Computer graphics in the browser
Computer graphics is part of the Polish computer science curriculum from grade 4 to high school: illustrations, photo editing, logos and posters, simple animations, and later color models, file formats and compression. In BitWizards all three editors run in the browser: a Paint-style raster editor, a vector editor with objects, and frame-by-frame animation with GIF export. Nothing to install, and the finished file can be downloaded.
Primary school course - High school and technical school course (both in Polish)
Three editors
- Raster graphics: pencil, brush, highlighter, airbrush and eraser, lines and shapes, fill, text, color picker, selection with copy, flip and rotate, filters (grayscale, negative, sepia, brightness, contrast, blur) and up to 10 layers. Saves as PNG or JPG.
- Vector graphics: rectangle, ellipse, line, triangle, star, polygon, freehand line and text; fill, stroke, opacity, rotation, groups, order, alignment, equal spacing and flips. Saves as SVG or PNG.
- Animation: frames drawn in the vector editor with the previous frame shown underneath, playback at 1-30 frames per second and GIF export.
Two courses following the curriculum
Primary school (grades 4-8, 10 topics): first drawing, shapes and fill, text on an image, selection and flips, layers and filters, vector graphics, composition, logo and poster, frame-by-frame animation and file formats.
High school and technical school (9 topics): raster and vector, the RGB model and hex notation, retouching, layers, a logo and an icon set, a floor plan as a 2D model, an infographic, animation timing, and file formats with lossy and lossless compression.
The same topics appear in the year-long class courses for grades 4-8, high school grade 3, technical school grade 2 and the extended level (all in Polish), together with 3D solids drawn by a Python program.
For teachers
- Your own tasks: build the starting image in the editor and the checking rule in a wizard tested against the model solution.
- The student’s work is stored as a list of actions, so the replay shows every step, and live view works during the lesson.
- My documents: drawings, vector graphics and animations outside the courses, also for group work.
