Hi every one.
I am tying to build a Zooming application, a zoom by level type application.
i manege to create the following:
[1]first i to build a zoom Meter that spited overall zoom into Levels and
sub zooms for each level.
[2]each level represent a set of divided image increasing by level and
ordered by Level,column and row.
[3]and i create procedure that shift image to zoom center by this
transformation:
Z(x1,y1)=(x1-x2,y1-y2):x1,y1 center before zoom;x2,y2:center after zoom.
[4]then i create a procedure that combine's the image.
[5]and procedure to calculate Subtractive of a point in other level by
this transformation:
S(x1,y1)=((x1*d2)/d1,(y1*d`2)/d`1):x1,y1 target point; d1,d2 old
dimension;d`1,d`2: new dimension.
[6]and procedure that detects the viewed parts of image in the view
port(putting the result in two dimension array of Boolean [Column][Row])
then during my analysis to the program i ran into many problems like:
1. [1]what is the effective methods to creates fixed frame (by dimensions of
the form) that represent a 'view' part of the image, that capable to pan throw
the total image ,zoom from /to image plus move throw the levels, with 'aware'
for border updates.
[2]effective algorithms for transformation like(move ,zoom) for my levels;
if you please, i need some help in this manner ,please put some hints to solve
my problem.
thank you very much for reading may request.
