OwnedImage class OwnedImage(COLOR): Manually managed image which is also GC-proof.

aaFillSector void aaFillSector(V v, float x, float y, float r0, float r1, float a0, float a1, COLOR c): Rough anti-aliased fillsector
aaSoftCircle void aaSoftCircle(V v, float x, float y, float r1, float r2, float r3, COLOR color, float globalAlpha): Draw a circle gradually fading in between r1 and r2 and fading out between r2 and r3
blendWithAlpha void blendWithAlpha(SRC srcView, DST dstView, ImageRef!L8 alphaView): Blits a view onto another. The views must have the same size. PERF: optimize that
crop auto crop(V src, box2i b): Crop a view from a box2i
cropImageRef ImageRef!COLOR cropImageRef(ImageRef!COLOR src, box2i rect): Crop an ImageRef and get an ImageRef instead of a Voldemort type. This also avoid adding offset to coordinates.
horizontalSlope void horizontalSlope(V v, box2i rect, COLOR c0, COLOR c1): Fill rectangle while interpolating a color horiontally
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 OwnedImage is allocated with mallocEmplace and should be destroyed with destroyFree.
loadOwnedImage OwnedImage!RGBA loadOwnedImage(void[] imageData): The one function you probably want to use. Loads an image from a static array. The OwnedImage is allocated with mallocEmplace and should be destroyed with destroyFree.
