![]() ![]() You can use this svg image in your epub much as you would any png, jpg, or gif image and with a considerably smaller file-size. To prevent compatibility problems, be sure to save as " Plain SVG" and not as "Inkscape SVG". (Undo CTRL + Z if you mis-click and delete the wrong layer.)ĩ.-In the "File" menu, select "Document Properties." command and in the dialog that appears, select the option "Resize page to content." This will auto-crop the image.ġ0.-Choose menu FILE -> Save As, and save your new svg file with desired filename. Close the dialog.Ĭlick on the red "X" to select it, and delete it, leaving the tracing of your image. I have good results with default settings (which I don't understand yet anyway), so:Ĭlick OK in bottom corner. ![]() ![]() (Portions outside the place-holder frame will not be included in the tracing.)Ĭhoose menu VIEW -> Display Mode -> Outline.Ħ.-Choose menu PATH -> Trace Bitmap. Move the bitmap back to the center of the screen. Select it and move it to the side select the original underlying image, Ĥb.-The bitmap appears, stacked on top of the original image. (A number of arrows appear around the image)Ĥa.-If your image is not already in bitmap format:Ĭhoose menu EDIT -> Make a Bitmap Copy. Choose menu FILE -> Open to open the image file.ģ.-Message offers to "embed" or "link" the file. (Or, let Inkscape convert from your PDF, GIMP, Coreldraw file, any of the common formats such as png, jpeg, tga, tiff, and many more.)Ģ.-Open Inkscape. (Multi-color images may give spotty results, with pieces missing.) Smooth or sharpen the image if needed, clean up spots and specks, crop the image, and save to bmp. Get the portable version and you can run it from anywhere.ġ.-Take a screenshot of the text at a high zoom level, and paste into your favorite graphics editor.įor best results, the image should be in bold dark color on a pale or white background, with good contrast and strong smooth lines. Inkscape, a free and open source drawing program, to create the bitmap tracing. Irfanview (freeware is easy to use, and can automatically save screenshots in various formats. But this little procedure is easy as can be, and only needs a few mouse-clicks to accomplish.Ī graphics editor to tweak and crop your source image. Tutorials about creating Scalable Vector Graphics (in a text editor!) can seem very complex, and Inkscape is mystifying for a new user like me. ![]() It can be used for images other than text. For example, a screenshot, or a page from a pdf document, or a logo created in a graphics editor. This process is very useful if the only thing available is a graphic in raster format (bitmap, png, etc). If you have a foreign-language text fragment but can't use an embedded font, or a beautiful fleuron you want to use as a section divider, or even a page of simple text that you want to keep on a single page, such as a title-page, bitmap-tracing might be the answer. it goes bust with open paths and when the curve is near itself.Edited / updated 16 April 2014 to add information in steps 8, 9, 10, and a link in the P.S.there's no easy to input numeric offset value, it must be adjusted by eye.One can ask "why all this complexity, why do you not simply use Path > Dynamic offset?" Tested, how well the result fits in the original traced curveĬonclusion: quite as good as the original tracing Stroke is outlined (Path > Stroke to Path), removed the fill, new stroke width = 0.5 mmĭivided again like in step 3. In Inkscape the edge will be 2,5mm aside from the path => one of the edges shoud be the wanted centerline trace. New colors are selected to make this explanation clearerĭeleted the red curve, the blue curve got 5 mm wide stroke. If your original was a closed shape like a circle, no divisions at nodes are needed, only Break apart. Remember to confirm all divisions with Path > Break apart. Traced bitmap, fill removed, 0.5mm strokeĭivided with the node tool to 2 separate curves, end segments are deleted. If your curve happens to be uniformly wide and do not cross itself, you can get a good result:Ī bitmap curve, about 5 mm wide, high contrast, high resolution, sharp, no JPG compression artifacts (=easily traceable) I guess you want so called centerline tracing or a way to convert normal Inkscape tracing result to it. ![]()
