1. Open the vector graphic file in Inkscape (C:\School\image010101.svg).

2. Click on the blackboard picture to select it. Eight double-headed arrows will appear in a rectangle around the selection, as shown in the following image:

3. Drag-and-drop one of the diagonal double-headed arrows and scale the image both in the horizontal (X) and vertical (Y) directions. You can do it holding the Ctrl key down in order to maintain the original aspect ratio.

4. Next, click on the eraser picture to select it and enlarge it to match the blackboard's size.

5. Drag-and-drop the eraser to move it below the blackboard, as shown in the next screenshot:

6. Select File | Save, to save the changes made to the original Inkscape SVG file.

7. Select File | Export Bitmap. A dialog box showing many export options will appear. Enter 30 on the first dpi (Dots Per Inch) textbox.

8. Click on the Drawing button, and then on Export. Inkscape will export the drawing in PNG (Portable Network Graphics) format. The exported bitmap graphics with a big blackboard and a big eraser will be saved in C:\School\image010101.png.

9. Next, open the other vector graphic file in Inkscape (C:\School\image010102.svg).

10. Repeat the aforementioned steps (2 to 7) to export a new bitmap graphic with a big case and a pair of big scissors, as shown in the next screenshot. The exported bitmap graphic will be C:\School\image010102.png.

11. Click on the case picture to select it and shrink it.

12. Click on the scissors picture to select it and shrink it to match the new smaller case's size.

13. Drag-and-drop the scissors to move them below the case, as shown in the next screenshot:

14. Select File | Save As, to save the new manipulated vector graphic with a new name. Enter image010103 as the new name and click on the Save button.

15. Select File | Export Bitmap. A dialog box showing many export options will appear. Click on the Drawing button, and then on Export. Inkscape will export the edited drawing in PNG format. The exported bitmap graphics file with a small case and a pair of small scissors will be C:\School\image010103.png.

16. Next open the previously manipulated vector graphic file in Inkscape (C:\School\image010101.svg).

17. Repeat the aforementioned steps (11 to 15) to edit the vector graphic and export a new bitmap with a small blackboard and a small eraser, as shown in the next image. Use image010104 as the new Inkscape file. Thus, the new exported bitmap graphic will be C:\School\image010104.png.
