A Vector Image is a representation of an image as an array of pixels, the images are often photographic.
Computer monitors are made of up tiny rectangular cells called pixels and images are constructed from these tiny cells. The size and distance of the cell from each other determines the quality of the images produced – the smaller and closer, the better onlineconvert. This in essence increases the size of files needed to store the data.
When images are magnified and the number of pixels is kept the same, the number of each pixel grows therefore, causing the image to become pixilated when viewed with the eyes. This means that a small picture becomes grainy when it is zoomed out or the resolution is increased beyond a certain threshold.
Designers convert jpg to vector to eliminate this problem. Vector graphics stores the shapes, line and color that make up an image as a mathematical formula. Hence, when enlarging the image, the vector program recreates the image using this formula thereby creating the best possible screen image with the given screen resolution.
This means that since the vector program recreates the image using mathematical formulae, it can scale the image to any size as long as the screen resolution permits it. Printing such images to paper gives a much sharper and clearer image with higher resolution than what shows on the screen.
The software to convert jpg files to vector is usually very expensive. The much less expensive ones have limited color reproduction capacity.
To convert jpg to vector with unlimited color capacity, open-source software might be the solution. Follow the steps carefully.
1. Browse for an open source vector imaging software called Inkscape.
2. Click the download link and run the program to install it on your computer.
3. After installation, click ‘Open Program’. Not much advanced knowledge is needed to use this program as it is very user-friendly.
4. Select ‘File’ from the drop-down menu bar at the top and, select ‘Import’. Choose the Jpg file you need to convert and proceed.
5. From the drop-down menu bar, select ‘Path’ and then ‘Trace Bitmap’. This action opens another window to adjust settings and there is a preview of the changes on the right.
6. Select the ‘Colours’ option and increase the number of ‘Scans’ several times
7. Click on the ‘Update’ menu. Increasing the number of scans increases the resolution, the file size and the speed at which the document will render. Play around with the settings to suit your image requirements and update it regularly.
8. Save the image as an.eps file and your jpg image is now vector!
