File › Place and File › Open read PSD and PSB files: the merged image every such document carries after its layers, which is what a linked PSD shows. A placed PSD links like any image, so the Links panel updates and relinks it, and it is sized by its ResolutionInfo resource. The reader is written from the public file format specification. It reads Bitmap, Grayscale, Duotone, Indexed, RGB, CMYK (through the colour settings' CMYK) and Lab, at 1, 8, 16 and 32 bits per channel (32-bit values are linear), raw, PackBits or zipped with or without prediction. A document with transparency stores its merged image on white with the alpha in the first extra channel. It comes back with straight colours, also for 16- and 32-bit files, which say so in their Lr16/Lr32 block. Multichannel files are refused with a message. The file is untrusted: every read is bounds-checked and the image's size is checked against the decode budget before anything is allocated. PSB is a read-only format of its own, so exports never write a PSD under a .psb name. The desktop packaging still doesn't associate either extension with VectorCraft (UNASSOCIATED_EXTS): they belong to raster editors. Layers (import options) are left for later.
