![]() ![]() User $ exiftool IMG_3706.HEIC | grep "Camera Model" Its EXIF data confirms it is an HEIC file: user $ exiftool IMG_3706.HEIC | grep "File Type" HEIC files I had downloaded I picked one at random to try and convert to a JPG file: IMG_3706.HEIC. ![]() ![]() This post might seem long-winded but perhaps may be of help to Linux users coming across. I managed to do this but needed to use a range of tools, as illustrated by a couple of examples below for Lubuntu 18.04 and Gentoo Linux. So I set about converting all the HEIC files to JPG files. As far as Linux image viewers go, in Lubuntu 18.04 I find that GPicView 0.2.5 and Geeqie 1.4 cannot display HEIC images, and in Gentoo Linux KDE I find that GQview 2.1.5-r1, Okular 18.08.3 and Gwenview 18.08.3 cannot display HEIC images. The file manager PCManFM in Lubuntu 18.04 displays grey icons rather than thumbnails for these HEIC files, and KDE’s Dolphin 18.08.3 file manager in Gentoo Linux displays green image icons rather than thumbnails for them. I downloaded the HEIC files to a machine running Lubuntu 18.04 and to a machine running Gentoo Linux. I also found that Cirrus, the Android app for ownCloud that I use on my Galaxy Note 8 phone, cannot display HEIC photos either. Now, I can browse and view the above-mentioned shared HEIC images in Google Drive in the Firefox and Chrome browsers in Linux, although an ownCloud site viewed using the same browsers displays the HEIC files as grey icons that can only be downloaded, not opened and viewed in the browser. My interest was simply because I wanted to be able to download the above-mentioned photo files and view them all in the file managers and image-viewing applications in Linux and Android on my various devices. Anyway, I’ll leave you to read the fine print. Apparently the HEIF format is superior to the JPEG format in a number of ways (see the links at the end of my post, especially the image examples given by Nokia), although it is subject to patents and therefore I believe there are certain constraints to coding image files in HEIC format. I have since learnt that these HEIC files were produced by iPhones running iOS 11, encoded using the HEIF (High Efficiency Image File) format. HEIC (High Efficiency Image Container) extension, which I had not come across before. Shown below was zooming to 2500%.I was at an event recently where the attendees were asked to upload their camera and smartphone photos and videos to a shared Google Drive folder. The advantage of a vector graphic can most rapidly be seen when we increase its size. Use "File - Save As" to save your file in SVG format.Otherwise it may appear "cropped" when viewed. If necessary, reduce size of the vectorized image (hold down CTRL to lock ratio), so that it fits on the page.We can resize or move this newly created object, delete the original image, or choose to "Object - Ungroup" in case we need to adapt shapes or colour of sub-object created. Now a vectorized image of your original bitmap will be seen on top of the bitmap. Select "Update" for a preview until settings are fine. ![]() for settings (below shown for 2 colors = "Scans" ): Select the image with the select tool ( ↖). We can import the bitmaps we had already put so much work in to Inkscape and convert them with a few mouse clicks to nice vector graphics.Ĭhoose "File - Import" to import a bitmap file. it will get aliasing artifacts on scaling (see below).īut Inkscape can do even more. The image will then remain a bitmap file, i.e. We could import an image as a bitmap object to Inkscape and save it as an SVG file. There used to be a plugin to do so but this project apparently is discontinued. GIMP v2.8 does not natively export bitmaps to SVG files. ![]()
