I wanted to tell you know how much I am enjoying your software. I bought the 3D text maker, now I bought the 3D animation maker. Both of these programs will make my video projects really stand out.

This program looks very useful. I am definitely going to download and try it. Animation 3D looks very useful as well. It's amazing how many software titles get introduced in bitsdujour that I would not otherwise have encountered.

I just finished experimenting with 3D Animation Maker. Wow, I am very impressed! I exported one of the samples as an avi and am very pleased with the quality. Thank you for the deal--the purchase was a "no brainer" after the trial. I will definitely be considering Presentation 3D in the future.

When you convert from raster images like PNG to SVG or JPG to SVG, it will convert your forms and objects in black-and-white images in vector graphics that can be enlarged without loss of quality. Then you can paint them in any vector graphics editor such as Inkscape .

Conversion of ordinary pictures, most likely, won’t have the desired result.

For best results in convert to SVG, use image with solid background.

• To convert to SVG, select the file, wait for it to download on our server.
• Supports almost all image formats (PNG, JPG, BMP and other). File size is not limited, but the larger the file, the more time it will take to convert.
• After the conversion, you will see your original file and the result under it.
• Download the result via the link.

Why do you need the SVG format and how to use it? After convert PNG to SVG or JPG to SVG

SVG (Scalable Vector Graphics) is an XML-based vector graphics format
The advantage is that you can change the image size without losing the quality and details. When you increase the size, the vector image preserves the shape of the curves, so the image can be displayed at any resolution.

Sometimes it becomes necessary to save svg as png using the browser. Unfortunately, the browser does not have a magic API that would allow this to be done without various hacks. What to do if you still want to achieve what you want?

The first idea that came to my mind was to do this through canvas, which has a method toDataURL("image/png");
So, I wrote a simple script: jsfiddle, github:

Var html = document.querySelector("svg").parentNode.innerHTML; var imgsrc = "data:image/svg+xml;base64," + btoa(html); var canvas = document.querySelector("canvas"), context = canvas.getContext("2d"); canvas.setAttribute("width", 526); canvas.setAttribute("height", 233); var image = new Image; image.src = imgsrc; image.onload = function () ( context.drawImage(image, 0, 0); var canvasdata = canvas.toDataURL("image/png"); var a = document.createElement("a"); a.textContent = " save"; a.download = "export_" + Date.now() + ".png"; a.href = canvasdata; document.body.appendChild(a); canvas.parentNode.removeChild(canvas); );

The essence of the script is simple: I converted svg to dataUri, loaded it via image, drew a picture on canvas and turned it into png. It seemed that the goal had been achieved and we could relax. This approach worked in Firefox and Chrome, but when I opened it in everyone's favorite browser, IE, I got this wonderful error:

The fact is that IE believes that the image was loaded from another host. Unfortunately, you won't be able to set origin for dataUri. Actually, a description of the rules can be found here: https://html.spec.whatwg.org/multipage/scripting.html#security-with-canvas-elements. It was possible, of course, to proxy the svg through the server, and then everything would work, but I wanted a purely client-side solution.

And then I remembered the wonderful canvg library. Using this library, I draw svg on canvas, and then proceed as in the first option: take toDataURL("image/png") . The result is this simple code: github:

Var svg = document.querySelector("svg"); var canvas = document.createElement("canvas"); canvas.height = svg.getAttribute("height"); canvas.width = svg.getAttribute("width"); canvg(canvas, svg.parentNode.innerHTML.trim()); var dataURL = canvas.toDataURL("image/png"); var data = atob(dataURL.substring("data:image/png;base64,".length)), asArray = new Uint8Array(data.length); for (var i = 0, len = data.length; i< len; ++i) { asArray[i] = data.charCodeAt(i); } var blob = new Blob(, {type: "image/png"}); saveAs(blob, "export_" + Date.now() + ".png");

It’s worth mentioning here that I also used the FileSaver library to bring up the save dialog box.
That's all, we have achieved the desired result.

One thing worth noting is that I wondered about saving svg to png when I was writing the tauCharts export plugin. Since styles in svg are set from external file To achieve maximum similarity with the original svg, I insert an inline style into the svg. And we get this result.

I hope the article will be useful to you and save your time.

Doesn't seem to work very well. Here's an example that uses the -flatten flag for convert:

Sudo apt-get install potrace imagemagick convert -flatten input.png output.ppm potrace -s output.ppm -o output.svg rm output.ppm

Another interesting phenomenon is that you can use PPM (256 * 3 colors, i.e. RGB), PPM (256 colors, i.e. grayscale) or PPM (2 colors only, i.e. white or black only). From my limited observations, it would seem that in images that are anti-aliased, PPM and PPM (which I see produce identical SVGs) shrink the colored area, while PPM expands the colored area (albeit slightly). Presumably this is the difference between the pixel > (256 / 2) test and the pixel > 0 test. You can switch between them by changing the file extension, i.e. the following uses PPM:

Sudo apt-get install potrace imagemagick convert -flatten input.png output.pbm potrace -s output.pbm -o output.svg rm output.pbm

How to convert a PNG image to SVG?

However, this is not ideal.

Png is a bitmap style and SVG is a vector style graphic design, which supports raster images, so it won't convert the image to vectors, but just the image embedded in a vector format. You can do this using http://www.inkscape.org/ which is free. It will inject it, however it also has a Live Trace engine that will try to convert it to paths if you want (using potrace). See Direct Tracing in Adobe Illustrator (commercial) is an example:

If you are in some Linux system, imagemagick is perfect. Those.

Convert somefile.png somefile.svg

This works with tons of different formats.

However, for other media such as video and audio (ffmpeg), I know you clearly stated png to svg; It's still about the media.

Ffmpeg -i somefile.mp3 somefile.ogg

Just a hint if you want to go through a lot of files; loop using basic shell tricks.

For f in *.jpg; do convert $f $(f%jpg)png; done

This removes the jpg and adds the png which tells it to convert what you want.

There is a website where you can upload your image and see the result.

But if you want to download the svg image, you need to register. (If you register you will receive 2 images for free)

with adobe illustrator:

Open Adobe Illustrator. Click "File" and select "Open" to load the .PNG file into the program. Extract the image as needed before saving it as an .SVG file. Click "File" and select "Save As." Create a new file name or use an existing name. Make sure the selected file type is SVG. Select a directory and click "Save" to save the file.

i prefer AI because you can make any changes

I assume you want to write software for this. To do this naively, you simply find the lines and set the vectors. To do this intelligently, you try to fit the figures to the drawing (model fitting). Additionally, you should try to define raster regions (regions that you can't model using shames or applying textures. I wouldn't recommend going this route as it will take quite a long time and require a bit of graphics and computer vision knowledge However, the output will be significantly and scale much better than your original result.
