Text combing not working

user26 · November 17, 2021, 5:23pm

I found where PDF.js handles it:

mozilla/pdf.js/blob/3209c013c411ace4414246a153eac26eea640aba/src/display/annotation_layer.js#L1112

    
      
            }
          
          
  if (blurListener) {
              element.addEventListener("blur", blurListener);
            }
          
          
  if (this.data.maxLen !== null) {
              element.maxLength = this.data.maxLen;
            }
          
          
  if (this.data.comb) {
              const fieldWidth = this.data.rect[2] - this.data.rect[0];
              const combWidth = fieldWidth / this.data.maxLen;
          
          
    element.classList.add("comb");
              element.style.letterSpacing = `calc(${combWidth}px - 1ch)`;
            }
          } else {
            element = document.createElement("div");
            element.textContent = this.data.fieldValue;
            element.style.verticalAlign = "middle";
