(an example is provided in the Appendix below).
|
||||||
|
|
||||||
|
"Derivative Works" shall mean any work, whether in Source or Object
|
||||||
|
form, that is based on (or derived from) the Work and for which the
|
||||||
|
editorial revisions, annotations, elaborations, or other modifications
|
||||||
|
represent, as a whole, an original work of authorship. For the purposes
|
||||||
|
of this License, Derivative Works shall not include works that remain
|
||||||
|
separable from, or merely link (or bind by name) to the interfaces of,
|
||||||
|
the Work and Derivative Works thereof.
|
||||||
|
|
||||||
|
"Contribution" shall mean any work of authorship, including
|
||||||
|
the original version of the Work and any modifications or additions
|
||||||
|
to that Work or Derivative Works thereof, that is intentionally
|
||||||
|
submitted to Licensor for inclusion in the Work by the copyright owner

Licensor for the purpose of discussing and improving the Work, but
|
||||||
|
excluding communication that is conspicuously marked or otherwise
|

|
designated in writing by the copyright owner as "Not a Contribution."
|
||||||
|
|
||||||
|
"Contributor" shall mean Licensor and any individual or Legal Entity

||||||
|
2. Grant of Copyright License. Subject to the terms and conditions of
|
||||||
|
this License, each Contributor hereby grants to You a perpetual,
|
||||||
|
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||||
|
copyright license to reproduce, prepare Derivative Works of,
|
||||||
|
publicly display, publicly perform, sublicense, and distribute the
|
||||||
|
Work and such Derivative Works in Source or Object form.
|
||||||
|
|
||||||
|
3. Grant of Patent License. Subject to the terms and conditions of
|
||||||
|
this License, each Contributor hereby grants to You a perpetual,
|
||||||
|
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||||
|
(except as stated in this section) patent license to make, have made,
|
||||||
|
use, offer to sell, sell, import, and otherwise transfer the Work,
|
||||||
|
where such license applies only to those patent claims licensable
|
||||||
|
by such Contributor that are necessarily infringed by their
|
||||||
|
Contribution(s) alone or by combination of their Contribution(s)
|
||||||
|
with the Work to which such Contribution(s) was submitted. If You
|
||||||
|
institute patent litigation against any entity (including a
|
||||||
|
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
||||||
|
or a Contribution incorporated within the Work constitutes direct
|
||||||
|
or contributory patent infringement, then any patent licenses
|
||||||
|
granted to You under this License for that Work shall terminate
|
||||||
|
as of the date such litigation is filed.
|
||||||
|
|
||||||
|
4. Redistribution. You may reproduce and distribute copies of the
|
||||||
|
Work or Derivative Works thereof in any medium, with or without
|
||||||
|
modifications, and in Source or Object form, provided that You
|
||||||
|
meet the following conditions:
|
||||||
|
|
||||||
|
(a) You must give any other recipients of the Work or
|
||||||
|
Derivative Works a copy of this License; and
|
||||||
|
|
||||||
|
(b) You must cause any modified files to carry prominent notices
|
||||||
|
stating that You changed the files; and
|
||||||
|
|
||||||
|
(c) You must retain, in the Source form of any Derivative Works
|
||||||
|
that You distribute, all copyright, patent, trademark, and
|
||||||
|
attribution notices from the Source form of the Work,
|
||||||
|
excluding those notices that do not pertain to any part of
|
||||||
|
the Derivative Works; and
|
||||||
|
|
||||||
|
(d) If the Work includes a "NOTICE" text file as part of its
|
||||||
|
distribution, then any Derivative Works that You distribute must
|
||||||
|
include a readable copy of the attribution notices contained
|
||||||
|
within such NOTICE file, excluding those notices that do not
|
||||||
|
pertain to any part of the Derivative Works, in at least one
|
||||||
|
of the following places: within a NOTICE text file distributed
|
||||||
|
as part of the Derivative Works; within the Source form or
|
||||||
|
documentation, if provided along with the Derivative Works; or,
|
||||||
|
within a display generated by the Derivative Works, if and
|
||||||
|
wherever such third-party notices normally appear. The contents
|
||||||
|
of the NOTICE file are for informational purposes only and
|
||||||
|
do not modify the License. You may add Your own attribution
|
||||||
|
notices within Derivative Works that You distribute, alongside
|
||||||
|
or as an addendum to the NOTICE text from the Work, provided
|
||||||
|
that such additional attribution notices cannot be construed
|
||||||
|
as modifying the License.
|
||||||
|
|
||||||
|
You may add Your own copyright statement to Your modifications and
|
||||||
|
may provide additional or different license terms and conditions
|
||||||
|
for use, reproduction, or distribution of Your modifications, or
|
||||||
|
for any such Derivative Works as a whole, provided Your use,
|
||||||
|
reproduction, and distribution of the Work otherwise complies with
|
||||||
|
the conditions stated in this License.
|
||||||
|
|
||||||
|
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||||
|
any Contribution intentionally submitted for inclusion in the Work
|
||||||
|
by You to the Licensor shall be under the terms and conditions of
|
||||||
|
this License, without any additional terms or conditions.
|
||||||
|
Notwithstanding the above, nothing herein shall supersede or modify
|
||||||
|
the terms of any separate license agreement you may have executed
|
||||||
|
with Licensor regarding such Contributions.
|
||||||
|
|
||||||
|
6. Trademarks. This License does not grant permission to use the trade
|
||||||
|
names, trademarks, service marks, or product names of the Licensor,
|
||||||
|
except as required for reasonable and customary use in describing the
|
||||||
|
origin of the Work and reproducing the content of the NOTICE file.
|
||||||
|
|
||||||
|
7. Disclaimer of Warranty. Unless required by applicable law or
|
||||||
|
agreed to in writing, Licensor provides the Work (and each
|
||||||
|
Contributor provides its Contributions) on an "AS IS" BASIS,
|
||||||
|
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
||||||
|
implied, including, without limitation, any warranties or conditions
|
||||||
|
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
||||||
|
PARTICULAR PURPOSE. You are solely responsible for determining the
|
||||||
|
appropriateness of using or redistributing the Work and assume any
|
||||||
|
risks associated with Your exercise of permissions under this License.
|
||||||
|
|
||||||
|
8. Limitation of Liability. In no event and under no legal theory,
|
||||||
|
whether in tort (including negligence), contract, or otherwise,
|
||||||
|
unless required by applicable law (such as deliberate and grossly
|
||||||
|
negligent acts) or agreed to in writing, shall any Contributor be
|
||||||
|
liable to You for damages, including any direct, indirect, special,
|
||||||
|
incidental, or consequential damages of any character arising as a
|
||||||
|
result of this License or out of the use or inability to use the
|
||||||
|
Work (including but not limited to damages for loss of goodwill,
|
||||||
|
work stoppage, computer failure or malfunction, or any and all
|
||||||
|
other commercial damages or losses), even if such Contributor
|
||||||
|
has been advised of the possibility of such damages.
|
||||||
|
|
||||||
|
9. Accepting Warranty or Additional Liability. While redistributing
|
||||||
|
the Work or Derivative Works thereof, You may choose to offer,
|
||||||
|
and charge a fee for, acceptance of support, warranty, indemnity,
|
||||||
|
or other liability obligations and/or rights consistent with this
|
||||||
|
License. However, in accepting such obligations, You may act only
|
||||||
|
on Your own behalf and on Your sole responsibility, not on behalf
|
||||||
|
of any other Contributor, and only if You agree to indemnify,
|
||||||
|
defend, and hold each Contributor harmless for any liability
|
||||||
|
incurred by, or claims asserted against, such Contributor by reason
|
||||||
|
of your accepting any such warranty or additional liability.
|
||||||
|
|
||||||

#### 软件架构
|
## 简介
|
||||||
软件架构说明
|
|
||||||
|
- 支持内存缓存，使用LRUCache算法，对图片数据进行内存缓存
|
||||||
|
- 支持磁盘缓存，对于下载图片会保存一份至磁盘当中。
|
||||||
|
- 支持进行图片变换。
|
||||||
|
- 支持用户配置参数使用:(例如：配置是否开启第一级内存缓存，配置磁盘缓存策略，配置仅使用缓存加载数据，配置图片变换效果，配置占位图，配置加载失败占位图等)。
|
||||||
|
- 推荐使用GlideImage组件配合GlideOption参数来实现功能
|
||||||
|
- 支持用户自定义配置实现能力参考GlideImage组件中对于入参GlideOption的处理
|
||||||
|

|
||||||

.width('100%')
|
||||||
|

|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
#### 自定义实现：
|
||||||
|
|
||||||
|
使用原生Image组件，配合用户配置参数实现。
|
||||||
|
|
||||||
|
##### 步骤1：
|
||||||
|
|
||||||
|
定义一个入参 PixelMap
|
||||||
|
|
||||||
|
```typescript
|
||||||
|
@State tomatoPixelMap:PixelMap = new PixelMap();
|
||||||
|
width:number = 200;
|
||||||
|
height:number = 200;
|
||||||
|
```
|
||||||
|
|
||||||
|
##### 步骤2：
|
||||||
|
|
||||||
|
在你的component组件中，写下一个Image组件，将基础参数（入参PixelMap，组件的宽、高）配置好
|
||||||
|
|
||||||
|
```
|
||||||
|
Image(this.tomatoPixelMap)
|
||||||
|
.backgroundColor(Color.Grey)
|
||||||
|
.objectFit(ImageFit.Contain)
|
||||||
|
.width(this.width)
|
||||||
|
.height(this.height)
|
||||||
|
```
|
||||||
|
|
||||||
|
##### 步骤3：
|
||||||
|
|
||||||
|
在aboutToAppear() 函数中调用加载流程
|
||||||
|
|
||||||
|
```typescript
|
||||||
|
//配置参数
|
||||||
|
let requestOptin = new RequestOption();
|
||||||
|
//加载本地图片
|
||||||
|
requestOptin.load($r('app.media.IceCream'))
|
||||||
|
.addListener((err,data) => {
|
||||||
|
//加载成功/失败回调监听
|
||||||
|
})
|
||||||
|
.placeholder( $r('app.media.icon_loading'), (data)=>{
|
||||||
|
// 占位图回调监听
|
||||||
|
})
|
||||||
|
.errorholder(this.glideOption.errorholderSrc, (data)=>{
|
||||||
|
// 失败占位图回调监听
|
||||||
|
})
|
||||||
|
.thumbnail(this.glideOption.thumbSizeMultiplier, (data) => {
|
||||||
|
// 缩略图加载成功回调
|
||||||
|
})
|
||||||
|
// 一定要把控件大小传给RequestOption,图片变换必须
|
||||||
|
.setImageViewSize({width:this.width, height:this.height})
|
||||||
|
// 设置缓存策略
|
||||||
|
.diskCacheStrategy(new Strategy())
|
||||||
|
.addProgressListener((percentValue: string) => {
|
||||||
|
// 图片网络加载进度条百分比回调
|
||||||
|
})
|
||||||
|
.addRetryListener((error: any) => {
|
||||||
|
// 加载失败重试监听 图片加载失败时优先展示重试图层，点击重试图层，会重新进行一次加载流程
|
||||||
|
})
|
||||||
|
.transforms(new RoundedCornersTransformation({top:10}))
|
||||||
|
// 启动加载流程，执行结果将会返回到上面的回调接口中
|
||||||
|
Glide.call(requestOptin);
|
||||||
|
```
|
||||||
|
|
||||||
|
##### 步骤4：
|
||||||
|
|
||||||
|

* 以24位色图像为例子，每种色彩都可以用0-255，

|
* 一共256种深度来表示。如果我们把它画在一个二维坐标上，
|
||||||
|
* 正好是一条直线。比如我们将像素的色深作为横坐标，输出色深作为纵坐标的画，正好是一条经过原点(0，0)的45度斜线
|
||||||
|
* 那么很容易就可以写出它的直线方程：Out = In * 1 ，系数1就是对比度的概念.如果把条直线加上一个偏移量变成B，那么它的直线方程就成为：
|
||||||
|
* Out = In * 1 + (ab)偏移量(ab)就是亮度的增量。
|
||||||
|
*只要有初中的代数知识就很容易看出它满足一条直线方程：Y= A * X + B。但是，我们这里要处理的情况稍微有些不同，在图像处理中，对比度和亮度要分别对待。不能因为改变而改变亮度，因为我们习惯上把灰色(127，127)这一点作为中心点。
|
||||||
|
*
|
||||||
|
*直线公式修改成：Y=( X - 127 ) * A + B。A表示对比度，B表示亮度增量。
|
||||||
|
* 只要亮度增量 B＝0，无论怎么改变对比度 A，该直线始终通过中心点(127,127),也就是说改变对比度的同时，亮度没有改变

// This is a compromise between Gaussian Blur and Box blur
|

// It creates much better looking blurs than Box Blur, but is
|
||||||
|
// 7x faster than my Gaussian Blur implementation.
|

|
//
|
||||||
|
// I called it Stack Blur because this describes best how this
|
||||||
|
// filter works internally: it creates a kind of moving stack
|
||||||
|
// of colors whilst scanning through the image. Thereby it
|
||||||
|
// just has to add one new block of color to the right side
|
||||||
|
// of the stack and remove the leftmost color. The remaining
|
||||||
|
// colors on the topmost layer of the stack are either added on
|
||||||
|
// or reduced by one, depending on if they are on the right or
|
||||||
|
// on the left side of the stack.
