# Example

## Show an common image format

```shell
icu show res/img_0.png
```

You will get a window with the image.

## Show an LVGL image format

* You don't need to specify the input format, because ICU can detect it automatically. *

```shell
icu show res/img_0.bin
```

And you will get a window with the image like before.

## Convert an common image format to an common image format

if you want to converting images with logs out put, you can use `-vv` option.

```shell
$ icu -vv convert res/img_0.png res/img_0.jpeg --output-format webp`

[2024-02-29T13:05:06Z INFO  icu] Start converting files

[2024-02-29T13:05:06Z INFO  icu] took 0.002257s for converting [res/img_0.jpeg] to [res/img_0.webp] with format [WEBP]

```

or in a short form:

```shell
$ icu -vv convert res/img_0.png res/img_0.jpeg -F webp
```

## Convert some images in a folder to another specific folder

convert all images in the `res` folder to jpeg format and save them in the `res/output` folder, if the output file
already exists, it will override it (you should use `-r --override-output` option).

*if and the output folder will keep the same structure as the input folder*.

```shell
$ icu convert res -O res/output --output-format jpeg --override-output
```

or in a short form:

```shell
$ icu convert res -O res/output -F jpeg -r
```

## Convert an LVGL image format to an common image format

Convert an LVGL image format to an common image format.
And if you specify the `--overide-output` option, ICU will override the output file if it already exists.
And you will get a warning message for sure if the output file already exists.

```shell
$ icu -vv convert res/img_0.bin -O res/output -F jpeg -r

[2024-03-03T16:08:01Z INFO  icu] Start converting file
[2024-03-03T16:08:01Z INFO  icu] 
[2024-03-03T16:08:01Z WARN  icu] Override output file <res/output/img_0.jpeg> for converting <res/img_0.bin>

[2024-03-03T16:08:01Z INFO  icu]

```

## Convert an common image format to an LVGL image format

Convert an common image format to an LVGL image format, you need to specify the output color format and lvgl version.
But if you don't specify the lvgl version, ICU will use the default version (v9).

```shell
$ icu convert res/img_0.png -O res/output -F lvgl -C i8 -r
```

## Convert an common image format to an LVGL image format with stride align

Convert an common image format to an LVGL image format with stride align, you need to specify the output color format,
lvgl version, and stride align (default is 1).

***4** means the stride of the output image will be 4 bytes aligned.*

```shell
$ icu convert res/img_0.png -O res/output -F lvgl -C i8 -S 4 -r
```
