There are tools, colorspaces, +paint operations, filters and kpart-based user interface plugins. +It is intended to make layer types plugins, too. + +* Scriptable + +Krita is scriptable in Python and Ruby. The scripting is +compatible with using the PyQt/KDE and Korundum for adding +GUI items. + +* File + +Import: png, tiff, jpeg, dicom, xcf, psd (up to version 6, +from version 7 on, the photoshop file format is closed and it +is impossible to get the spec to implement support in a +free software application), gif, raw, bmp, xpm, targa, rgb, ico, +openEXR. + +Export: png, tiff, jpeg, dicom, xcf, psd (up to version 6, +from version 7 on, the photoshop file format is closed and it +is impossible to get the spec to implement support in a +free software application), gif, bmp, xpm, targa, rgb, openEXR. + +Embedded icc profiles and exif information are preserved on +export to supporting file formats. + +Krita's native file format stores icc and exif information. + +* Color models + +Krita uses lcms for a dependable color workflow using icc profiles +for importing, exporting, selecting paint colors, printing, +cutting and pasting. + +** 8 bit/channel rgb, cmyk, grayscale, wet watercolors +** 16 bit/channel rgb, cmyk, grayscale, l*a*b, xyz (xyz may be removed) +** "half" rgb +** 32 bit float rgb (HDR), lms +** Colors can be selected from a color wheel, rgb or grayscale sliders + or with a palette + +* Editing + +** Unlimited undo and redo +** Cut, copy and paste with conversion through icc profiles if necessary +** paste into a new image + +** Viewing + +** Use OpenGL for display when possible +** View fullscreen +** Multiple views on one image +** Rulers +** zooming +** show or hide all palette windows in one go +** palette windows position is kept between sessions +** When maximized, Krita is usable on a 1024x768 screen with all + palettes open. +** Permanently accurate histogram palette +** Exposure slider for HDR images +** Optional "greening-out" of inactive layers to assist with artistic + workflow. +** Bird's eyeview of image and zooming (not sure this will be done in time) + +* Images + +** mirror, shear, rotate and scale images +** change the size of the canvas +** change the resolution of the image +** convert images between colorspaces +** set image properties (name, comments, profile, resolution) +** Combine layers in different colorspaces. The bottom-most + layer determines the image colorspace. +** Separate the channels of an image into grayscale (8 or 16 bits) + layers or images. + +* Layers + +** Embed KOffice documents as layers into an image +** Group layers +** Adjustment layers (not sure whether this'll make it) +** Lock layers (tools and filters cannot change the layer, but not all + destructive operations are disabled yet) +** Make layers invisible +** Add and remove layers +** Change the position of layers in the layer stack +** Mirror, shear, rotate and scale layers +** Save layer as image +** Composite layers with supported composite options, like + over, in, out, atop, xor, plus, minus, add, subtract, diff, + mult, divide, dodge, burn, bumpmap, copy, copy one channel, + clear, dissolve, displace, darken, lighten, hue, saturation, value, + color, colorize, luminize, screen, overlay, erase. (Not all colorspaces + support all composite operations). +** Change layer properties like name, position, colorspace +** Create a drop shadow behind the layer +** View the histogram of a layer; 16 bits or wider images have zoomable + histograms +** Insert screenshot as layer + + +* Selections + +** Select by colorrange +** Feather selection +** Invert selection + +* Tools + +Throught the innovative paintOp plugin system, all painting tools +(brush, ellipse, line, etc.) can paint aliased, anti-aliased, +erase, airbrush and more. + +** paintbrush +** colorpicker +** duplicate +** ellipse +** anti-aliased bucket fill and selection fill with color, patterns + or gradients. +** gradient +** line +** layer or selection move +** canvas pan +** rectangle +** text +** zoom +** crop +** paint with filters (to be integrated in the paintop system) +** polygons +** polylines +** stars +** transform selection/layer +** select similar colors +** select by painting +** select contiguous areas +** select ellipse +** deselect by erasing +** select by painting outline +** select polygonal +** select rectangular + +* Filters + +Krita can multithread the operation of some filters. Krita's +filters can be previewed in the filter gallery. + +** Apply previous filter again +** bumpmap +** image restoration with cimg +** brightness/contrast +** color adjustment per channel +** autocontrast +** desaturate +** gaussian blur +** sharpen +** remove mean +** emboss (laplacian, all directions, horizontal, vertical, horizontal and +vertical) +** edge detection (top, right, bottom, left) +** custom convolution +** cubism (converts to 8 bit rgba and back) +** invert +** reduce noise (simple and with wavelets) +** oilpaint (converts to 8 bit rgba and back) +** pixelize (converts to 8 bit rgba and back) +** raindrops (converts to 8 bit rgba and back) +** round corners +** small tiles (converts to 8 bit rgba and back) +** sobel (converts to 8 bit rgba and back) + +* Paint operations + +Krita's paint operations are usable with all painting tools. + +PaintOps can support composite options, like +over, in, out, atop, xor, plus, minus, add, subtract, diff, +mult, divide, dodge, burn, bumpmap, copy, copy one channel, +clear, dissolve, displace, darken, lighten, hue, saturation, value, +color, colorize, luminize, screen, overlay, erase. (Not all colorspaces +support all composite operations). + +PaintOps can support opacity settings and use the pressure value +of a tablet. Tilt and rotation is not yet supported. + +** airbrush +** eraser +** anti-aliased brush +** convolve +** duplicate +** aliased brush (pen tool) +** smeary brush (not sure whether this will get finished in time) +** paint with a tablet stylus. The pressure sensitivity + characteristics can be set. + +* Brushes + +** gimp brush shapes. Support for colored and grayscale brushes and + pipe brushes. Support from Gimp parasites in brushes. +** custom brush shapes +** text brush shapes +** brushes created from layers or images. These brushes can be saved +** colored brushes can also be used as masks + +* Fills + +** gimp-style patterns +** gimp-style gradients +** custom gradients
