Syntax
Examining an external file Hide the details
<Result> = fIsImage(<File name and path>)
<Result>: Boolean - True if the file is an image that can be loaded by WINDEV, WEBDEV or WINDEV Mobile,
- False otherwise.
<File name and path>: Ansi or Unicode character string Name and full (or relative) path of the file to identify. A UNC path can be used.
Analyzing a Buffer variable Hide the details
<Result> = fIsImage(<Variable name>)
<Result>: Boolean - True if the buffer corresponds to an image,
- False otherwise.
<Variable name>: Buffer or Binary Memo variable Name of the Buffer or Binary Memo variable containing the image to be analyzed. Remarks fIsImage can be quite slow because it tries to load the image. To quickly check whether a file is an image, you also have the ability to check the file extension directly.
