I want to display an external SVG file in an SVG document.
My external file is here: SVG_example_markup_grid.svg
The file I want to use to display the images is here:vport.svg
The only technique that works (in Firefox, anyway) is the <use> tag and then only if I insert an id="someID" parameter into the external file and add "#someID" onto the end of the href parameter in the display file. <use href="SVG_example_markup_grid.svg#someID".
However, the SVG_example_markup_grid.svg file has elements that start at x="-70" and y="-70" and all elements drawn at coordinates less than zero are not rendered.
How can I get around this?
I need the external file to be displayed inside a clipping rectangle at a possibly reduced scale.

How can I place a complex SVG image (with css-styles!) geo-referenced over an openlayers map so that the document's CSS styles are used with rendering the SVG.
A regular ImageLayer does a fine job of showing the georeferenced svg on the map as an image. But because it is an image, the CSS of the document has no effect on the rendered SVG
The SVG Layer example on the other hand places the SVG into the DOM and makes it react to the document's CSS and reacts when you change the CSS. But it always maps the SVG over the whole planet and seems to hide any layer I place under it.
To give you an idea of the use case: we have an externally generated SVG with several 'groups or layers' in it representing different aspects of infrastructure. This svg has to be put correctly over a map (like we can do with the imagelayer), but we want to be able to selectively show/hide the different 'groups or layers' that are within the SVG.
I guess in the end we would be needing something similar to ol/layer/Image/ImageLayer to happen in the SVG-layer example.
Any suggestions about how to approach this would be very welcome, but working code is also OK ;-)
In the example the image width is 360 degrees and the center is at [0, 0]. For a smaller extent you would need to use the appropriate width and adjust the center used in the transform https://codesandbox.io/s/lucid-poitras-i1qyb?file=/main.js Use an opacity setting to avoid completely hiding the base layer.
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 have an independent SVG image with no filling (fill="none").
I would like to fill it with color, but when I change fill="none" to fill="blue" for all paths, my file becomes a blueish mess:
Source SVG file: https://ufile.io/yaj33
Your SVG is not "clean". It is made up of several hundred open (ie. not closed) path elements. If you want to be able to fill your drawing easily, you'll need to make an SVG with a smaller number of closed shapes, perhaps one for the head, one for each arm and leg, and two open paths for the eyes.
I am trying to get the path data points from an SVG file I am creating for an image-map. The code should look like the below after I save to an SVG file:
<svg height="210" width="400">
<path d="M150 0 L75 200 L225 200 Z" />
</svg>
However, when saving and/or exporting the file, I am getting a bunch of gibberish instead of data points and it looks like the below:
<image id="image4125" opacity=".5" xlink:href="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAO4AAAEUCAYAAAAskArpAAAACXBIWXMAABYlAAAWJQFJUiTwAAAA GXRFWHRTb2Z0d2FyZQBBZG9iZSBJbWFnZVJlYWR5ccllPAAAJYNJREFUeNrsnQd8FNX2x6dsb9nN 7qb3SrqU0ATpIcEnIA9QKRZEUB/6pINYEFFqDH8bwkOeFJGm0t5LqIbewZBAIKQXAtlNdtO37z83...
I have tried using both Adobe Illustrator CC and Inkscape. Any idea how to extract the correct data points using either of these programs, or why I am getting gibberish instead of the data points? I have followed multiple instructions on different websites (including this thread on StackOverflow).
Right now I can get data points to make a rectangle of each area, but the rectangular data points overlap and conflict with other. I am trying to create a polygon path and extract the data points so each shape is unique. Any help is much appreciated.
After a week of research and many tears shed, I finally found the solution. To create SVG images with the path data included when using Adobe Photoshop and Illustrator CC, follow these instructions:
Cut up your image using Photoshop with layers of the image. Save the file as .psd.
Open .psd file in Illustrator. You will then be able to select the different images you cut up in Photoshop.
Select a single image. Open up image trace and trace the image using the Silhouettes preset option.
Click on the Expand button (you will notice the silhouette of your image now has points around the edges; these are your data points).
Open up the color palette. Make the top color white with a red line through it (this removes the fill of the silhouette). Then make the bottom color black (this traces over the trace line between the points).
Finally, on the Attributes panel, you will want to set the image map to Polygon (you can add a new to the attribute below if wanted).
After you repeat these steps over each image layer, you will then save the file as an .svg file with the following settings:
• SVG Profiles: SVG 1.1
• Subsetting: None
• Image location: Link
• Preserve Illustrator Editing Capabilities: unchecked (this will reduce the size of your file for better performance.
• CSS Properties: Style Elements
• Output fewer tspan elements: checked
• Use textPath elements for the text on path: checked
• Responsive: checked
After the file is saved with these options, you will then be able to open the .svg in Sublime, WebStorm, TextEdit, etc., and the path data will be included in the HTML. It is a beautiful sight! Hope this helps whoever is seeking the answer to my same problem!
I doing SVG animation of some physical process using svg (basically I want whole animation as a single svg file).
Example can be seen here: https://s3.amazonaws.com/public-bucket-vzi0CDPFDE4ywJfvfylfpnDW/dwg.svg .
Now I'd like to add label stating: "Time: 1.23ns" displaying current time. I couldnt find any obvioius way to replace contents of text object, insert format current time inside text element.
It would also be great if this animation wasn't using javascript, just SVG animation.
