Font appears broken and low-quality when zooming out #294

Open hooyuser opened 4 months ago

hooyuser commented 4 months ago

Describe the bug Hello, I am experiencing an issue with the preview plugin where the font quality significantly degrades when I zoom out. There is noticeable aliasing phenomenon (like the common downsampling aliasing) that causes the font to be distorted.

Capture_lowres_preview typst-preview extension

For example, the top half of the letter “t” becomes disconnected. Please refer to the attached image below that compares this with the rendering result from a PDF renderer under a similar zoom level.

Capture_lowres_pdf pdf renderer

It’s evident that the PDF renderer produces a clearer and more recognizable output.

When zooming in, however, the font rendering is quite clear. The attached images below show the rendering effects from both the PDF renderer and the typst-preview.

Could you please look into this issue? Thank you!
