[ISSUE-005]: Alpha Mask channel not processed correctly
Description
When processing source images that contain an alpha channel intended for use as a MASK map, the tool's output for the MASK map is an RGBA image instead of a grayscale image derived solely from the alpha channel.
Current Behavior
If a source image (e.g., a PNG or TIF) has an alpha channel and is classified as a MASK map type, the resulting output MASK file retains the RGB channels (potentially with incorrect data or black/white values) in addition to the alpha channel, resulting in an RGBA output image.
Desired Behavior / Goals
When processing a source image with an alpha channel for a MASK map type, the tool should extract only the alpha channel data and output a single-channel (grayscale) image representing the mask. The RGB channels from the source should be discarded for the MASK output.
Implementation Notes (Optional)
(This requires modifying the image processing logic for MASK map types to specifically isolate and save only the alpha channel as a grayscale image. Need to check the relevant sections in asset_processor.py related to map processing and saving.)
Acceptance Criteria (Optional)
- Process an asset containing a source image with an alpha channel intended as a MASK map.
- Verify that the output MASK file is a grayscale image (single channel) and accurately represents the alpha channel data from the source.
- Verify that the output MASK file does not contain redundant or incorrect RGB channel data.
