How to create a perfectly measured border?

Method 1:

• First enable the Rulers in Galaincha Working area. (View->Rulers)
• Now set the unit of measurement either in Inches or in Centimeters but avoid pixels.  (View->Units-> Inches / Centimeters)
• Create a new file with all the necessary inputs (Size, Resolution). Make sure that the resolution is same as the file you are working on
• Set the size square in area (e.g. 25 cm width / 25 cm height)
• Next fill the entire canvas with different color.

• Now, select the entire canvas (Ctrl + A), copy it and paste it into the file in which you want to add the border
• (The pasted element will stick on the top left corner of the canvas. This will be the reference block for creating the border.)
• Select the Border Tool and draw the border based on the reference

Method 2:

• First enable the Rulers in Galaincha Working area. (View >> Rulers)
• Now set the unit of measurement either in Inches or in Centimeters but avoid pixels.  (View >> Inches / Centimeters)
• Select the Border Tool
• Hover the mouse in canvas to check the border measurement in Ruler, both vertically and horizontally

Once the measurement is set, start drawing the border.
