Variablen of the Type Picture save Two-Dimensional Graphics.
These graphics can be raster graphics in the formats BMP (bitmap), PNG (Portable Network Graphic) or JPEG, but also metafiles (extended metafile).
PNG files and 32bit bitmaps support transparency over the so-called alpha channel.
Graphics can be provided with additional metadata, such as a hotspot location, a scale unit (DPI), and marker areas. This metadata is updated during scaling and rotation operations.
Variables of the Type Picture can be edited using the GDI+ Graphics object, which can be determined using the Graphics attribute. For this purpose, it is necessary to call the BeginModify function before editing and the EndModify function at the end of the processing. This gives the interpreter the ability to respond to changes in the content of the image with a rule check.
Graphics can be prepared very well in a constant of the Type Picture and assigned to a variable from the type picture at run time.
