I need to save an image with lines on it.
But I can't achieve save image with lines on it.
I displayed image with lines and text (I use insertText()).
I saved only image and text.
Could anyone help me ?
Idisp = getimage(gca);
imwrite(Idisp, 'test.png');
I would appreciate any help.

Converting a jpg file to a svg code.
Hi guys, my friend sent me a jpeg file and I want to add this file to Figma but when ı try to change the structure of file in Figma, ı could not alter the colors and other things. If ı get an svg code and paste it to figma, ı may solve the problems. Thank you!
Short answer: you can't. JPEG is a raster image type (saves info about pixels) and SVG is vector (saves lines and fills mathematically according to degrees, thickness, etc)
I done the following:
I made a screenshot of my linux desktop with gnome-screenshot then converted it to a bmp image and dumped it as raw hex values with xxd -ps.[resolution:969x1920]
From the bmp image i made before, i cropped a small area and exported it to another bmp image and dumped it as raw hex values as well with same method as before.[resolution:47x79]
Now when i go and copy a row of hex values (lets say from the end of the file just to avoid any headers) from the smaller image and try to find it on the other dumped file, it shows that there is not there.
I don't know much from image formats, i just want to know if there is something fundamental behind it that i am missing and i have to study before trying again something similar.
Thank you in advance!
I was trying to extract text from an image using pytessaract, but it skipped a portion of image. But similar text was extracted from the same image. And when I made an image by cropping the skipped portion and extracted the text , all the text was extracted. Can anyone help me to figure out what is the reason. Thank you all in advance.
I am trying to save an image that I generated on a Matlab Gui. I tried following code with a push button:
[Save,savename] = uiputfile('*.bmp','Save Figure As...')
fname=fullfile(savename,Save);
imwrite(handles.axes2, 'fname', 'bmp');
It doesn't work. Can anyone please help?
imwrite is for saving image data (as a matrix) to an image file. If you want to save the figure, you will want to use saveas.
If you need to save an image of a specific axes, you can use getframe to save a screenshot of the specified axes, then convert this to an image using frame2im and then use imwrite to save this image data to a file.
frame = getframe(handles.axes2);
im = frame2im(frame);
imwrite(im, fname)
I have a image and some contours as bellow figure. I want to save the output into image (png or jpg). The saved image only contains the image region without the matlab window. Let see my example in the figure. Could you have me implement it by matlab? This is my code to make output figure
img = imread('coins.png');
mask_red=zeros(size(img));
mask_green=zeros(size(img));
mask_red(30:160,40:170)=1;
mask_green(70:100,60:130)=1;
imagesc(uint8(img),[0 255]),colormap(gray),axis off;axis equal,
hold on;
[c1,h1] = contour(mask_red,[0 0],'r','Linewidth',3);
[c2,h2] = contour(mask_green,[0 0],'g','Linewidth',3);
hold off;
%% Save output figure
Use the getframe and cdata idiom. If the figure is open, simply do this:
f = getframe;
im = f.cdata;
im will contain the image that was contained inside your frame as a RGB image. Running your code in your post, then the above code, then doing imshow(im), we get:
If you want to save the image, just use imwrite:
imwrite(im, 'coins_final.png');
The image will be saved in a file called coins_final.png.
