- PResizer -

PResizer is a Windows7 compatible standalone program to convert picture file(s) easily.
It does NOT delete the original picture(s), but generates new one(s) with a selectable prefix or postfix.

Version 3.0 may seem to freeze while working.
Don't panic, it is only the window what is frozen, the work is still progressing...
Once done, the program will quit gracefully... I'll fix this in v4.0.

It can convert RGB_BMP, PM, PNG, RGB16, CRW, TIF, JPG, ICO and many more to JPEG.

Imagine you have a folder full with huge pictures ( taken by your latest 18+ MegaPixel camera ),
but you would like to email a few of them. Emailing pictures with 10MB+ is only asking for trouble
and the recipients of your email might not be happy looking at 3800x2000 images. Converting the
picture individually is quite a pain, so, why not automate it?! THUS PResize was born :

There are 1+3 files in the package:
  • PResizer.exe which is the program itself.
  • jpeg62.dll, libtiff3.dll and zlib1.dll which are system files needed.

    Extract these 4 files into a directory where you will be using PResizer from.
    ( I usually create a folder named C:\Program Files\PResizer and put these files there... )

    Let's begin the explanation on "how-to-use" :

    This is the dialog which should appear after you click on the PResizer.exe file :

    Width and Height set the size of the newly created picture(s).
    Leaving one of these numbers at 0 means we will keep the aspect ratio of the original picture.
    Setting BOTH of these numbers to 0 means no scaling will be done; the original size of the image will be kept.
    If you set BOTH of these parameters, pictures may get distorted unless you set BB:

    BB indicates, that the Width/Height parameters are only referring to a bounding box.
    PResize will keep the aspect ratio while making sure, that the resulting images fit
    intor the Width/Height defined box.

    JPEG Quality sets the quality ( thus the size as well ) of the newly created pictures.
    The higher this number, the better the quality and the bigger the file size will be.

    Max. File Size controls how big the resulting picture file size should be.
    This feature changes the JPEG Quality dynamically to find the set file size.

    Sharpening controls if there is sharpening applied after the scaling.
    0 value means no sharpening applied. 9 - hard, 17 - medium, 40 - very mild.

    Force Rotation forces the picture to be rotated by the set degrees.
    PResize automatically detects if the image has rotation information included ( most new cameras
    detect and store this - landscape or portrait mode ) and rotates the picture accordingly.

    Adjust Rotation Size is a parameter to control if the Width/Height parameters should be adjusted
    in case the picture was rotated. I recommend having this feature enabled ( have the box checked ).
    If you have a picture of 2000x1000 with a 90 rotation information, the result is going to be a 400x800 image
    if the feature is enabled, or 800x1600 if it is unchecked using the above Width=800 and Height=0 settings.

    Keep Timestamp is used to change the system time of the newly created file.
    The time will reflect when the photo was taken or when the original file was created.

    Create HTML if checked will create an index.html file to include references to all the created pictures.

    Pre/Postfix settings are used to determine how the new name of the resulting files will be
    generated. The Character will be appended to the beginning ( Prefix ) or to the end (Postfix)
    of the file name with an underscore. ( fe. picture.tif will become s_picture.jpg in the above case )

    Start will invoke a File Selection dialogbox, where you can select the file(s) to work with.

    If the Max. File Size parameter is non-zero ( to control the resulting picture file size ),
    the JPEG Quality will become disabled, as PResize will dynamically find the suitable
    JPEG Quality coefficient satisfying the requested picture size condition.
