Introduction

GUI for the common used ImageMagick functionality for processing pictures.

Conversions

  • scaling/resize, but keep proportion,
  • crop, three method to select crop,
  • text annotation, inside or outside of picture (mems generator)
  • border around picture,
  • rotation,
  • black-white or sepia,
  • contrast inxrease/decrease or normalize or histogram stretching,
  • color normalize: auto-level or equalize,
  • mirroring picture: horizontal and vertical
  • adding logo image o picture.

Functionality:

  • processing JPG, PNG, SVG and TIF images,
  • conversion into JPG, PNG and TIF format,
  • processing copy of picture, originals are safe,
  • processing single file or whole directory,
  • make screenshots (Linux) or get picture from clipboard (Windows, MacOS)
  • display selected tools,
  • tools selection,
  • preview orignal and result,
  • resize custom (pixels or percent) or predefined: FullHD, 2k, 4k,
  • crop selection via click on preview or coordinates,
  • crop coordinates:
    • two corners (upper left and lower right),
    • upper left corner and width plus height,
    • gravity, width plus height plus offset,
  • text: color, font and size selection and position (absolute or gravity),
  • predefined rotation: 90, 180 and 270 degree or custom,
  • customized sepia,
  • equalize by channel,
  • contrast between -3 and +3,
  • customized contrast stretching,
  • histograms of original and result pictures,
  • fast file navigation: First, Prev, Next, Last,
  • own command editor,
  • own command can be composed from executed commands,
  • is possible to use other ImageMagick commands, eg. -gaussian-blur,
  • logging conversion and internal messages,
  • GraphickMagick is supported partialy.
  • fast navigation by <Home>, <End>, <PgUp>, <PgDn> keys.

How to use it

Basic operations

  • Select image file,
  • Buttons Previous, Next, First, End (or keys <Home>, <End>, <PgUp>, <PgDn>) will navigate between pictures in current directory,
  • Buttons Preview open picture in default browser

Perform single conversion

  • Select required conversion (eg. Scaling)
  • Select rotate angle eg. 90,
  • Click Execute

Perform multiple conversion in one time

  • Select required conversion (eg. Scaling and Border)
  • Select rotate angle eg. 90,
  • Type width of border, and choose a color,
  • Click Execute All to perform every selected conversions.

Przetwarzanie wszystkich plików w katalogu

  • Select one image from directory
  • Try conversions as described above
  • Select Folder,
  • Click Execute All to perform every selected conversions for every pictures in directory.

Make screenshots

Linux

  • Click button Screenshot,
  • Click (select) window for screenshot,
  • or Click and drag for selection rectangle for screenshot.

Windows, MacOS

  • Picture is grabbed from Clipboard,
  • Click button Clipboard to grab picture

Common

  • Taken picture appear in preview in FotoKilof.
  • Screenshot are automatically saved in directory $TMP/%Y-%m-%D, eg. /tmp/2020-12-26.
  • Result picture is saved in sudirectory FotoKilof.

Configuration

  • Button Save save current settings (from every tools) into file ~/.fotokilof.ini.
  • Button Load restore settings from file ~/.fotokilof.ini.
  • Configuration from file is read during every opening FotoKilof.

Picture conversion

Resize

Scaling/resize, but keep proportion. Resize can use custom or predefined values: FullHD, 2k, 4k. Percent means percent size of original picture.

Crop

Cut rectangular region of the image.

Crop methods:

  • two corners (upper-left and lower-right),
  • upper-left corner and width plus height,
  • gravity, width plus height plus offset.

Remember that upper-left coordinates of original picture are (0, 0).

Coordinates is possible to type in fields or select via click on preview.

Preview button will show crop rectangle on preview.

Text

Annotate an image with text. Is possible to choose color, font and size. Additionaly is possible to setup background with own color.

Coordinates are given as gravity plus offset or by select absolute pisition (select by left mouse button on preview).

Rotate

Predefined dvalues: 90, 180 and 270 degrees. In Custom comands is possible to type any degree.

Border

Surround the image with a border of color. Is possible to choose color and type width of border (in pixels).

Black-white/Sepia

Black-white

Convert image to grayscale

Sepia

simulate a sepia-toned photo.

Specify threshold as the percent threshold of the intensity (0 - 99.9%). Advice from ImageMagick documentation: a threshold of 80% is a good starting point for a reasonable tone.

Colors normalize

AutoLevel

Automagically adjust color levels of image

Equalize

Perform histogram equalization on the image channel-by-channel.

Contrast

Contrast

Enhance or reduce the image contrast. Range is beetween -3 and +3.

Contrast stretch

Increase the contrast in an image by stretching the range of intensity values.

Normalize

Increase the contrast in an image by stretching the range of intensity values.

Histogram

Histogram can be displayed on demand (because is time consumig)

Custom conversion

By execute conversion, command are written into Custom box, where we can build own conversion from pieces in own order with own parameters (e.g. rotation angle). Is possible to use almost all command of convert program (ImageMagick).
