Object PmgRasterImage (Raster image)

Description:
This object serves for displaying images with raster (PNG, JPG, GIF, TIF, BMP ...) and vector (SVG, WMF) graphic.
The vector SVG graphic is rendered as vector, but after that it is processed the same way as raster graphic. The advantage of vector graphic is thar the original image redimensioning does not reduce the image quality keeping the image "nice". Therefore all images supplied with the PROMOTIC system are in SVG format.
For the designer, creating the pictures to fit his needs it may be easier to make for example PNG or JPG format images.

The PmgRasterImage object allows:
- rotation (see the "Flip and rotate" configurator)
- coloring (see the "Light color" configurator)
- transparency of entire image (see the "Enable opacity" configurator)
- image exclusion display (see the "Crop image" configurator)


The Pmg object doesn't include the data itself from the file, it is only the reference to the file. The designer must ensure so that the corresponding file is always accessible by the application - by correctly entering the filename and setting the path to the file. It is recommended to use the files located on #pmres: or #appres: paths only
