Class: Image_Transform

Image_Transform::addBorder()
Image_Transform::addDropShadow()
Image_Transform::addText()
Methods to add to the driver classes in the future
Image_Transform::canvasResize()
Image_Transform::colorarray2colorhex()
Converts an array of RGB value into a #FFFFFF format color.
Image_Transform::colorhex2colorarray()
Converts a color string into an array of RGB values
Image_Transform::crop()
Crops an image
Image_Transform::display()
Outputs the image to standard output
Image_Transform::factory()
Creates a new Image_Transform object
Image_Transform::fit()
Fits the image in the specified box size
Image_Transform::fitOnCanvas()
This works as per fit, but creates the canvas of size $width x $height and positions the resized image on it, by default in the centre.
Image_Transform::fitX()
Fits the image in the specified width
Image_Transform::fitY()
Fits the image in the specified height
Image_Transform::flip()
Vertical mirroring
Image_Transform::free()
Releases resource
Image_Transform::gamma()
Corrects the gamma of an image
Image_Transform::getHandle()
Returns the image handle so that one can further try to manipulate the image
Image_Transform::getImageHeight()
Returns the image height
Image_Transform::getImageSize()
Returns the image size and extra format information
Image_Transform::getImageType()
Returns the type of the image being manipulated
Image_Transform::getImageWidth()
Returns the image width
Image_Transform::getMimeType()
Returns the MIME type of the image being manipulated
Image_Transform::getNewImageHeight()
Return new image Y
Image_Transform::getNewImageWidth()
Returns the new image width
Image_Transform::getTempDir()
Returns the temp directory according to either the TMP, TMPDIR, or TEMP env variables. If these are not set it will also check for the existence of /tmp, %WINDIR%\temp
Image_Transform::getTempFile()
Returns a temporary filename using tempnam() and the above getTmpDir() function.
Image_Transform::getWebSafeFormat()
This looks at the current image type and attempts to determine which
Image_Transform::grayscale()
Converts an image into greyscale colors
Image_Transform::greyscale()
Converts an image into greyscale colors
Image_Transform::intersects()
Checks if the rectangle passed intersects with the current image
Image_Transform::isError()
Returns/sets an error when the instance couldn't initialize properly
Image_Transform::keepSettingsOnSave()
Image_Transform::load()
Loads an image file to work with
Image_Transform::mirror()
Horizontal mirroring
Image_Transform::normalize()
Normalizes the colors, gamma and other properties of an image (this should give a result equivalent to a Photoshop autolevels)

Resizes the image in the X and/or Y direction(s)
Image_Transform::rotate()
Rotates the image clockwise
Image_Transform::save()
Saves image to file
Image_Transform::scale()
Scales an image by a percentage, factor or a given length
Image_Transform::scaleByFactor()
Scales an image to a factor of its original size. For example, if my image was 640x480 and I called scaleByFactor(0.5) then the image would be resized to 320x240.
Image_Transform::scaleByLength()
Alias for scaleMaxLength
Image_Transform::scaleByPercentage()
Scales an image to a percentage of its original size. For example, if my image was 640x480 and I called scaleByPercentage(10) then the image would be resized to 64x48

Scales the image to the specified width
Image_Transform::scaleByXY()
Alias for resize()
Image_Transform::scaleByY()
Scales the image to the specified height.
Image_Transform::scaleMaxLength()
Scales an image so that the longest side has the specified dimension.
Image_Transform::setOption()
Sets one options
Image_Transform::setOptions()
Sets multiple options at once
Image_Transform::supportsType()
Returns if the driver supports a given image type
Image_Transform::_convert_image_type()
Returns the matching IMAGETYPE_* constant for a given image type
Image_Transform::_getColor()
Returns a color option
Image_Transform::_getOption()
Returns an option
Image_Transform::_get_default_text_params()
Returns the current value of $this->default_text_params.
Image_Transform::_get_image_details()
Sets the image type (in lowercase letters), the image height and width.
Image_Transform::_parse_size()
Parses input for number format and convert
Image_Transform::_prepare_cmd()
Handles space in path and Windows/UNIX difference
Image_Transform::_resize()
Place holder for the real resize method used by extended methods to do the resizing
Image_Transform::_rotation_angle()
Returns an angle between 0 and 360 from any angle value
Image_Transform::_set_img_x()
Sets the image width
Image_Transform::_set_img_y()
Sets the image height
Image_Transform::_set_new_x()
Sets the new image width
Image_Transform::_set_new_y()
Sets the new image height
