Info

After they are inserted, bitmaps are converted to the Visual Components internal color palette. However, this may cause color distortions if, for example, many shades of the same color are used. A red rose contains more the 100 shades of red. However, Visual Components has only a few tones of red available. This could cause a distorted display. The 256 color limit is used because of the size of True Color bitmaps. 4.3.9.3 Creating Bitmaps Along with adding bitmaps, new bitmaps can also be created directly from Visual Components. If this option is chosen, an external bitmap editor (i.e. MS Paint, CorelDRAW, etc.) must be available and configured on the development system. The same limits for inserting bitmaps apply for creating bitmaps. 4.3.9.4 Editing Bitmaps 4.3.9.5 Deleting Bitmaps Creating a new bitmap: After entering the bitmap name, width, height, and color depth (monochrome or 256 colors), a blank bitmap is inserted by clicking 'OK'. The external bitmap editor specified in the Visual Components settings is also automatically started. This bitmap is visible in the editor after it is edited and saved. The external bitmap editor is started by either double−clicking on the bitmap or selecting 'Edit' from its shortcut menu. The external bitmap editor should already be configured. The bitmap must be completed using 'Save' rather than 'Save As...'. Otherwise changes are not applied in the project. Bitmaps are stored in a project as a copy of the original in the Automation Studio − Visual Components project directory. Bitmaps that are not used in the project can be deleted. Bitmaps which are used in a picture or object cannot be deleted. Bitmaps can be deleted by selecting 'Delete' from their shortcut menu or by pressing the 'Del' key. Warning: Both the bitmap entry in the manager and the bitmap file in the project directory are deleted. Introduction to Visual Components 2.3 290 4.3.9.3 Creating Bitmaps
Introduction to Visual Components 2.3 4.3.9.6 External Bitmap Editor The external bitmap editor must first be configured before it can be used. Configuration takes place under the 'Project' tab after the 'VC Settings...' entry is selected from the 'Tools' menu. This field determines the file path for the bitmap editor. The 'Browse' button can be used to select a desired file. In this example, the Windows drawing program 'MS Paint' is used. This should be available on all Windows systems. Note: The program name and path is not always the same on all Windows versions! 4.3.9.7 Transparent Bitmaps Transparent effects can be applied to bitmaps using the Visual Components editor. In other words, a specified color can be 'disabled' during runtime, i.e. shown with the background color of the display. 4.3.9.7.1 How do transparent bitmaps work? This function is explained in the following example. The icon shown here to the right is used for the example. This icon has a white background. The icon should have a blue background since it is surrounded by a blue border. After activating Transparent mode, the white color of the icon is no longer displayed. This is how the background color is displayed during runtime. 4.3.9.7.2 Creating transparent effects Transparent effects are configured in the bitmap view. 4.3.9.6 External Bitmap Editor 291
