pub struct ImageDisplay { /* private fields */ }

Displays images in the terminal with ASCII fallback support.

Provides terminal rendering of images with:

• Metadata display (format, size, dimensions)
• ASCII placeholder for unsupported terminals
• Automatic resizing to fit terminal bounds (max 80x30)
• Multi-image support with vertical organization

pub fn render_image(&self, metadata: &ImageMetadata) -> ImageResult<String>

Render a single image with metadata.

Arguments

• metadata - Image metadata containing format, size, dimensions

Returns

Rendered image string with metadata

pub fn calculate_resized_dimensions( &self, original_width: u32, original_height: u32, ) -> (u32, u32)

Calculate resized dimensions to fit within terminal bounds.

Arguments

• original_width - Original image width in pixels
• original_height - Original image height in pixels

Returns

Resized dimensions (width, height) in characters

pub fn verify_metadata_present( &self, display_output: &str, metadata: &ImageMetadata, ) -> ImageResult<bool>

Verify that display includes all required metadata.

Arguments

• display_output - The rendered display string
• metadata - The image metadata

Returns

True if all metadata is present, error otherwise

pub fn verify_fits_in_terminal(&self, display_output: &str) -> ImageResult<bool>

Verify that display fits within terminal bounds.

Arguments

• display_output - The rendered display string

Returns

True if display fits within bounds, error otherwise

pub fn render_multiple_images( &self, metadata_list: &[ImageMetadata], ) -> ImageResult<String>

Render multiple images organized vertically with separators.

Arguments

• metadata_list - List of image metadata to render

Returns

Rendered multi-image display string

pub fn verify_multiple_images_organized( &self, display_output: &str, metadata_list: &[ImageMetadata], ) -> ImageResult<bool>

Verify that multiple images are organized vertically.

Arguments

• display_output - The rendered display string
• metadata_list - List of image metadata

Returns

True if images are properly organized, error otherwise
