12 Photoshop writes its own format of meta information called a Photoshop
13 IRB resource which is located in the APP13 record of JPEG files. This
14 module contains the definitions to read this information.
15
17 Photoshop IRB blocks may have an associated resource name. These names
18 are usually just an empty string, but if not empty they are displayed
19 in the verbose level 2 (or greater) output. A special
20 "SetResourceName" flag may be set to '1' in the tag information hash to
21 cause the resource name to be appended to the value when extracted. If
22 this is done, the returned value has the form "VALUE/#NAME#/". When
23 writing, the writer routine looks for this syntax (if "SetResourceName"
24 is defined), and and uses the embedded name to set the name of the new
25 resource. This allows the resource names to be preserved when copying
26 Photoshop information via user-defined tags.
