Description

Decodes a PSD image to a mapping, defined as follows.

"channels" : int(1..24) The number of channels in the image, including any alpha channels. "height" : int(1..30000) The image dimensions. "width" : int(1..30000) "compression" : int(0..1) 1 if the image is compressed, 0 if not. "depth" : int(1..1)|int(8..8)|int(16..16) The number of bits per channel. "mode" : int(0..4)|int(7..9) The color mode of the file. 0 Bitmap 1 Greyscale 2 Indexed 3 RGB 4 CMYK 7 Multichannel 8 Duotone 9 Lab "color_data" : string Raw color data. "image_data" : string Ram image data. "resources" : mapping(string|int:mixed) Additional image data. Se mappping below. "layers" : array(mapping) An array with the layers of the image. See mapping below.

The resources mapping. Unknown resources will be identified by their ID number (as an int).

"caption" : string Image caption. "url" : string Image associated URL. "active_layer" : int Which layer is active. "guides" : array(mapping(string:int)) An array with all guides stored in the image file. "pos" : int The position of the guide. "vertical" : int(0..1) 1 if the guide is vertical, 0 if it is horizontal. "resinof" : mapping(string:int) Resolution information "hres" : int FIXME: Document these. "hres_unit" : int "width_unit" : int "vres" : int "vres_unit" : int "height_unit" : int

The layer mapping:

"top" : int The rectangle containing the contents of the layer. "left" : int "right" : int "bottom" : int "mask_top" : int FIXME: Document these "mask_left" : int "mask_right" : int "mask_bottom" : int "mask_flags" : int "opacity" : int(0..255) 0=transparent, 255=opaque. "clipping" : int 0=base, 1=non-base. "flags" : int bit 0=transparency protected bit 1=visible "mode" : string Blend mode. "norm" Normal "dark" Darken "lite" Lighten "hue " Hue "sat " Saturation "colr" Color "lum " Luminosity "mul " Multiply "scrn" Screen "diss" Dissolve "over" Overlay "hLit" Hard light "sLit" Soft light "diff" Difference "extra_data" : string Raw extra data. "name" : string The name of the layer "channels" : array(mapping(string:int|string)) The channels of the layer. Each array element is a mapping as follows "id" : int The ID of the channel -2 User supplied layer mask -1 Transparency mask 0 Red 1 Green 2 Blue "data" : string The image data
