TkzGeom is a GUI tool to create publication quality figures in .tex or .pdf format. It aids and speeds up the production of a wide range of tikz images.
Note that these demos are reduced in size and frame rate.
- TexLive 2019 or newer or MiKTeX 2019 or newer (have not tested MiKTeX but should work in principle), the program runs without it as long as auto-compile is turned off, and the project is never compiled but it results in user experience without visual feedback.
- A PDF to JPG converter, the default converter is
pdftocairo, which is part of TexLive. This can be configured in the settings menu. Gnuplot, this is needed only when functions are in the figure.- Libraries for Python can be installed using
pip install -r requirements.txt. Note that herePygmentsis not needed, only if the user wants to try other syntax highlighting than the built in.
- Run the
Makefileby running make in the root folder of the program. - From the radio button at the top of the screen choose the object type you would like to draw.
- In the corresponding droplist select the item to be added. Functions can be added on the separate click button.
- Click on the canvas or on existing objects.
- Once the object exists, "Right Click" the canvas and fine tune the appearance of the objects.
- Move the free points on the canvas or the canvas itself by choosing the "interactions" radio button. Zoom the canvas in/out using the slider on the right hand side.
- instantly generated TikZ code,
- move free points on the canvas,
- auto compilation into PDF for visual feedback,
- additional packages and libraries can be added,
- additional tikz code can be added after the generated code, so unimplemented features can be used on the user defined points, e.g. this can be used to define electric circuits with ease,
- additional code can be added before the image, this is useful e.g. for
\newcommands, - perfect tool for visualising figures in Euclidean geometry,
- projects can be saved, and loaded in the popular JSON extension, loading such file in a programming language with
openCVcan create animated videos.
Basic knowledge of tikz helps making the most out of this software.

point: click anywhere on the canvas; defines a point at any coordinate,
point on line: click segment or two points then enter ratio in a popup window; defines a point on a segment dividing it with a given ratio (can be any real number)
point on circle: click circle, then enter angle (in degrees) in a popup window; defines a point on a circle at specified angle to the abscissa
intersection: click four points (endpoints of segment 1 then endpoints of segment 2), or click two segments, or click a circle and a segment, or click a segment and a circle, or two points and a circle; defines the intersection of two lines, or a line and a circle, (in the latter case, two intersection points are possible), (circle-circle intersection is not yet implemented)
midpoint of segment: click two points or a segment; defines the middle points of a segment
midpoint of circle: click circle; defines the middle of a circle
orthogonal projection: click three points, or a segment and a point, or a point and a segment (the first two points define the segment, the last point to point to be projected); defines the orthogonal projection of a point onto a line
bisector: click three points (at the second point is the angle, the direction of angle matters); defines a point on the bisector of an angle
translate with vector: click three points: defines a new point from old after translation by vector
perpendicular: click two points; defines a point on the perpendicular to the segment at the first point
rotation: click two points and angle in degrees in a popup window; defines a point on rotated by a given angle around another point
make grid: click three points and rows and columns in a popup window (these points will span the grid); defines the lattice of points generated by the three selected points (movement of the three points results in the entire lattice move)
segment: click two points; defines a segment connecting the two points
polygon: click the vertices of the polygon and click the first vertex again to conclude selection; defines a polygon object
linestring: click the vertices of the linestring and the last vertex again to conclude; defines a linestring object
circumscribed circle: click three points; defines the circumscribed circle around three points
circle by its radius: click two points; defines a circle with first point as centre, the second point as a point on the perimeter
arc: click three points; defines an arc with first point as center, the other two defining the radius and range
sector: click three points; defines a sector with first point as center, the other two defining the radius and range
inscribed circle: click three points; defines the inscribed circle around three points
move point: drag free points the change their positions
move canvas: drag canvas to a new position
mark angle: click three points; defines an arc to show the presence of an angle
mark right angle: click three points; defines an arc to show the presence of a right angle
A select of features are included as part of the GUI, enough to cover most everyday situations, but does not aim to be comprehensive. To mitigate this issue, there is an option to add any code after the automatically generated code, and also to add other LaTeX packages/libraries. The draw order of objects is predetermined, there is no built in way to change this. (e.g. segments are always drawn above polygons.)
