Pixel decoding and image re-encoding: how DDS becomes PSD

Directdraw surface texture data that can include block compression, mipmaps, cubemap faces, and alpha is decoded into a working pixel canvas first, then written back out under PSD's own color and compression model. Dimensions can stay exactly the same even as encoding, metadata, and fine detail change underneath. DDS loading inventories texture format, block compression, dimensions, mip levels, array slices, cubemap faces, alpha, and channel conventions before selecting one surface. PSD output aims to retain a Photoshop-style composite and editable layers, masks, channels, effects, text, and color data instead of only one flattened bitmap.

The delivery decision for this DDS to PSD route

PSD wins this route whenever its specific mix of compatibility, alpha, animation, and file size fits the destination better than DDS does.

What changes between the DDS model and the PSD deliverable

PSD supports alpha transparency that DDS never had, so any transparent areas in the result are newly created, not carried over from the source.
PSD supports an editable object model DDS never had, so structure in the result is newly assigned by the writer, not carried over from the source.
Metadata handling differs between DDS and PSD; do not assume every application-specific field carries across untouched.

What the DDS source carries and the PSD output demands

DDS

What can fail when DDS raster image is interpreted

A flat image export may keep only the top mip level or one face and can mishandle normal-map channels.

PSD

What PSD raster image cannot safely promise

Most non-PSD outputs flatten layers, while unsupported smart objects or effects may render differently.

ENGINE

How the PSD writer handles this route

a Photoshop document that can contain layers, masks, channels, type, and adjustment data is what gets written, labeled as image/vnd.adobe.photoshop. Whether that actually opens depends on the receiving application, not on the file extension.

Acceptance evidence for the converted PSD

BEFORE

Record the DDS evidence before conversion

Inspect alpha, channel order, every required cubemap face, mip level, and texture orientation in the target engine.

AFTER

Test the PSD file in its receiving workflow

Open the result in the intended editor and inspect layer count, masks, typography, blend modes, and canvas size.
