1. Description
- InstaCropper is an image processing utility that crops unneeded parts
of images, automatically. Its main function is to automatically crop
white backgrounds. This automatic cropping is available either
by the batch process or by the interactive method.
In the batch processing following order of the images are
processed: the images are chosen from the source directory,
the non-image areas are cropped, and finally the only true image areas
are saved into the files at the destination directory. (see section
2.3 below) In interactive mode you can selecte an image to be
cropped and previewed on a window, save the cropped image into a file,
use the noise filtering which means that the non-image areas with
small dots are automatically cropped, and filter the image via the
adjusting the filter size control button and the threshold
control button. (see section 2.2 below)
- Manual cropping allows users to rotate and crop an individual image
simply and easily by the manual method.
- InstaCropper supports JPG, BMP, TGA image file formats for input and
output.
- InstaCropper is freeware.
2. Usages and Instruction
2.1 General Interface
Main window of InstaCropper consists of four parts:
- Left part of the window -- is the harddisk drive and folder's
tree box where scanned image can be chosen for the crop.
- Upper right part of the window -- is the file list box for the
selected directory. It will display both the files and folders
at the selected directory level.
- Middle right part of the window -- is the cropping control box.
- Lower right part of the window -- is the two image views window box
that show side by side the original and preview of the cropped
image instantly as you adjust the controls in the control box.
2.2 Single Image Cropping
The single image cropping is started once you select from the folder's
tree box an image to work with. The original image and preview image
will be shown at the two image views window box(i.e., Lower right part of
the window).
You can use cropping control box to adjust the parameters for
the cropping. Once you are done with the cropping you can save
the cropped image into an image file.
2.3 Multiple Image Cropping
You can crop multiple images by the batch process.
In the batch process dialog box, you can choose Source Image Directory
and Output Image Directory. The Source Image Directory is a directory
original images are, while the Output Image Directory is where cropped
images will be saved.
When image file's prefix or postfix is selected and specified, either
the specified prefix or the postfix is added to the original file name
when the output files are created in the output folder.
When the subfolder option is checked, files in sub-folders are cropped
and Output directory will have the same sub-folders as the source
directory.
2.4 Manual Mode Image Cropping
In manual crop mode the original image is displayed can be rotated or
cropped. You can rotated the image by entering rotation angle or turning
a dial using the mouse. You can crop the image by selecting an area
with mouse, and then you can move or resize the area.
After rotation and cropping, you can save the image.

3. Cropping Options
3.1 Cropping Options
- Gray level threshold:
Distinguishes backgrounds from image area. The value ranges
between 1 and 255.
For example, if the gray level value is 200 then the pixels
with values over 200 are considered as background pixels
while the pixels smaller than or equal to 200 are considered
to be the true image pixels. Thus, the smaller gray value will
make darker pixels considered as background pixels.
- Noise filtering:
Filters the noises out of an image.
- Filter size:
This is the dimension of the filter matrix.
For example, the value 7 means 7 x 7 filter that will be
applied to the image. Usually the larger the dimension will
provide better filtering of an image. The size can be only
an odd number.
- Threshold:
This is the number of pixels in the filter matrix that determines
whether the center pixel is considered noise or true image pixel.
For example, if the threshold is 4 while the filter size is 3,
then the center pixel is considered true image pixel.
Image pixel means a pixel that was considered as part of an image
by the Gray level threshold.
3.2 Image Output Options
InstaCropper supports JPEG file (JPG), Windows Bitmap (BMP),
Targa (TGA) image formats.
You can select an output image format so that all the images are
saved into that format or let the output image format the same
as source image format.
