Question

Write a MATLAB code for importing an image and then being able to find all the coordinates that would draw that image on a plot column by column and row by row with a continuous line.

Answer 1

Description

image(C) displays the data in array C as an image. Each element of C specifies the color for 1 pixel of the image. The resulting image is an m-by-n grid of pixels where m is the number of rows and n is the number of columns in C. The row and column indices of the elements determine the centers of the corresponding pixels.

image(x,y,C) specifies the image location. Use x and y to specify the locations of the corners corresponding to C(1,1) and C(m,n). To specify both corners, set x and yas two-element vectors. To specify the first corner and let image determine the other, set x and y as scalar values. The image is stretched and oriented as applicable.

image('CData',C) adds the image to the current axes without replacing existing plots. This syntax is the low-level version of image(C).

image('XData',x,'YData',y,'CData',C)specifies the image location. This syntax is the low-level version of image(x,y,C).

image(___,Name,Value) specifies image properties using one or more name-value pair arguments. You can specify image properties with any of the input argument combinations in the previous syntaxes.

image(ax,___) creates the image in the axes specified by ax instead of in the current axes (gca). The option ax can precede any of the input argument combinations in the previous syntaxes.

im = image(___) returns the Image object created. Use im to set properties of the image after it is created. You can specify this output with any of the input argument combinations in the previous syntaxes.
