Syntax

utils.convertTifToJpg(Long tifDirId,String tifFileName,Long jpgDirId,String jpgFileName,Float compressionFactor);

Details

tifDirId - folder identifier, where the input TIFF imagefile is already stored 
tifFileName -TIFF image file name, stored in the folder identified by tifDirId 
jpgDirId- folder identifier, where the JPEG image will be saved 
jpgFileName- file name for the JPEG image to create

Scale a jpg image, using width & height

Create an image jpg file, starting from an already existing jpg image file and scale it, using a new width x height.

Syntax:

  utils.scaleJpgFile(
    Long srcJpgDirId,
    String srcJpgFileName,
    Long destDirId,
    String destFileName,
    Long maxWidth, 
    Long maxHeight
  );

srcJpgDirId	directory id where the already existing jpg image file has been stored
srcJpgFileName	already existing jpg file name
destDirId	directory id where creating a new scaled jpg image
destFileName	jpg file name to create, generated starting from the source image
maxWidth	new image width
maxHeight	new image height

Scale a jpg image, using a scale

Create an image jpg file, starting from an already existing jpg image file and scale it, using a scale to reduce/enlarge it.

Syntax:

  utils.scaleJpgFile(
    Long srcJpgDirId,
    String srcJpgFileName,
    Long destDirId,
    String destFileName,
    Double scale
  );

srcJpgDirId	directory id where the already existing jpg image file has been stored
srcJpgFileName	already existing jpg file name
destDirId	directory id where creating a new scaled jpg image
destFileName	jpg file name to create, generated starting from the source image
scale	scale ratio
