What it does

ImageToolbox is a powerful app for advanced image manipulation, offering dozens of features including crop, draw, filters, OCR, and image processing options.

When to use it

•When you need to automate image processing tasks, such as resizing or watermarking images
•When you want to apply filters or effects to images, such as converting to grayscale or sepia tone
•When you need to extract text from images using OCR (Optical Character Recognition) technology

Ready-to-paste prompt

Apply a sepia tone filter to an image using the `applyFilter()` method: `ImageToolbox.applyFilter(imagePath, Filter.SEPIA)`

Heads up: Make sure you have the necessary Android SDK version installed, as ImageToolbox requires a minimum SDK version of 21 (Android 5.0)
