Functions

  • GetReadableImageFormats Returns a list of image formats that Lucee can read on the operating system where Lucee is deployed.
  • GetWriteableImageFormats Returns a list of image formats that Lucee can write on the operating system where Lucee is deployed.
  • ImageAddBorder Adds a rectangular border around the outside edge of a image.
  • ImageBlur Smooths image.
  • ImageClearRect Clears the specified rectangle by filling it with the background color of the current drawing surface.
  • ImageCopy Copies a rectangular area of an image.
  • ImageCrop Crops a image to a specified rectangular area.
  • ImageDrawArc Draws a circular or elliptical arc.
  • ImageDrawBeveledRect Draws a rectangle with beveled edges.
  • ImageDrawCubicCurve Draws a cubic curve.
  • ImageDrawImage this function is deprecated, use ImagePaste instead. Draws a image on a image with the baseline of the first character positioned at (x,y) in the image.
  • ImageDrawLine Draws a single line defined by two sets of x and y coordinates on a image.
  • ImageDrawLines Draws a sequence of connected lines defined by arrays of x and y coordinates.
  • ImageDrawOval Draws an oval.
  • ImageDrawPoint Draws a point at the specified (x,y) coordinate.
  • ImageDrawQuadraticCurve Draws a curved line. The curve is controlled by a single point.
  • ImageDrawRect Draws a rectangle.
  • ImageDrawRoundRect Draws a rectangle with rounded corners.
  • ImageDrawText Draws a text string on a image with the baseline of the first character positioned at (x,y) in the image.
  • ImageFilter the function ImageFilter allows to execute a filter against a image.
  • ImageFilterColorMap These are passed to the function ImageFilters (see ImageFilter documentation) which convert gray values to colors.
  • ImageFilterCurves the curves for the wrap grid
  • ImageFilterKernel These are passed to the function ImageFilters
  • ImageFilterWarpGrid A warp grid. These are passed to the function ImageFilters (see ImageFilter documentation).
  • ImageFlip Flips an image across an axis.
  • ImageFonts return all available
  • ImageFormats return all available readers and writers
  • ImageGetBlob Retrieves the bytes of the underlying image. The bytes are in the same image format as the source image.
  • ImageGetBufferedImage Returns the java.awt.BufferedImage object underlying the current image.
  • ImageGetEXIFMetadata Retrieves the Exchangeable Image File Format (EXIF) headers in an image as a CFML structure.
  • ImageGetEXIFTag Retrieves the specified EXIF tag in an image.
  • ImageGetHeight Retrieves the height of the image in pixels.
  • ImageGetIPTCTag Retrieves the value of the IPTC tag for a image.
  • ImageGetWidth Retrieves the width of the specified image.
  • ImageGrayscale Converts a image to grayscale.
  • ImageInfo Returns a structure that contains information about the image, such as height, width, color model, size, and filename.
  • ImageNegative Inverts the pixel values of a image.
  • ImageNew Creates a image.
  • ImageOverlay Reads two source images and overlays the second source image on the first source image.
  • ImagePaste Takes two images and an (x,y) coordinate and draws the second image over the first image with the upper-left corner at coordinate (x,y).
  • ImageRead Reads the source pathname or URL and creates a image.
  • ImageReadBase64 Creates a image from a Base64 string.
  • ImageResize Resizes a image.
  • ImageRotate Rotates a image at a specified point by a specified angle.
  • ImageRotateDrawingAxis Rotates all subsequent drawing on a image at a specified point by a specified angle.
  • ImageScaleToFit Creates a resized image with the aspect ratio maintained.
  • ImageSetAntialiasing Switches antialiasing on or off in rendered graphics.
  • ImageSetBackgroundColor Sets the background color for the image. The background color is used for clearing a region. Setting the background color only affects the subsequent ImageClearRect calls
  • ImageSetDrawingAlpha Sets the current drawing alpha for images. All subsequent graphics operations use the specified alpha.
  • ImageSetDrawingColor Sets the current drawing color for images. All subsequent graphics operations use the specified color.
  • ImageSetDrawingStroke Sets the drawing stroke for points and lines in subsequent images.
  • ImageSetDrawingTransparency Specifies the degree of transparency of drawing functions.
  • ImageSharpen Sharpens a image by using the unsharp mask filter.
  • ImageShear Shears an image either horizontally or vertically.
  • ImageShearDrawingAxis Shears the drawing canvas.
  • ImageTranslate Copies an image to a new location on the plane.
  • ImageTranslateDrawingAxis Translates the origin of the image context to the point (x,y) in the current coordinate system.
  • ImageWrite Writes a image to the specified filename or destination.
  • ImageWriteBase64 Writes Base64 images to the specified filename and destination.
  • ImageXORDrawingMode Sets the paint mode of the image to alternate between the image's current color and the new specified color.
  • IsImage Determines whether a variable returns a image.
  • IsImageFile Verifies whether an image file is valid.
