resizes an image proportional relative to a mimum number of pixels
Description
This function is used to limit an image size before image processing to guarantee a defined processing time. The image is always scaled proportionally.
It is possible to scale on maximum value for row or col, or on defined rows number, defined cols number or defined size. If there is need to add a border, since the given format differenz from the original images's proportion, a color can specified for the border;

Example Illustration
Syntax
I=imresizep(I,maxrc,[defcol])
Input Parameter
I: | | Images |
maxrc: | | maximum number of rows or cols; or [rw nan] or [nan col]; |
defcol: | | color for borders to extend; default is 255 |
Output Parameter
I: | | resized image smaller than [maxrc x maxrc] |
Examples
I=imread('peppers.png'); whos I
imresizep(I,480); pause
imresizep(I,[nan 1080]);pause
imresizep(I,[1080 nan]);
pause; imresizep(I,[700 2000],255);
pause; imresizep(I,[2000 700],100);
