I have generated a large SVG file, but when viewing it in a web browser I can't zoom in far enough to see all the detail in it. Is there something I can do in the SVG source code to allow this?
The SVG is very tall and thin (1000px wide, 11000px high). When I open it in a browser by default the browser fits the whole thing into the view port, so it's just like a thin stripe down the center of the page - far too zoomed out to actually see anything. The browser allows me to zoom in to some extent, but only up to a certain point and then further zooming is not possible. Is this something that I can control from the SVG code?
The <svg> element looks like this:
<svg viewBox="0 0 1000 11000" version="1.2" xmlns="http://www.w3.org/2000/svg">
Please note, I am not embedding the SVG in an HTML page, I just have an SVG. Since the most common SVG viewer is a web browser I want people to be able to view the document properly in one.
Add a suitable height to the SVG. That will force the browser to render it that tall (and the user has to scroll to see the whole thing). For example 5000px tall:
<svg height="5000" viewBox="0 0 1000 11000" version="1.2" xmlns="http://www.w3.org/2000/svg">

I'm struggling to find a way of printing a wide SVG image. This is a common problem so let me explain my specific problem.
The image is wide and so I need to tile it (poster fashion) across about 5 or 6 A4 sheets (actual count not important). My first problem is that the default Print dialog in my Firefox or Chrome browsers, under Windows, do not allow me to scale the image height to fit the page height while also spreading the image width across multiple pages.
Someone else suggested using Inkscape to convert to PDF format as the Print dialog in Acrobat reader has better support for tiling. Well, it does, but Inkscape does not deal with embedded images (e.g. PNG or JPG). Worse still, it generates huge square error markers saying "Linked image not found" all over. These are also preserved in the generated PDF which makes it useless.
There are lots of online tools that claim they can convert SVG to PDF. I tried a handful and none coped with embedded images. They were simply discarded.
So, I'm basically looking for any route to print a wide SVG image onto a horizontal series of pages, and that preserves any embedded PNG/JPG images.
[Edit]
Some of the online results:
zamzar -- images discarded
cloudconvert -- simply used inkscape
convertio -- best of the bunch, but opacity ignored on images
online-convert.com -- images discarded
pdfresizer -- simply used inkscape
freefileconvert -- simply used inkscape
onlineconvertfree -- failed with basic SVG
pdfaid -- massively failed with basic SVG
[Edit 2]
Here are a few lines of code that show one of the embedded internet-based PNG references. This one is designed to provide a faint background image underneath the subsequent SVG shapes. Hence the opacity of 12%.
<defs>
<pattern id="img2" width="50%" height="100%" >
<image xlink:href="https://clipartart.com/images/tree-branch-clipart-png-4.png" x="0" y="0" width="50%" height="100%" />
</pattern>
</defs>
<rect width="100%" height="100%" fill="url(#img2)" fill-opacity="0.12" />
I've had time to experiment with this further (and so wasting printer paper by the shed-load).
1) Inkscape deliberately does not support Internet image references (e.g. http) for "security reasons". As mentioned, it puts a horrible error marker in the view of the loaded SVG and I have found no way to edit it out. Hence, it gets saved in any PDF version.
2) If I download local copies of the images and change their http:// references to equivalent file:/// (yes, 3 slashes) then they are accepted.
3) This allows a PDF copy to be saved, but if any of the images had an opacity (e.g. a background image) then that gets lost and it is full opacity in the PDF. This may be a conversion issue or a PDF limitation -- I do not know.
4) Since I then have local copies of the images, they can be changed to implement any faintness required "at source".
5) The Acrobat Print dialog has a Poster option for tiling the pages of a wide image. Ensuring no 'cut marks' or 'labels' are added, you can set a 'Tile scale' that keeps the height within one page, and it will spread it over as many pages as necessary for the width. On the basis of the scaling, it selects landscape/portrait itself and ignores any selection of your own.
So, problems? Yes, the Acrobat 'Overlap' setting is a mystery, leaving a thin white margin on either one or both of adjoining sheets in the output. I have not been able to correlate the width of this margin, or the appearance on one or both sheets, with this setting.
Via the Preferences button, I can get to the normal printer preferences dialog, where I can request 'Borderless printing'. Rather than fixing the issue, this just makes the correlations even more mysterious.
I need some help to figure out how I can adjust the resizing of an SVG graphic when displayed on my web page.
Here are joined 2 screenshots of the graphics, one shows the graphics on a desktop wide screen, and the other on a smartphone
My problem is the graphics are too small on the smartphone. How can I make it bigger? I didn't anything about the responsiveness of this graphics, just the plain SVG in my web page. So I guess something can be made but I don't know what exactly.
Here is the beginning of the SVG graphics:
<svg viewbox="0 0 1920 632" xmlns="http://www.w3.org/2000/svg" preserveAspectRatio="xMidYMid meet">
<title>graphics</title>
<g style="isolation:isolate">
<g data-name="before animation starts" id="0482fa28-2c72-43bc-8627-b57f09f318d3">
<path id="main-oval" class="main-oval" d="M1354.63,260.62C1338.38,142.2,1144.68,71,922,101.54c-109.4,15-205.35,51.8-272.82,99.38-69.92,49.26-109.23,110-101,170.29,16.31,118.42,210,189.59,432.62,159.07,110.79-15.17,207.86-52.73,275.44-101.15C1324.59,380.18,1362.8,320.12,1354.63,260.62Z" data-name="oval"></path>...
Thanks
Attribute names in SVG are case-sensitive. So viewbox should be viewBox.
It is possible that there are other things wring, but I can't tell without seeing the complete SVG file.
Because your SVG has a viewBox attribute without a width and height attribute it is by default responsive and will scale to fit it's parent container.
In the case of your mobile view, it is the parent container that is restricting the size rather than anything in your SVG. Try inspecting the width, margin and padding of the parent container to ensure it is 100% wide and your SVG will scale to suit.
If the SVG is still not quite legible after that you will need to modify the graphic using CSS media queries to scale and transform specific elements. That is beyond the scope of the question so I won't go into it here.
I'm trying to have a SVG path scale to fit the entire container element, without stretching or being trimmed. The SVG is the one below. As you can see, it's a simple border.
<svg preserveAspectRatio="none" viewBox="0 0 370 80" height="100%" width="100%">
<path vector-effect="non-scaling-stroke" d="M359,70C359,70,300,70,185,70C84,70,9,70,9,70C9,70,9,60,9,40C9,24,9,10,9,10C9,10,84,10,185,10C300,10,359,10,359,10C359,10,359,24,359,40C359,60,359,70,359,70C359,70,359,70,359,70"/>
</svg>
Then I have an element that could have different sizes, because it's responsive and because I use it in various cases where width or height can be different. I can't succeed in having the SVG that expands its path by always staying inside the viewport, but scaling without preserving aspect ratio. It doesn't seem a difficult logical thing to do, but I tried various options without success.
EDIT
I was able to scale this SVG, by setting whatever dimensions I wanted. Why does the first not work, but this works instead?
<svg preserveAspectRatio="none" viewBox="0 0 404 77" height="100%" width="100%">
<path vector-effect="non-scaling-stroke" d="m0,0l404,0l0,77l-404,0l0,-77z"/>
</svg>
The short answer is no. What you want to do (as I understand it) is not possible. In SVG you can scale to fit the container (using constant aspect ratio), or you can stretch (ignoring aspect ratio).
There is no way currently to keep some parts of the SVG static and stretch other parts. Unless, of course, you use Javascript to manipulate the contents of the SVG.
What you may want to do is consider using an SVG as the source image for a CSS border-image (see http://www.w3.org/TR/css3-background/#border-images). Perhaps that is the sort of thing you were after?
I've a web page in which there is a SVG box <svg id='graph'>...</svg>.
I would like to give to the user the possibility to zoom in the SVG box.
I use for this purpose document.getElementById("graph").currentScale*=2; if I want to double the size of the box, for example.
The problem is that all the window is resized, even the HTML elements outside the box.
Do you know the origin of this problem please ?
In order to apply zoom to only svg , use this...
<svg>
<g transform="scale(2)">
</g>
</svg>
This may be off the mark without knowing which browser you're using, but you may not be able to implement currentScale if you're using anything other than Internet Explorer or Microsoft Edge. You can test this for yourself by trying this JSBin in different browsers and see where it scales.
Diving into this deeper, a Google search of "SVG currentScale" found these bug threads from Google and Mozilla discussing similar issues. The Mozilla thread discusses it was a choice made specifically for consistency's sake. SVG's currentScale only applies to container elements and not to inner elements. This could interfere with functions like zoomAndPan used on inner SVG elements. Additionally, better cross-browser solutions are already in place such as scale() via the transform property.
I have an SVG I am building with Javascript. I load in a large SVG file, break it apart into pieces all drawn with paths, and place each element in my page. I'm only using these SVGs as masks for other images I am loading. Basically my structure is like the following.
<svg xmlns="http://www.w3.org/2000/svg" version="1.1" viewBox="26.750152587890625 10.117172241210938 197.24969482421875 348.1596221923828" width="197.25" height="348.16015625">
<mask id="designMask" maskContentUnits="objectBoundingBox">
<g id="CutContour1bg">
<path d="[my path coords]" style="fill:#FFFFFF;">
</g>
</mask>
<image href="http://myImage.jpg" style="mask: url(#designMask);" width="800px" height="800px" x="26.75" y="10.1171875">
</svg>
This renders the image being masked by my SVG perfect, in FF, IE9, Chrome, Safari 5.1 (desktop). In mobile safari however, the image does not render properly. I trace out coords of the mask, they are all correct. In FF I can see the SVG load (all black) then disappear as it becomes the mask. (I am waiting until the design is loaded, then wrap my <g> with <mask> since FF has an issue looking for the mask before the content is loaded.
This tells me the mask's position is exactly where it needs to be, but the maskContentUnits are not. They remain in the top left corner instead of the object's bounding box, like I'm telling it. I can barely see part of the image in the mask, so the mask units are correct, but I cannot get the maskContentUnits to work or be read in mobile safari.
Has anyone ever seen this issue, or any idea how to correct it? I hate having this work everywhere except mobile safari, as it is meant to mostly work on mobile... which defeats its not purpose haha.
Thanks!
I haven't found a way to make maskContentUnits work properly in mobile safari yet, I'm pretty sure it's just not recognized yet like other browsers. But I figured out a 'hack' to make the example work.
The issue is, the mask area resides in the top left corner of the browser, rather than of the svg object being used as the mask. So if you have an svg in the middle of your page, the image being masked will not follow the same positioning.
The way I found for it to work, is, I wrapped the svg inside a div with the same width as the svg, and modify the position of the div instead of the svg. This way the mask is technically still in the 'top left' corner, but of the div rather than the offset position of the svg.
If anyone finds a better way, to make maskContentUnits render proper in mobile safari, I'd like to hear it!
