The code below creates a circle using the R grid graphics. I would expect the chart to fill the entire screen instead it fills only a fraction (top-left) of the screen. I am on a Windows computer and here is what the produced svg looks like when I open it using Chrome. How can I draw a circle that would fill the entire screen? I am looking to understand how things work so would appreciate someone teaching me the part I am missing here or pointing me to a reference that I can learn from.
library("grid")
library("gridSVG")
grid.newpage()
grid.circle()
grid.export("rectangle.svg")

I've an image like the one in the following link
https://www.freecodecamp.org/news/how-to-center-an-image-using-text-align/
I want to cut and move one half of the image close to the other (one building close to the other in the example image share above). In real case, I have a similar image with white space in between. To cut one part of an image I do Object-> Clip -> Set on the selection. This crops the selection alone. But I am not sure how to select and move the selection.
Could someone please help?
Duplicate the image, then clip both images to the two parts that you need. Then use snapping to move them both together exactly.
Or (better), use a raster graphics editing tool of your choice and do the same. While the above-described workflow works, Inkscape, being a vector graphics editor, is not the appropriate tool for this kind of thing.
I am new to Illustrator. I watched some videos about image tracing to make vectors and it worked for me so far until today. If i try to make simple colours and shapes into vectors it is brilliant. Today though i have an image that uses 3 colours and a pattern. The colours i use are black, orange and dark grey. I have a pattern of thick grey lines covering 50% of the image. I played with the tracing settings for hours but it just refuses to keep the lines straight. It makes the lines rounded. Check out the first image versus the second one.

Image Trace is a great tool, but it's not perfect. Adjusting the settings may improve it but it won't be perfect. If possible depending on the design, especially one as simple as the example images you've included here you should use another method. To recreate the lines there maybe:
create a line at the angle you want (Pen or Line tool),
duplicate that line and move it above the first,
align the two,
use the blend tool to add as many copies between the two as needed,
expand them,
make a background to fill the negative space and move behind the lines,
create a rectangle shape with no fill and position above the others,
shape build the excess areas away
Example
I am looking for a way to modify the visual representation in Netlogo. My screen size is small, so when I want to capture a screenshot of my simulation result, the legends are not much readable. Even making the windows bigger does not affect the fonts. I wish there was also a way to make the curves in a plot thicker.
Any ideas?
Thanks,
I want to make the whole webpage into a graph, like a blueprint (the colour scheming). And then i want to plot a graph in the same page. So should i use some code to make the grid or should i just make an image file and make it the background.
The grid should be preferably something like this : Graph, or with the proper coloring Blueprint Graph
If code is suggested, please give an overview of how to do so.
Thank You.
This sounds like something you could do with HTML5 Canvas, although maybe that's above and beyond what you're looking for. Here's a pretty good free course that has relevant examples.
Since you're going to be plotting points on the graph, your best bet is to create an element, such as a <div>, and give it a fixed width and height. Then apply a background image of the graph paper to that element. You'll need to use absolute positioning when plotting points, so it's key that the graph stays in place and doesn't get skewed based on differing viewports.
If you wanted the entire viewport to be a graph, you'll need to reference the upper-left corner when plotting points (start at 0,0) since users' browsers will have varying widths and heights.
I'm creating a web app in ASP.NET like this one:
http://www.zazzle.com/cr/design/pt-mug
I know how to do everything except wrapping an image around an object.
It would be a simple task to do if I would only have to stack an image on
top of the other, if they were flat, but if it is a round object, as this mug
is, it's kinda tricky.
My first guess was to create some sort of algorithm for GDI+ that would
simulate "wrapping" image around an object (actualy it wouldn't be an 3d object,
it would just be a screenshot of it).
I figured it would be to raw approach and it would result in very bad quality,
if I could ever make it work.
So, my second guess was to implement somekind of 3d renderer to whom I would
give an image map for some object, it would render me that image onto an object
and in real time return me rendered image. Is that posible?
Is there any other way? Where do I start?
If you are willing to try a commercial product, my company makes a raster processing SDK for .NET called DotImage. If you try it, take a look at PolygonTransform. You supply a polygon as a list of points, and the class warps the image to fit inside the polygon. If you need sample code for it, let me know.
It might be some sort of OpenGL 3D rendering, but an image could easily be morphed in a purely 2D way for this effect. Horizontally, it would need to be squished where it goes off the side of the cup. Each column of pixels needs to be shifted vertically by varying amounts depending on which column - such that a horizontal line the image would become like a "U" shape. With the right parameters, such a morph could mimic the proper 3D shape. Lighting effects could be applied to, by brightening/darkening the image a bit in the right places.
