小像素字體

Question

我正在嘗試在顯示器上顯示像素，準備在一組LED上顯示時。 我正在使用字體繪製位圖，然後讀取位圖，無論像素是較亮還是較暗，並將其放入布爾值的二維數組中。 然後將此數組傳遞到特定於接口的顯示方法中進行顯示。 由於這套設備只有6個像素高，我使用的字體是從www.dafont.com/6px.font獲得6像素分辨率。 目前這個系統不能很好地顯示 - 有些字符不是真正可讀。

這是甚至正確的方法嗎？我該怎麼做？ 謝謝！

任何幫助深表感謝 - 感謝！

找出問題 - 字體甚至沒有分配！我調用 regFont = new Font（familyName，6，FontStyle.Regular，GraphicsUnit.Pixel）;

它沒有改變！就像，如果你在調試器中通過了，賦值後值不會改變。太奇怪了。但是當我改變InitFont方法說：

void InitFont() 
    { 
     System.Drawing.Text.PrivateFontCollection privateFontCollection = 
      new System.Drawing.Text.PrivateFontCollection(); 
     privateFontCollection.AddFontFile("../../6px-Normal.ttf"); 
     solidBrush = new SolidBrush(Color.Black); 
     FontFamily[] fontFamilies = privateFontCollection.Families; 
     regFont = new Font(fontFamilies[0], 6); 
    } 

分配工作。 所以有點反高潮，但謝謝你們的幫助。
