img_as_uintConvert to 16-bit uint. img_as_intConvert to 16-bit int. 二、颜色空间及其转换 如前所述,除了直接转换可以改变数据类型外,还可以通过图像的颜色空间转换来改变数据类型。 常用的颜色空间有灰度空间、rgb空间、hsv空间和cmyk空间。颜色空间转换以后,图片类型都变成了float型。

3.Convert.ToInt32() 、 int 、 int.Parse() 、int.TryParse 的区别 1.对于转换对象 int:只能是数字类型(float,int,uint等),但不能是字符串。 int.TryParse() 和 int.Parse():只能是整型字符串(即各种整型 ToString() 之后的形式)不能为浮点型字符串,否则 int.Parse() 就会出现输入的字符串格式不正确...
