PYTHON - Load random images from a folder without knowing the file name.

KeirMeDear

I'm wanting to make a system where one sketch creates an image and sends it into a folder where a second sketch randomly selects and loads one of the images in the folder. I know how to load images but how would I do it without knowing the file name.

(I'm also coding in python not js)

• Processing got an undocumented function called listPaths().
• For its 1st parameter, we pass the path of the target folder as a String.
• For its 2nd parameter we can pass 1 String w/ all the desired extensions.
• Then it returns a String[] array of all paths from that folder path fully filtered out.
• However, given its undocumented, in order to access it under Python Mode, we need to prefix it w/ this.. :-<
• Here's a wrapper function for listPaths() I did, w/ all Processing's valid image extensions defined there already: \m/

def getPathsFromFolder(folder, EXTS='extensions=,png,jpg,jpeg,gif,tif,tiff,tga,bmp'):
    return this.listPaths(folder, EXTS);

Usage example: :-B

def setup():
    global imagePaths
    imagePaths = getPathsFromFolder(this.dataPath(''))

Replace the argument this.dataPath('') w/ the String folder path where your images are. O:-)
