Method RenderToMaxDimension

Namespace
LMKit.Data
Assembly
LM-Kit.NET.dll

RenderToMaxDimension(int, int)

Renders a page so its LONGEST side is exactly maxDimension pixels, preserving the page's aspect ratio; the shorter side follows. Every rendered page therefore shares one max-dimension box regardless of orientation or native canvas size - ideal for uniform thumbnails and previews.

public ImageBuffer RenderToMaxDimension(int maxDimension, int pageIndex = 0)

Parameters

maxDimension int

Target size in pixels of the longer side (clamped to at least 1).

pageIndex int

Zero-based page index. Default is 0 (first page).

Returns

ImageBuffer

A new ImageBuffer sized to the max-dimension box.

Examples

using var attachment = new Attachment("slides.pdf");
using ImageBuffer thumb = attachment.RenderToMaxDimension(maxDimension: 800, pageIndex: 0);
byte[] webp = thumb.SaveAsWebpBytes(quality: 90);

Remarks

For paginated documents that rasterize (e.g. PDF) the page is drawn straight to the target pixel box, so the output is exactly sized and vector-crisp - there is no zoom/DPI round-trip. For raster images the native frame is fit DOWN into the box and never upscaled (enlarging a raster only invents blur).

The returned ImageBuffer must be disposed by the caller.
