- 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.
-
