This way, you have a combined Bitmap+Scalable Vector document : only the tranparent fill is not scalable, but it will be rendered correctly in PDF viewers.Ī) You need to repeat this operation each time you modify any of your transparent objects.ī) You also need to repeat this if you have transparent objects at different depths.Ĭ) There may be PDF viewers not even handling bitmap tranparency, in which case vector elements in layers below the "Bitmap" layer may not be rendered properly. OK, thinking a little more of the problem, there's a way:Ī) create a layer "Transparent" at the depth of the transparent objects, move transparent objects to this layer ī) view only this layer and "export bitmap", export the whole page as PNG for easy alignment or a subset if the page is very large Ĭ) create a new layer "Bitmap" next to the layer "Transparent", import the PNG you've just saved.ĭ) In the doc properties, note the size of the page, and then scale the bitmap (Object>Transform) to match this size exactly.Į) Ctrl-Shift-A and align object vertically and horizontally with page.į) Turn off the viewing of layer "Transparent" and turn on the layer "Bitmap" before exporting your PDF. This could even work for transparent gradients over solid colour shapes (although not for gradient over gradient).īut it might actually already exist without me knowing it. I am wondering whether it would be possible to script inkscape to actually convert a transparent object into a set of objects having the solid-colour of the rendering ? E.g., if a semi-transparent yellow circle partly covers a blue square, that the script makes 3 objects out of these two : square minus circle (Ctrl+-) in blue, circle minus square in (light) yellow, and circle and square intersection (Ctrl-*) in the green shade that result in the transparent yellow over the green ? E.g., a transparent-to-opaque gradient is rendered as fully opaque, but also plain partly-transparent fills are rendered in a seemingly random way. I am using Okular myself to view PDFs, and most of the transparencies I use (transparent fill or gradient) are rendered appropriately.īut now, the problem lies with the ordinary man's PDF viewer : many (windows or mac users) view a highly damaged PDF. If you select this option and try removing the white color, then only the area around the donut will disappear but the inside of the donut will remain opaque.I am now highly satisfied with the PDF export of inkscape, as it seems to use all the possibilities of PDF standard including transparencies. For example, if you have a PNG of a donut on white background, then the white color will be both inside and outside of the donut. Additionally, we have added an option "Match Outer Pixels Only", which lets you remove only those areas that are in contact with the outer edges of the image. This way, you don't have to know the name or code of the transparent color and you can make the PNG transparent by simply clicking on the color in the PNG. For example, if you click a green pixel, then all greenish pixels will be made transparent. Also, you can interactively click on the input PNG to instantly remove any color and its tones. By increasing the smoothness radius, you can remove more pixels from the edges and make PNG clearer. Tried it a few different ways - coping from internet, pasting into AI, saving directly and opening in AI, Tried opening, pasting and placing into AI. As CF5 answered, you can use the trace bitmap function in Inkscape to get your SVG shapes, but you will need to color the shapes in Aurora 3d. transparent, yet white color should have remained in some parts of the picture. This option makes the pixels on the border between transparency and opacity semi-transparent. When opening it in Illustrator, all colors show as solid black. Web31 I am using export in Inkscape to convert an SVG file to PNG. If you remove the color and the edges of the image still have a pixel or two of the old color, you can refine the edges and smooth them by enabling the "Smooth Edges" checkbox. For example, if the color that you're removing is red, then it will also remove cherry-red, rose-red, wine-red, and similar shades of red. By default, 30% similar color tones are matched but you can change it as you see fit. To match similar color tones, enter the similarity percentage in the settings. This online browser program replaces any solid color and its close color tones in a Portable Network Graphics (PNG) photo or picture with transparent pixels.
