File Structure GDL documents contain the information for GDL to produce a label. A label is composed of three TextEdit records, a palette, and an optional picture. This information is in the data fork. The resource fork is reserved and should not be used. The File Format The data fork of GDL files contains the following data: PicFlag (+000) Boolean Long If this flag is TRUE, the next 5600 bytes contain a bit-mapped image of the graphic for this label. If this flag is FALSE, the next field is not present. BitMap (+004) 5600 Bytes If PicFlag is TRUE, this is a bit-mapped image of this label's graphics. The rectangle is 100 pixels high by 104 pixels wide in 320 mode; this is also the size of the entire label. This field is not present if PicFlag is FALSE. The remaining fields are present in every GDL document. They start at an offset referred to in this Note as "n". If there is no picture, "n" is 4; if there is a picture, "n" is 5604.
