The image adjust panel lets you retouch raster images (jpg, tif, psd, png, etc.), with color space RGB, inserted in a FitPlot document.
Thanks to the CoreImage technology you can do directly inside FitPlot your final touching before printing.
As I always do, I recommend to use professional image editors to get more control on your images, though these new FitPlot features do their work very good. Only raster images can be edited with this panel, so you cannot modify brightness, contrast, saturation etc. on PDF, EPS or PS files.
To activate the panel click on the button .
If you do not see that button, edit the toolbar clicking on the icon in the toolbar.
You can also show/hide the panel with the combination cmd-alt-i or with the window->show/hide image adjust palette menu.
Note: the original image is'nt in any way modified by the adjusting done inside FitPlot.
You can, however, save the adjusted image as tiff with the command "export single image as TIF", available also in the toolbar with this icon:
The image adjust panel
- The title bar shows the file name and the size in pixels (if a raster image is selected).
- Since FitPlot 6 an histogram of the current image (RGB & alpha channels) is showed in the image adjust panel.
- The color effects (CLUT) popup allows to modify the image according to different flavours also known as CLUT (color lookup tables).
You can see samples of all these effects at this page.
- The image Filters you can apply to a raster image are the canonical set brighness, contrast, saturation and the very useful exposure and tinte. You can control each value by a slider or a numerical input between the max and min values admitted.
- The neutral check box: the neutral value has no effect on the image. When a slider has moved from its default position, the checkbox is ON and that filter is applied. Click on the checkbox to reset it OFF (neutral value).
- Numerical value of a filter: while usually reflecting the numerical value of the slider, double clicking on this field, lets you to set manually the filter value (only values between min and max are admitted).
- Resolution: in this line we can watch the ratio resolution / dimension of a raster image, together with a qualitative judgement about it. The program judges "optimal" an image with at least 300dpi in the dimension to print.
Of course, when an image is enlarged, resolution decreases and viceversa.
The panel allows to keep an eye on the "quality" on an image and, if we want, just a double click on the resolution field to set it manually (the image will be resized consequently).
The usual check box is here too, as before, to reset the image to its original resolution.
- Reset push button. Reset the image to the original one, setting all filters to neutral value and the color space to the embedded one (see point 2).
- Copy the current image settings to apply the same to another image.
- Paste the previously copied settings to the current image.
