Edip
support :ref:`normally <always-supported-filetypes>` following images files formats to load into the program for processing:
- bmp, dib (bitmap image file.)
- jpg, jpeg, jpe (Join photographic Expert Group.)
- png (Protable Network Graphics.)
- tiff, tif (Tag(ged) Image File (Format).)
- ras, sr (Sun Raster).
- pbm, pgm, ppm (Portable Image Format.)
- webp.
The image file is loaded into the program and converted into RGB, (internally BGR) format or RGBA (internally BGRA) if an alpha channel is available in the image.
Note
For supporting an image filetype the required library need to be installed except for:
- bmp, dib (bitmap image file.)
- pbm, pgm, ppm (Portable Image Format.)
- ras, sr (Sun Raster).
Which are always supported.
You can load an image file to process it into
Edip
by clicking on the :guilabel:`Open` button in the buttonbar,through the menu item :menuselection:`Files --> Open file` or by hitting the shortcut Ctrl + O.
You can start the program with am image file path as argument:
$ edip image_filepathYou can open an recent image file by using the menu item :menuselection:`Files --> Recent files`.
You can save an image file by pressing the button :guilabel:`Save` in the button bar,
trough the menu item :menuselection:`Files --> Save file` or by hitting the shortcut Ctrl + S.
Then you can set the output size of the image which default to the originally image size.
And setting some options in relatinship to the format if available.
Compression: from level from 0 to 9. A higher value means a smaller size and longer compression time. Default value is 3.
Strategy:
- Default.
- Filtered.
- Huffman only.
- RLE.
- Fixed.
Bilevel:
You can only store an image as bilevel if the image is a :ref:`binary <binary-images>` (black and white) image.
Otherwise the result will be undefined.
- Quality: it can be a quality from 0 to 100 (the higher is the better). Default value is 95.
- Features:
- Progressiv (disabled per default).
- Optimize (disabled per default).
- RST Restart: JPEG restart interval, 0 - 65535, default is 0 - no restart.
- LUMA quality: Separate luma quality level, 0 - 100, default is 0 - don't use.
- CHROMA quality: Separate chroma quality level, 0 - 100, default is 0 - don't use.
- Binary: For PPM, PGM, or PBM, it can be a binary format flag, 0 or 1. Default value is 1.
- Quality: For WEBP, it can be a quality from 1 to 100 (the higher is the better). By default and for quality above 100 the lossless compression is used.
