGBA should be destroyed with destroyFree.
loadOwnedImageDepth OwnedImage!L16 loadOwnedImageDepth(void[] imageData): Loads an image to be a 16-bit one channel image (OwnedImage!L16). The returned OwnedImage!L16 should be destroyed with destroyFree.
loadOwnedImagePremul OwnedImage!RGBA loadOwnedImagePremul(void[] imageData): Loads an image from compressed data and ensure the alpha is premultiplied. The returned OwnedImage!RGBA should be destroyed with destroyFree.
size void size(V src, int w, int h): Default implementation for the .size method. Asserts that the view has the desired size.
toRef ImageRef!L8 toRef(OwnedImage!L8 src)
ImageRef!L16 toRef(OwnedImage!L16 src)
ImageRef!RGBA toRef(OwnedImage!RGBA src)
ImageRef!RGBA16 toRef(OwnedImage!RGBA16 src): Convert an OwnedImage to an ImageRef.

Mixin templates

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.

Structs

ImageRef struct ImageRef(COLOR): Represents a reference to COLOR data already existing elsewhere in memory. Assumes that pixels are stored row-by-row, with a known distance between each row.
