Alias Pix Image
- Description
- BOF, offset 4: 0x0000 (representing offset to x coordinates from end of 10 byte header), {2}, 0x0018 representing 24 bits per pixel, [!00] representing number of contiguous bytes (greater than 0) that contain the following 3 byte RGB value - https://www.autodesk.com/techpubs/aliasstudio/2010/index.html?url=WS73099cc142f4875535a241551166ac8792f-7d76.htm,topicNumber=d0e246178
- Provenance
- For now we set Java Class file at a greater priority due to a small chance of clashes. It may be desirable to further strengthen this signature, however since bytes 1-4 represent x and y lengths, valid values for each could be anything from 0001-FFFF, and since a pix image could theoretically be 1x1 pixel in size, the whole of the image (following the header) could be, e.g. 01000000
