dim() 是“dimension”的缩写,用于计算组合类型(可以是列表、矩阵和字符串)的维数。对于列表,它会返回元素总数。对于字符串,它会返回字数。对于矩阵,它会返回一个二维列表,分别是它的行数和列数。 count() 是单纯计数元素个数的函数,属于比较迷惑的黑魔法,建议大家自己尝试一下。它接受的参数可以是函数或程序以外...

A zero-length array is declared with a dimension of -1. For example:VB Copy Dim arrZ(-1) As String You might need to create a zero-length array under the following circumstances:Without risking a NullReferenceException exception, your code must access members of the Array class, such as...
For example, the fol- lowing type of declaration is not supported: Dim MyString As String * 32 Instead, you can dimension the string as a fixed-length array of characters, as follows: Dim MyString(32) As Char Or you can use a special class, VBFixedLengthString, defined in the Visual ...
It is not entirely clear how the dimension conditioning influences the composition. By preliminary testing it seems that settingwidth/heightandtarget_width/heightto 4096 tends to generate slightly sharper details. To keep the correct aspect ratio at more extreme image resolution it might be a good ...
