# Changelog
# 4.4.0
* `TextViewSpan` to obtain `TextView` in which markdown is displayed (applied by `CorePlugin`)
* `TextLayoutSpan` to obtain `Layout` in which markdown is displayed (applied by `TablePlugin`, more specifically `TableRowSpan` to propagate layout in which cell content is displayed)
* `HtmlEmptyTagReplacement` now is configurable by `HtmlPlugin`, `iframe` handling ([#235])
* `AsyncDrawable` now uses `TextView` width without padding instead of width of canvas
* Support for images inside table cells (`ext-tables` module)
* Expose `enabledBlockTypes` in `CorePlugin`
* Update `jlatexmath-android` dependency ([#225])
* Update `image-coil` module (Coil version `0.10.1`) ([#244])<br>Thanks to [@tylerbwong]
* Rename `UrlProcessor` to `ImageDestinationProcessor` (`io.noties.markwon.urlprocessor` -&gt; `io.noties.markwon.image.destination`) and limit its usage to process **only** destination URL of images (was used to also process links before)
* `fallbackToRawInputWhenEmpty` `Markwon.Builder` configuration to fallback to raw input if rendered markdown is empty ([#242])

# 4.3.1
* Fix DexGuard optimization issue ([#216])<br>Thanks [@francescocervone]
* module `images`: `GifSupport` and `SvgSupport` use `Class.forName` instead access to full qualified class name

## UrlProcessor

Process URLs in your markdown (for links and images). If not provided explicitly,
Process destinations (URLs) of images in your markdown. If not provided explicitly,
default **no-op** implementation will be used, which does not modify URLs (keeping them as-is).
`Markwon` provides 2 implementations of `UrlProcessor`:
* `UrlProcessorRelativeToAbsolute`
* `UrlProcessorAndroidAssets`
* `ImageDestinationProcessorRelativeToAbsolute`
* `ImageDestinationProcessorAssets`
### UrlProcessorRelativeToAbsolute
### ImageDestinationProcessorRelativeToAbsolute
`UrlProcessorRelativeToAbsolute` can be used to make relative URL absolute. For example if an image is
defined like this: `![img](./art/image.JPG)` and `UrlProcessorRelativeToAbsolute`
`ImageDestinationProcessorRelativeToAbsolute` can be used to make relative URL absolute. For example if an image is
defined like this: `![img](./art/image.JPG)` and `ImageDestinationProcessorRelativeToAbsolute`
is created with `https://github.com/noties/Markwon/raw/master/` as the base:
`new UrlProcessorRelativeToAbsolute("https://github.com/noties/Markwon/raw/master/")`,
`new ImageDestinationProcessorRelativeToAbsolute("https://github.com/noties/Markwon/raw/master/")`,
then final image will have `https://github.com/noties/Markwon/raw/master/art/image.JPG`
as the destination.
### UrlProcessorAndroidAssets
### ImageDestinationProcessorAssets
`UrlProcessorAndroidAssets` can be used to make processed links to point to Android assets folder.
`ImageDestinationProcessorAssets` can be used to make processed destinations to point to Android assets folder.
So an image: `![img](./art/image.JPG)` will have `file:///android_asset/art/image.JPG` as the
destination.
:::tip
Please note that `UrlProcessorAndroidAssets` will process only URLs that have no `scheme` information,
Please note that `ImageDestinationProcessorAssets` will process only URLs that have no `scheme` information,
so a `./art/image.png` will become `file:///android_asset/art/image.JPG` whilst `https://so.me/where.png`
