Expand description

A trait for manipulating images.

Associated Types

Underlying image type. This is mainly used by SubImages in order to always have a reference to the original image. This allows for less indirections and it eases the use of nested SubImages.

Required methods

Gets a reference to the mutable pixel at location (x, y). Indexed from top left.

Panics

Panics if (x, y) is out of bounds.

Put a pixel at location (x, y). Indexed from top left.

Panics

Panics if (x, y) is out of bounds.

Put a pixel at location (x, y), taking into account alpha channels

DEPRECATED: This method will be removed. Blend the pixel directly instead.

Returns a mutable reference to the underlying image.

Provided methods

Puts a pixel at location (x, y). Indexed from top left.

This function can be implemented in a way that ignores bounds checking.

Safety

The coordinates must be in_bounds of the image.

Copies all of the pixels from another image into this image.

The other image is copied with the top-left corner of the other image placed at (x, y).

In order to copy only a piece of the other image, use GenericImageView::view.

You can use FlatSamples to source pixels from an arbitrary regular raster of channel values, for example from a foreign interface or a fixed image.

Returns

Returns an error if the image is too large to be copied at the given position

Copies all of the pixels from one part of this image to another part of this image.

The destination rectangle of the copy is specified with the top-left corner placed at (x, y).

Returns

true if the copy was successful, false if the image could not be copied due to size constraints.

Returns a mutable subimage that is a view into this image. If you want an immutable subimage instead, use GenericImageView::view The coordinates set the position of the top left corner of the SubImage.
