Some useful functions are created concerning TD images/pictures which are present in SalExtension archive.
For each function, the location in which library you can find them is added.


For TD versions up to 5.1, use the ANSI version of SalExtension archive.

SalPicButtonSetFromFile (from SalPic.apl) Loads an image from disk and sets it as picture on a button
SalPicConcatHandle (from SalPic.apl) Concatenates to bitmaps (HBITMAP handle) together

SalPicLoadFromDLL (from SalPic.apl) Loads an icon from a DLL and returns the HIcon windows handle.

The picture number is the resource number, starting at 1

SalPicSetFileX (from SalPic.apl) Inserts a file's contents into a picture.

Supports more formats and better quality than SalPicSetFile

SalPicSetX (from SalPic.apl) Works like SalPicSet, but the resource can be specified in a string
