Zinc, an image processor written in C
- GrayScale
- Avarage
- Luminosity
- Lightness
- Brightness adjustment
- Tinting
- Inverting colors
- Cropping
- Without changing the resolution
- Changing the resolution
If you are using Windows you do have to use mingw32 or mingw64. On Mac & Linux you should install the "gcc" package. Then you can run:
$ make # exe will be generated in the projects root directory.
$ make install # if you would like it to be globally accessible.
$ make uninstall # uninstall zinc.run ./zinc --help for more information. For ease of use here is the output:
Pattern:
for Linux & Mac:
./zinc [Options] [Image]
for Windows:
zinc [Options] [Image]
Note:
You have to give the parameters after function call.
You neigther have to put <> brackets nor commas when <r,g,b> or <x,y> is specified.
Just put values and spaces between the parameters.
Example: 0.43 0.654 0.12 (r,g,b example)
425 645 (x,y example).
Lastly I used factors instead of percentages. As it's more accurate.
Example: for brightness, setting factor to 2.0 will double the brightness.
for tinting, changing the r value to 1.5 will increase half of the red value.
Options:
-v, --version check the version of zinc.
-h, --help show this help message.
-o, --output choose a name for the output file.
-g, --gray turn an image gray.
-gl, --gray-lumin turn the image gray with rgb values that fits human eyes.
-gli, --gray-light turn the image gray with min,max values.
-ti, --tint <r,g,b> tint the image with the <r,g,b> values.
-br, --brightness <factor> change the brightness depending on the percentage.
-in --invert invert the colors of the image.
-cwctr, --cropwctr <x1,y1> <x2,y2> <r,g,b> crop the image without changing the resolution.
x1,y1 = top left coordinate. x2,y2 = bottom right coordinate.
r,g,b = color for the uncropped areas.
-cctr, --cropctr <x1,y1> <x2,y2> crop the image and change the resolution.
x1,y1 = top left coordinate.
x2,y2 = bottom right coordinate.
-th, --threshold <intensity> turns the image black and white depending on the threshold.
<intensity> ranges from 0 to 255.
