我在使用zemax 2009的圖像仿真功能（image simulation）時(shí)，發(fā)現(xiàn)無法打開一個(gè)較大的文件（9207*5586） o1{3[=G  
手冊里說的是The name of the file for the source bitmap. The file may be in BMP, JPG, IMA, or BIM file formats. For a description of the IMA and BIM file formats see “The IMA format” on page161 and “The BIM format” on page162. The input files are stored in the \ImaFiles folder. IMA abd BIM files must have more than 1 but no more than 8,000 pixels in each direction, while JPG and BMP files must have more than 1 and no more than 16,000 pixels in each direction. JXt_
  
請問這是怎么回事呢？ IZ
