ImgConverter – Example
Usage
ImgConvert version 1.0 BETA [Windows 64-bit] (2017.12.29)
Usage: imgconvert.exe InputFile(s) [-o FILE] [-f EXT] [-od DIR] [-r[=X]] [-op STR] [-os STR] [-sld] [-slf] [-fs] [-lf[=FILE]] [-lfm MODE] [-pngcl X] [-bmprle=[y|n|auto]] [-jpgq X] [-jpgp] [-rs VAL] [-rsf FLT] [-if FMT] [-cc X] [-b X] [-c X] [-g X] [-gr X] [-gg X] [-gb X] [-cr X] [-cg X] [-cb X] [-ca X] [-gs] [-ic] [-fv] [-fh] [rt X] [-i] [-h] [-V] [--home] [-- InputFile(s)]
Mandatory arguments to long options are mandatory for short options too.
Options are case-sensitive. Values are case insensitive.
Options and values enclosed in square brackets are optional.
Options and input files can be placed in any order, but — (double dash) indicates the end of parsing options and all subsequent parameters are treated as filenames.
——————————————————————————–
If the option value is a negative number, you must use the “=” sign.
For example, to set the contrast to -10 you must use: -c=-10, NOT a -c -10

| -slf, –file-symlink | Accept symbolic links to files when searching for files. |
| -fs, –force-save | Forces the saving of the target file, even if no operation has been performed on the source image. |
| -pngcl, –png-compression-level=X |
PNG compression level. Integer in range 0..9 (0 – no compression, 9 – best compression). |
| -bmprle, –bitmap-RLE=[y|n|auto] | Use RLE compression in bitmaps. y – use RLE, n – dont use RLE, auto – detect best option. Default: auto |
| -jpgq, –jpeg-quality=X | JPEG quality. Integer in range 1..100 (1 – the worst, 100 – best qaulity) |

Resize values
W and H must be positive integers, optionally terminated by the % sign.
WxH– The size of the image will be W pixels (width) per H pixels (height).0xH– The width of the image will be calculated automatically maintaining the original proportions.Wx0– The height of the image will be calculated automatically maintaining the original proportions.W– As above.W%– The width of the image will be W percent of the width of the source image. The height of the image will be calculated automatically maintaining the original proportions.0xH%– The height of the image will be H percent of the height of the source image. The width of the image will be calculated automatically maintaining the original proportions.W%xH%– The width of the image will be W percent of the width of the source image. The height of the image will be H percent of the height of the source image.
