Struct ThumbnailWriter

pub struct ThumbnailWriter<'a, 'n: 'a> { /* private fields */ }

A self-contained thumbnail image.

Created by ThumbnailsWriter::add_thumbnail.

Implementations

impl<'a, 'n: 'a> ThumbnailWriter<'a, 'n>

pub fn format(&mut self, format: &str) -> &mut Self

Write the xmpGImg:format property with a custom format of the thumbnail image. Must be “JPEG” for now.

pub fn format_jpeg(&mut self) -> &mut Self

Write the xmpGImg:format property with the value “JPEG”.

pub fn width(&mut self, width: u64) -> &mut Self

Write the xmpGImg:width property.

pub fn height(&mut self, height: u64) -> &mut Self

Write the xmpGImg:height property.

pub fn image(&mut self, image: &str) -> &mut Self

Write the xmpGImg:image property.

The image must be a base64-encoded JPEG.

Methods from Deref<Target = Struct<'a, 'n>>

pub fn element( &mut self, name: &'a str, namespace: Namespace<'n>, ) -> Element<'_, 'n>

Start writing a property in the struct.

pub fn element_with_attrs<'b>( &mut self, name: &'a str, namespace: Namespace<'n>, attrs: impl IntoIterator<Item = (&'b str, &'b str)>, ) -> Element<'_, 'n>

Start writing a property with attributes in the struct.
