mysticview.library is the third abstraction layer in top of
guigfx.library and render.library.
mysticview.library implements an RTG image display class. it
renders images of any kind to a RastPort on any screenmode.
there are no considerations on the programmer's side
required for issues such as screenmodes, aspect ratios,
scaling, OCS/ECS/AGA, HAM, chunky/planar, 8bit, 1bit, 24bit
or alike. all you have to do is to specify a Screen, a
RastPort, a guigfx.library 'picture' and some attributes.
images will be rendered, scaled and dithered automatically,
when needed.
rendering and layouting takes place in the background. you
create the object, and forget it. the background task
instantly reacts to changes of attributes and will redraw
the display when needed. opaque scaling and SIMPLE_REFRESH
is easily implemented, you only need to supply new
attributes. a protection mechanism is implemented for
sharing the RastPort between your application and the
background task of mysticview.library.
this library makes it REALLY EASY to display any kind of
pictures inside any kind of application. there are no
examples included in this archive - the basic implementation
looks like this:
APTR picture, mview;
picture = LoadPicture("filename", TAG_DONE);
mview = MV_Create(screen, rastport, MVIEW_Picture, picture,
TAG_DONE);
if (mview)
{
MV_DrawOn(mview);
while(...) { /* image visible */ }
}
MV_Delete(mview);
DeletePicture(picture);
mysticview.library is the fully encapsulated display engine
of the image viewer 'MysticView'. you are free to use this
library in freeware and shareware applications.
