Back to ImageAdv Class Summary

Availability
Windows, Mac OSX, Linux

Usage
mdm.ImageAdv.convertToGrayscale():Boolean

Parameters
none

Returns
boolean that indicates if operation succeeded

Description
This method effectively removes all color information from 24/32bit color spaced bitmaps and saves only luminance information (8-bit). Please note that operation is destructive and cannot be reserved - but it operates on in-memory hosted copy of your originally loaded image data.

Notes
This operation does not change your original file. It operates on bitmap hosted in memory - so you have to flush changes to local file to persist them by saving JPEG/PNG files locally.

Example Code
if(image.isValid)
{
var converted:Boolean = image.convertToGrayscale();
if(converted)
{
image.savePng(outputPath);
};
};
