Major Features

PSD/PSB Support on .NET 6: Added support for converting from PSD and PSB formats when targeting .NET 6.
Advanced PDF Scaling Modes: Introduced new page scaling options for PDF output: ScaleToFit, ScaleToWidth, ScaleToHeight, and ScaleToFill, providing greater control over layout resizing.
Key Bug Fixes: Addressed conversion issues involving AI, PSD, PSB, email attachments, and spreadsheets. Fixed layout misalignment during PDF resizing, resolved MOBI-to-XPS corruption, and optimized resource usage for DWG-to-PDF conversion.

Public API and backward incompatible changes

Introduced ResizeMode property in the PdfConvertOptions class. It offers five different scaling strategies:

AlignTopLeft - No scaling, aligns content to top-left corner (default behavior)
ScaleToFit - Proportionally scales content to fit within new dimensions without overflow
ScaleToWidth - Scales content to match page width, maintaining aspect ratio
ScaleToHeight - Scales content to match page height, maintaining aspect ratio

ScaleToFill - Stretches content to fill entire page (may distort aspect ratio)

using (Converter converter = new Converter("sample.pdf"))
{
    PdfConvertOptions options = new PdfConvertOptions();
    options.ResizeMode = PageResizeMode.ScaleToFit // Proportional scaling
    options.SizeSettings.PageSize = PageSize.A4;
    converter.Convert("converted.pdf", options);
}
