![]() If no descriptor is specified, it defaults to descriptor of 1x. Each image source contains a URL of an image and a pixel density descriptor. This prop has precedence over source prop.Ī string representing comma separated list of possible candidate image source. TypeĪ string representing the remote URL of the image. Refer to Apple's documentation for the current list of supported camera models (for iOS 12, see ). In addition, iOS supports several RAW image formats. The currently supported formats are png, jpg, jpeg, bmp, gif, webp, psd (iOS only). (For more information see Cache Control for Images). A cache property can be added to control how networked request interacts with the local cache. The native side will then choose the best uri to display based on the measured size of the image container. This prop can also contain several remote URLs, specified together with their width and height and potentially with scale/other URI arguments. The image source (either a remote URL or a local file resource). If the image is larger than the view, scale it down uniformly so that it is contained in the view.Įnum( 'cover', 'contain', 'stretch', 'repeat', 'center') The image will keep its size and aspect ratio, unless it is larger than the view, in which case it will be scaled down uniformly so that it is contained in the view.Ĭenter: Center the image in the view along both dimensions. Repeat: Repeat the image to cover the frame of the view. Stretch: Scale width and height independently, This may change the aspect ratio of the src. at least one dimension of the scaled image will be equal to the corresponding dimension of the view (minus padding)Ĭontain: Scale the image uniformly (maintain the image's aspect ratio) so that both dimensions (width and height) of the image will be equal to or less than the corresponding dimension of the view (minus padding).both dimensions (width and height) of the image will be equal to or larger than the corresponding dimension of the view (minus padding).Defaults to cover.Ĭover: Scale the image uniformly (maintain the image's aspect ratio) so that TypeĮnum( 'no-referrer', 'no-referrer-when-downgrade', 'origin', 'origin-when-cross-origin', 'same-origin', 'strict-origin', 'strict-origin-when-cross-origin', 'unsafe-url')ĭetermines how to resize the image when the frame doesn't match the raw image dimensions. Works similar to referrerpolicy attribute in HTML. Sets the value for Referrer-Policy header in the image request. TypeĪ string indicating which referrer to use when fetching the resource. More details about resize and scale can be found at. It should also be used if the image is slightly bigger than the view. This should be used if the image is smaller than the view. Compared to resize, scale is faster (usually hardware accelerated) and produces higher quality images. Scale: The image gets drawn downscaled or upscaled. ![]() This should be used instead of scale when the image is much larger than the view. Resize: A software operation which changes the encoded image in memory before it gets decoded. Defaults to auto.Īuto: Use heuristics to pick between resize and scale. ![]() If you want to closely examine any one of the GIF frames, you can disable the animation and specify the frame number you're interested in.The mechanism that should be used to resize the image when the image's dimensions differ from the image view's dimensions. In the options, you can also find a section about GIF frame delays, frame sizes, and frame counts. The "Animation Preview" option lets you see the input GIF with the original background and the output GIF with the removed background. This option works only in the browser and illuminates the removal areas using black and white pixels. To see exactly which pixels will be removed and which will remain, you can use the "Alpha Channel Preview" option. For example, the percentage 0% means match just one color and 20% means match 20% of similar color tonality. In this option, you can specify the percentage from 0% to 100%. If the background of your animation has various shades of the same color, you can remove them as well via the shade matching option. Similarly, if you enter a mathematical color value "#0000ff", the program will remove all blue pixels. For example, if you enter the color "yellow", the program will remove the yellow background from the animation. The area that will be removed from the GIF is selected by matching the specified color in pixels of the frames. When the background is deleted, you can download the transparent GIF right away. If your GIF has a single frame (it's static), then it deletes the background from just this one frame. If your GIF is multi-frame (it's animated), then it loops over all frames and deletes the background from every frame. This is a browser-based program that deletes the background color from all GIF frames.
