- BgImage.DLL - NSIS extension DLL
- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
- Displays an image or a gradient with user defined texts and/or images behind the NSIS window.
- Can also play WAVs.
-
- See Example.nsi for a usage example.
-
- Usage
- ~~~~~
-
- 1) Call SetBg to set the background
- 2) Call AddText, or AddImage to add texts and images
- 3) Call Redraw to update the background window
- 4) Optional - repeat steps 2-3 to add more images
- -or-
- call Clear and repeat steps 1-3 for a completely new background.
- 5) Call Destroy when the background is no longer required (.onGUIEnd for example)
-
- Notes
- ~~~~~
-
- * All but the last used function (which should be Destroy) must use /NOUNLOAD so the image window won't be destroyed before it should.
-
- * This plugin requires NSIS 2.0b4 and above.
-
- * Do not call SetBg (which creates the window) from a section or a function called by a section.
-
- * Never use /NOUNLOAD in .onInstSuccess and .onInstFailed. Failing to do so will cause the installer to crash.
- This means you should not call Destroy from .onInstSuccess or .onInstFailed.

- Available functions
- ~~~~~~~~~~~~~~
-
- SetBg [/FILLSCREEN|/TILED] path_to_bitmap
- SetBg /GRADIENT R G B R G B
- Sets the background and creates the window if necessary
- Use /FILLSCREEN to make the image fill the screen
- Use /TILED to set a tiled background
- Use /GRADIENT to set a gradient background
-
- If SetReturn on was called returns "success" on the stack
- or an error string if there was an error
-
- Do not use in .onInit!
-
- AddImage [/TRANSPARENT R G B] path_to_bitmap X Y
- Adds an image to the background window at (X,Y)
- X and Y can be negative to specify distance from right/bottom
- Use /TRANSPARENT to make BgImage draw the image transparently
- Define the transparent color using R G B
-
- If SetReturn on was called returns "success" on the stack
- or an error string if there was an error
-
- AddText text font_handle R G B X Y X Y
- Adds text to the background window
- Use NSIS's CreateFont to create a font and pass it as font_handle
- Use R G B to set the text color
- The first X Y is for the top left corner of the text box
- The second X Y is for the bottom right corner of the text box
- X and Y can be negative to specify distance from right/bottoms
-
- If SetReturn on was called returns "success" on the stack
- or an error string if there was an error
-
- Clear

- Use /WAIT to wait for the sound to finish playing
- Use /LOOP to loop the sound
- Use Sound /STOP to stop the loop
-
- SetReturn on|off
- Enable return values from SetBg, AddImage and AddText
- Default value is off because all of the possible errors
- are either things you should handle when debugging your script
- such as "can't load bitmap" or errors you can do nothing about
- such as "memory allocation error"
