Trait VipsBuffer 

pub trait VipsBuffer {
    // Required method
    fn thumbnail(&self, width: u32, height: u32) -> Result<VipsImage<'_>>;
}

Extension trait for thumbnailing from a byte buffer

Example

use vips::*;

fn main() -> Result<()> {
    let _instance = VipsInstance::new("app_test", true)?;
    let binding = std::fs::read("./examples/images/kodim01.png")?;
    let img_data: &[u8] = binding.as_slice();
    let thumbnail = img_data.thumbnail(100, 100)?;
    thumbnail.write_to_file("kodim01_thumb.png")?;
    Ok(())
}

Required Methods

fn thumbnail(&self, width: u32, height: u32) -> Result<VipsImage<'_>>

Implementations on Foreign Types

impl VipsBuffer for &[u8]

fn thumbnail(&self, width: u32, height: u32) -> Result<VipsImage<'_>>

Create a thumbnail VipsImage from the byte buffer

Arguments

• width - The desired thumbnail width
• height - The desired thumbnail height

Errors

Returns an error if the thumbnail creation fails

Example

use vips::*;

fn main() -> Result<()> {
    let _instance = VipsInstance::new("app_test", true)?;
    let binding = std::fs::read("./examples/images/kodim01.png")?;
    let img_data: &[u8] = binding.as_slice();
    let thumbnail = img_data.thumbnail(100, 100)?;
    thumbnail.write_to_file("kodim01_thumb.png")?;
    Ok(())
}

Safety Note

The input byte slice must contain valid image data that libvips can decode. Providing invalid or corrupted data may lead to undefined behavior. Ensure that the data is properly validated before calling this method.
