Implementations

[src]
impl<DeepOrFlatSamples> ReadLargestLevel<DeepOrFlatSamples>
[src]pub fn all_channels(self) -> ReadAnyChannels<DeepOrFlatSamples>
[src]
pub fn all_channels(self) -> ReadAnyChannels<DeepOrFlatSamples>
[src]Read all arbitrary channels in each layer.
pub fn rgba_channels<R, G, B, A, Create, Set, Pixels>(
self,
create_pixels: Create,
set_pixel: Set
) -> CollectPixels<ReadOptionalChannel<ReadRequiredChannel<ReadRequiredChannel<ReadRequiredChannel<NoneMore, R>, G>, B>, A>, (R, G, B, A), Pixels, Create, Set> where
R: FromNativeSample,
G: FromNativeSample,
B: FromNativeSample,
A: FromNativeSample,
Create: Fn(Vec2<usize>, &RgbaChannels) -> Pixels,
Set: Fn(&mut Pixels, Vec2<usize>, (R, G, B, A)),
[src]
pub fn rgba_channels<R, G, B, A, Create, Set, Pixels>(
self,
create_pixels: Create,
set_pixel: Set
) -> CollectPixels<ReadOptionalChannel<ReadRequiredChannel<ReadRequiredChannel<ReadRequiredChannel<NoneMore, R>, G>, B>, A>, (R, G, B, A), Pixels, Create, Set> where
R: FromNativeSample,
G: FromNativeSample,
B: FromNativeSample,
A: FromNativeSample,
Create: Fn(Vec2<usize>, &RgbaChannels) -> Pixels,
Set: Fn(&mut Pixels, Vec2<usize>, (R, G, B, A)),
[src]Read only layers that contain rgba channels. Skips any other channels in the layer.
The alpha channel will contain the value 1.0
if no alpha channel can be found in the image.
Using two closures, define how to store the pixels.
The first closure creates an image, and the second closure inserts a single pixel.
The type of the pixel can be defined by the second closure;
it must be a tuple containing four values, each being either f16
, f32
, u32
or Sample
.
Throws an error for images with deep data or subsampling.
Use specific_channels
or all_channels
if you want to read something other than rgba.

self,
create_pixels: Create,

) -> CollectPixels<ReadRequiredChannel<ReadRequiredChannel<ReadRequiredChannel<NoneMore, R>, G>, B>, (R, G, B), Pixels, Create, Set> where

pub fn specific_channels(self) -> ReadZeroChannels
[src]
pub fn specific_channels(self) -> ReadZeroChannels
[src]Read only layers that contain the specified channels, skipping any other channels in the layer.
Further specify which channels should be included by calling .required("ChannelName")
or .optional("ChannelName", default_value)
on the result of this function.
Call collect_pixels
afterwards to define the pixel container for your set of channels.
Throws an error for images with deep data or subsampling.
