![]() General-purpose GIF editing command-line library gifsicle. In thisĮxample, we apply the described method to a given GIF my_gif using pygifsicle, a porting of the Used here) is saving just the differences between the following frames. GIF files can be compressed in several ways, the most common one method (the one Also I suggest you look at and compile 'giftrans' which can output and directly manipulate the color palette of GIF file format. It might just do it simply in the way you want. ![]() When the process is finished and the GIF is unexpectedly big. I have not looked but you could try 'gifsicle' which also has color replacement options. This can be useful when theĮlaboration process for the GIF is not finished yet (for instance if someĮlaboration on specific frames stills need to happen), but it can be an issue ![]() Heavy, as the created GIF is not optimized. When creating a GIF using imageio the resulting images can get quite imwrite ( output, img, plugin = "pillow", extension = ".jpeg" ) Optimizing a GIF using pygifsicle # imwrite ( output, img, plugin = "pillow", extension = ".png" ) # write as JPG output = io. imread ( 'imageio:astronaut.png' ) # write as PNG output = io. Thank you.Import imageio.v3 as iio import io # load an example image img = iio. I'm grateful for guidance on removing white background, however owing to inexperience with vector graphics, I 'm lost & wasting too much time on getting basics right so need help. Please suggest value for black or very dark area and one other color of your choice by transparency. However you can easily modify it : open the Filters Editor, then apply the filter, then add a new Effect Color Matrix, then in the fourth line at the bottom of the Color Matrix, change the two last numbers for example from "1" and "0" to "10" and "-1" You will see that transparency is now much more confined to white or very pale areas. This kind of filter already exists : Transparency tool/Light eraser but it's progressive and based on lightness and not color. Prkos wrote: Hey Ivan! Got any tips on what primitives to use to create a filter that makes all white areas transparent?īTW I tried the new filters they are a great addition, and it's nice they are all marked as new makes it easier to explore. We get this type of question so much, that I'm in the process of writing kind of an overview, to put in an FAQ for this forum. But if it is a rather simple line drawing, like a cartoon, it should be "doable" ( ) especially if it's all solid white and you want only full transparency. If your bitmap is a photo or something like it, this will be very difficult to do with Inkscape (if not impossible). Unfortunately, I can't remember what it is But maybe someone else can tell you? Manipulating the XML code, I think? However, if you want alpha transparency, where there is some solid white, which would be fully transparent, and "shades" of white which would be partiallly transparent, while "not white" would be opaque, you'll do better with a Mask, rather than a Clip. That said, I believe there is some sort of trick by which this can be done. But with vectors, no pixels, so no way to select the white areas. Raster graphics programs achieve this by selecting every pixel with white in it. The reason Inkscape can't select colors, is because of the nature of vector graphics, which does not recognize pixels.
