StitchPagesSideBySide
Page manipulation
Description
Places two existing pages next to each other on a new, wider page. Both source pages are captured into vector Form XObjects and drawn left and right, scaled to the requested TargetHeight while preserving their individual aspect ratios. A Gap is inserted between them.
The new page is appended to the document; both source pages are captured and hidden. The new page's width is automatically computed as Page1ScaledWidth + Gap + Page2ScaledWidth.
