Projects, Artworks and Filenames
A project is a set of configuration settings ( There are many possible settings ! )
If you work on different GLCD projects, you can save the “current” settings inside a Project name. It’s the easiest and fastest way to switch from one to another.
A so called “artwork” is a set of files related to the graphic filename : In the below example a graphic saved for example as NewBitmap.BMP , will be converted to an output file called NewBitmap.h , and the associated touch panel file will then be named NewBitmap.TSC (Red Arrow)
When you save your “artwork” AS (yellow arrow), as a bitmap, you will change the basic filenames
Load a graphic
- You can either use the direct graphic load by dialog located at the top of main menu File
- switch to the file explorer / or click Load graphic File in main menu File (fig1. red arrow)
- In the list of files, click to select your particular graphic file you want to load (fig1 blue arrow) , it appears in the graphics viewer window at the right side.
- Resize or turn/tilt the preview image using the buttons located at the top of the graphic preview.
- Double click in the graphics viewer (yellow arrow) or the click the import button located at the top or bottom of the preview (fig1. Green arrow)

If the graphic is larger than the Work Canvas a message box will ask you if you want resize the image to fit the canvas or not.
The graphic will be imported in the selection layer , not directly into the Work Canvas (fig2. imagine your own graphic inside the canvas)
The red frame (fig2. red arrow) around the canvas means that you will have to paste the graphic into the canvas after moving it, convert it. When outline frame is red, it means that a “floating ” selection layer above the canvas is displayed…
The imported graphic can be moved around above the Work canvas : Move/drag the red frame to the desired canvas location with the left mouse button pressed. (fig2. blue arrows)
Then Paste the selection layer (fig2. green arrow) The red frame in the frame and around the work canvas dissapears. (There are also other ways to Paste, in menus, using the return key etc..)
