If you would like to add text to your pixlr project, the TYPE tool is what you will need to start with.
Click anywhere on your image. A New Layer will automatically be created. Type whatever you want. Your new layer will be labeled whatever text you type.
Edit your font, color and size.
At this point you can move your text wherever you would like on your canvas. However, you cannot use any of the transform tools or other editing tools because it is still a text format. You will need to RASTERIZE the layer.
go to "Layer" and down to "Rasterize Layer"
By Rasterizing a layer, it makes it into an editable layer versus a text layer. You can now use the transform, color adjustment and other editing tools.
**NOTE: be sure you are done typing any text before you rasterize. Once you do this you will no longer be able to edit the content of your text.
