Owning Class: support
Requires: MathScript RT Module
a = fread_image(fname, ftype)
Reads image data from a file. The image size cannot exceed 4 megapixels.
|fname||Specifies the filename. fname is a string.|
|ftype||Specifies the file type. ftype is a string that accepts the following values.
|a||Returns the data LabVIEW reads from the file you specify in fname. a is a matrix of 64-bit, double-precision, floating-point numbers.|
If you use this function in a stand-alone application or shared library and fname is a relative path, LabVIEW searches for the file in the path where you installed the application or shared library. (Real-Time Module) If you deploy this function to an RT target and fname is a relative path, LabVIEW searches for the file in the path returned by the Default Data Directory VI.
The following table lists the support characteristics of this function.
|Supported in the LabVIEW Run-Time Engine||Yes|
|Supported on RT targets||Yes|
|Suitable for bounded execution times on RT||No (affects entire script)|
