Classes

ApiFiles
Provides API for working with files
ApiGroups
Provides API for working with groups
ApiUpload
Provides API for uploading files [...]
ApiVideoEncoding
Provides API for working with video encoding
ArchiveTransformation
Gets a group as an archive: ArchiveTValue
AuthScheme
To authenticate your account, every request made to https://api.uploadcare.com/ MUST be signed. There are two available auth schemes: a simple one with intuitive auth-param and a more sophisticated and secure one that can be used for Signed Requests.
AuthSchemeRegular
Provides Uploadcare (regular) auth scheme
AuthSchemeSimple
Provides Uploadcare.Simple auth scheme
AutoRotateTransformation
Instruct Uploadcare CDN whether it should rotate an image according to the EXIF orientation tag or not.
BlurTransformation
Blur images by the strength factor. The filtering mode is Gaussian Blur, where strength parameter sets the blur radius — effect intensity. Technically, strength controls the Gaussian Blur standard deviation multiplied by ten. Note, different strength values do not affect the operation performance. value should be in 0..5000 range
BooleanTransformation
An abstraction to make transformation implementation with bool values which transforms to yes/no string
CancelToken
Provides cancel mechanism to upload process [...]
CdnFile
Provides a simple way to work with Transformation
CdnGroup
Provides a simple way to work with GroupTransformation
CdnImage
Provides a simple way to work with ImageTransformation
ClientOptions
Uploadcare client options
CndEntity
CropTransformation
Crop an image to fit into specified dimensions, implement optional offsets.
CutTransformation
Cuts out a video fragment based on the following parameters: start, length [...]
Dimensions
dart:ui Size replacement for non flutter project
EnhanceTransformation
Auto-enhance an image by performing the following operations: auto levels, auto contrast, and saturation sharpening. value should be in 0..100 range
EnumTransformation<T>
An abstraction to make transformation implementation with enum values
FaceRect
Provides uploadcare face shape
FacesEntity
Base object to hold Face Recognition data of an image
FileInfoEntity
Base object to hold Uploadcare file data
FilesOrdering
Provides a way to order files
FlipTransformation
Flip an image (mirror-reverse an image across the horizontal axis).
GifToVideoTransformation
GIF to Video conversion that provides better loading times thus reducing your bounce rate. The feature is available on paid plans only. Converts GIF files to video on the fly. You can change output format with VideoFormatTransformation and change video quality with QualityTransformation [...]
GrayscaleTransformation
Desaturate an image.
GroupInfoEntity
Groups are identified in a way similar to individual files. A group ID consists of a UUID followed by a ~ tilde character and a group size: integer number of files in group. For example, here is an identifier for a group holding 12 files, badfc9f7-f88f-4921-9cc0-22e2c08aa2da~12
GroupTransformation
An abstraction for group transformations
ImageFormatTransformation
Convert an image to one of the supported output formats: ImageFormatTValue
ImageResizeTransformation
Resize an image to fit into specified dimensions.
ImageTransformation
An abstraction for image transformations
IntTransformation
An abstraction to make transformation implementation with int values
InvertTransformation
Invert the colors of an image.
ListEntity<T>
When you get a collection in a response, like with getting a list of files, it is paginated. That is, items in the collection are returned in batches. Every returned batch object is ListEntity instance
MaxIccSizeTransformation
Strip off an ICC profile from an image based on the profile value in kilobytes. value should be positive int
MirrorTransformation
Mirror an image (mirror-reverse an image across the vertical axis).
NullParamTransformation
An abstraction to make transformation implementation with no parameters
Offsets
dart:ui Offset replacement for non flutter project
OverlayCoordinates
OverlayTransformation
The overlay operation allows to layer images one over another. [...]
PreviewTransformation
Resize an image to fit into specified dimensions, proportional.
ProgressEntity
An object that represents progress data
ProgressiveTransformation
Convert JPEG to Progressive JPEG. Has no effect on non-JPEGs. Does not force image formats to jpeg. if value is equal true then are using multi-scan rendering.
QualityTransformation
Sets the level of source quality that affects file sizes and hence loading times and volumes of generated traffic.
ResizeTransformation
Base class for resize-related transformations
RotateTransformation
Rotate an image counterclockwise. value should be in -360..360 range
ScaleCropTransformation
Downscale an image along one of the axes (the one with smaller linear size) and crop the rest. The method can be implemented with manual, center-focused or “smart crop” behavior.
SetFillTransformation
Set the fill color when converting alpha channel enabled images to JPEG, with CropTransformation or StretchTransformation.
SharedFile
Base class which describes cross-platform file implementation
SharpTransformation
Sharpen an image, might be especially useful with images that were subjected to downscaling. value should be in 0..20 range
StretchTransformation
Set the ImageResizeTransformation behavior when provided Size are greater than the source image dimensions. The directive should come before ImageResizeTransformation transformation to give any effect.
Transformation
Base class for accessing the Uploadcare CDN API
UploadcareClient
Provides centralized access to Uploadcare API [...]
UploadcareImageProvider
Constructs right Uploadcare CND url by id and provided transformations if any [...]
UrlUploadStatusEntity
Provides status data from fromUrl uploading
VideoEncodingConvertEntity
Provides response data from convert job
VideoEncodingJobEntity
Provides status data for converting job
VideoEncodingResultEntity
Provides converting result data
VideoFormatTransformation
Converts a file to one of the HTML5 video formats: VideoFormatTValue
VideoResizeTransformation
Resizes a video to the specified dimensions. The operation follows the behavior specified by one of the four presets: VideoResizeTValue
VideoThumbsGenerateTransformation
Creates N thumbnails for your video, where N is a non-zero integer ranging from 1 to 50; defaults to 1. [...]
VideoTransformation
An abstraction for video transformations
