- ICONS
- -------------------------------------------------------------------
-
- Icons are a special kind of image that are drawn as they are used, they
- are not stored as bit images.
-
- Icons are created with the ICON Editor. The ICON editor is included
- with the TEGL Windows Toolkit but is not included with the Intro Paks.
-
- PutPict(x,y: Word; Icon: Pointer; Color: Word);
-
- PutPict is the routine that draws an icon. The x,y parameters are the
- screen location to draw at. Icon points to a valid icon image, there
- is no checking done to see if the icon is a correct image. Color is
- the color that BLACK in the icon will be replaced with.
-
- PutPict is NOT viewport relative and is never clipped.
-
-
- These are all the icons in teglicon.tpu and moreicon.tpu. Note that
- the actual name to refer to an icon is image<iconname>.

-
- This example simply create a frame a sticks an icon on it.
- Note that we use the x and y coordiates from the ImageStkPtr
- to place the iconimage.

-
- PictSize(VAR width,height: Word; Icon: Pointer);
-
- This function returns the size of an icon in pixels. Icon is the
- icon that we are interrogating. Width and Height return the
- respective x and y dimentions of the icon.
-
-
- This next example shows a routine that draws an icon relative to
- a frame and won't write outside the frame boundaries.

- teglicon, moreicon,
- tgraph, fastgrph,
- teglunit, teglmain;
-
-
- {-- draw an icon image relative to a frame, do not draw it if }
- {-- it writes outside the frame }

- x,y: Word; Icon: Pointer; Color: Word);

- fmaxx := ifs^.x1 - ifs^.x + 1;
- fmaxy := ifs^.y1 - ifs^.y + 1;
- {-- check to see the icon will fit }
- if ((x + dx) > fmaxx) OR ((y + dy) > fmaxy) THEN exit;
- putpict(ifs^.x+x,ifs^.y+y,icon,color);
