Only `\pgref` works (and goes to the last layer + of the referenced page). +* If the text overfull the page (slide) then it follows to the next page without + saying explicitly `\pg;`. But `\slideshow` cannot work in such case.\pg+ + +\sec More about design + +* You can use `\backgroundpic{}` for putting an image to the backgroud. +* You can re-declare `\footline` or re-define internal macros for design as + you wish. +* You can put the images or text wherever using `\putimege` or `\puttext` + macros... + +\pg; %------------------------------------------------------------------ + +\sec Putting images and texts wherever + +* `\puttext {}` puts a to the desired place: + It moves the current point and , puts the and returns + back, so the typesetting continues from previous position. The parameters + and are dimensions.
