 {{:image_archive:filter:icc.png?nolink }} ICC color profiles are based on a vendor-independent standard by the International Color Consortium and define distinct color spaces for individual devices, such as monitors and printers.  This assures printed output will match the appearance on your monitor, assuming the devices support ICC color profiles. To manage the ICC color profile associated with an image, select the image and open the “ICC Color Profile” pre-processing tool from the image toolbox. {{:image_archive:filter:icc.png?nolink }} ICC color profiles are based on a vendor-independent standard by the International Color Consortium and define distinct color spaces for individual devices, such as monitors and printers.  This assures printed output will match the appearance on your monitor, assuming the devices support ICC color profiles.

 StudioLine does allow you to permanently reduce the pixel size of original  images.  This may be useful if you scanned an original in better resolution than you ever expect to need.  You should keep in mind, however, that both print and internet technology keeps advancing with disk storage becoming increasingly affordable.  In a few years you could find yourself scrambling for that original size, which may have seemed excessive today. StudioLine does allow you to permanently reduce the pixel size of original  images.  This may be useful if you scanned an original in better resolution than you ever expect to need.  You should keep in mind, however, that both print and internet technology keeps advancing with disk storage becoming increasingly affordable.  In a few years you could find yourself scrambling for that original size, which may have seemed excessive today.

 The “Image Size” drop-down menu offers a variety of options, including common standard sizes.  The choice “Use Original Image Size” will retain the current size when using this window to convert between graphics formats instead (for example from TIFF to JPEG). The “Image Size” drop-down menu offers a variety of options, including common standard sizes.  The choice “Use Original Image Size” will retain the current size when using this window to convert between graphics formats instead (for example from TIFF to JPEG).
  
-“Custom” activates the width and height controls to define any custom size.  The standard or custom size you choose defines a bounding rectangle into which StudioLine will proportionally scale the images.  Consequently, one side of the resized image (unless it’s a square) will be smaller than the chosen “Maximum Size,” if the selected width/height proportions do not match the image’s proportions.  Enlarging images produces poor image quality and is therefore not recommended.+“Custom” activates the width and height controls to define any custom size.  The standard or custom size you choose defines a bounding rectangle into which StudioLine will proportionally scale the images.  Consequently, one side of the resized image (unless it’s a square) will be smaller than the chosen “Maximum Size”, if the selected width/height proportions do not match the image’s proportions.

-The option “Automatically Adapt to Orientation,” keeps your portrait orientation images portrait, and your landscape orientation landscape.  Let us say you specify an image size of 640x480 pixels, then a portrait orientation image will be 640 pixels high, whereas a landscape orientation image will be 640 pixels wide.  The long side will always receive the larger amount of pixels.  This saves a lot of extra steps and headaches.+The option “Automatically Adapt to Orientation” keeps your portrait orientation images portrait, and your landscape orientation landscape.

 Next to the image size input fields, you can choose the unit of measurement as pixels, inches, or centimeters.  That is helpful if images are later emailed to be printed at a given paper size.  The field “DPI” will let you control the print resolution. Next to the image size input fields, you can choose the unit of measurement as pixels, inches, or centimeters.  That is helpful if images are later emailed to be printed at a given paper size.  The field “DPI” will let you control the print resolution.

-Near the bottom of the panel you select the file format.  The default is “JPEG,” which uses a very effective compression algorithm to reduce file size while retaining optimum image quality.  JPEG format gives you the further option to customize image quality and file size as you need it.  The higher the quality, the more memory space the file will use.  The lower the file size, the lower the image quality, the quicker the image will load on a web page or in an email.+Near the bottom of the panel you select the file format.  The default is “JPEG”, which uses a very effective compression algorithm to reduce file size while retaining optimum image quality.
