-Rendering vector graphics into pixel arrays can result in significant memory costs or loss of information, as demonstrated in Figure 1. Additionally, this process discards high-level structural information within the primitives, which is critical for recognition tasks such as identifying corners and contours.

 To summarize, we propose You Only Look at Text series (YOLaT & YOLaT++)  which addresses issues with raster graphics by taking in textual documents of vector graphics as input.

+YOLaT++ is introduced, characterized by a hierarchical structure designed for VGs, spanning three levels: **Primitive, Curve, and Point**. Additionally, YOLaT++ employs a position-aware enhancement strategy to effectively differentiate similar primitives.
