公共API和向後不相容的更改

這裡列出了Aspose.Words 19.2中引入的公共API更改。它不僅包括新的和過時的公共方法，還包括對Aspose.Words中幕後行為的任何變化的描述，這可能會影響現有程式碼。引入的任何行為都可以被可能修改現有行為，這一點尤為重要，並在此處進行了說明。

調整當儲存為PDF時，影象處理問題的警告資訊

WORDSNET-17338已經被解決

以前有一個通用警告文字“不支援的影象格式”。現在有一個針對OutOfMemoryException的特定警告，文字“沒有足夠的記憶體來載入影象”。以及帶有文字的通用警告“無法處理影象。可能不支援的影象格式”。

字型替換過程和公共API的更改

WORDSNET-14532現已解決：

字型提取和替換機制已更改

以前的字型提取過程是：

確切的字型名稱匹配
從文件中嵌入字型資料
為字型名稱指定的字型替換
FontInfo中的AltName（如果有）和AltName的替代
如果存在FontInfo並且設定了EnableFontSubstitution，則替換字型
DefaultFontName和DefaultFontName的替代
可用字型來源的任何字型
“Fanwood”字型嵌入到彙編中

現在字型提取過程是：

確切的字型名稱匹配
從文件中嵌入字型資料
FontInfo的AltName（如果有的話）
字型替換規則
- fontconfig替換
- 表替換字型名稱和alt名稱
- 字型資訊替換
- 預設字型替換
可用字型來源的任何字型
“Fanwood”字型嵌入到彙編中

為字型替換設定添加了新的公共API。與字型替換相關的之前的API方法/屬性已過時

刪除了不推薦使用的公共屬性TxtSaveOptions.ExportHeadersFooters

問題：WORDSNET-17560

刪除已棄用的公共屬性TxtSaveOptions.ExportHeadersFooters：

// Specifies whether to output headers and footers when exporting in plain text format.// Default value is true.public bool ExportHeadersFooters複製程式碼

請改用TxtSaveOptions.ExportHeadersFootersMode屬性。
