Title: Struggle with rendering soft-&hardwareimages simultaneous
Post by: MrFreyer on November 01, 2019, 03:35:46 am
Hi,

I have some problems with displaying soft- and hardwareimages simultaneously on the screen.

The following program should print some text, wait for a keyinput and then draw a grey box and also print some text while waiting for another keyinput...

Code: QB64: [Select]
  1. DEFINT A-Z
  2.  
  3. desktopscreen.width = _DESKTOPWIDTH
  4. desktopscreen.height = _DESKTOPHEIGHT
  5.  
  6. screenwindow.width = 1280
  7. screenwindow.height = 720
  8.  
  9.  
  10. SCREEN _NEWIMAGE(screenwindow.width, screenwindow.height, 32)
  12. _SCREENMOVE (desktopscreen.width * 0.5 - screenwindow.width * 0.5), 0
  15.  
  16.  
  17. 'SW = softwareimage / HW = hardwareimage
  18. DIM drawlayerSW AS LONG
  19. DIM drawlayerHW AS LONG
  20.  
  21. DIM boxpictureSW AS LONG
  22. DIM boxpictureHW AS LONG
  23.  
  24.  
  25. drawlayerSW = _NEWIMAGE(screenwindow.width, screenwindow.height, 32)
  26. drawlayerHW = _COPYIMAGE(drawlayerSW, 33)
  27.  
  28.  
  29. 'create boxpicture
  30. boxpictureSW = _NEWIMAGE(64, 64, 32)
  31. _DEST boxpictureSW
  32. LINE (0, 0)-(63, 63), _RGB(70, 70, 70), BF
  34. boxpictureHW = _COPYIMAGE(boxpictureSW, 33)
  35.  
  36.  
  37. 'draw boxpicture on drawlayer
  38. _PUTIMAGE (120, 120), boxpictureHW, drawlayerHW
  39.        
  40.        
  41. 'print text and wait for keyinput
  43. COLOR _RGB(255, 255, 255), _RGB(0, 0, 0)
  44. _PRINTSTRING (0, 0), "TESTTEXT 1 - Press any key"
  47.  
  48.    
  49. 'draw drawlayer and print text, wait for keyinput
  51.     CLS
  52.  
  53.     _PUTIMAGE (0, 0), drawlayerHW
  54.  
  55.     COLOR _RGB(255, 255, 255), _RGB(0, 0, 0)
  56.     _PRINTSTRING (0, 0), "TESTTEXT 2 - Press any key"
  57.      
  58.     _DISPLAY
  59.  
  61.  
  63.  

What I get: print NO text and wait for keyinput, draw box and print text while waiting for keyinput, print text AGAIN while waiting for ANOTHER keyinput :D I do something wrong with the destinationimages or displayorder, I think...

Thanks

Hi MrFreyer!
Your program is running fine on my system. I have found no issue in running it on my laptop.
Which version of QB64 are you using??

I'm using version 1.3 win x64...

You get the screen with "TESTTEXT 1 - Press any key"?
I just get a black screen :/

I can confirm Ashish results, I get text also before a keypress...

My toolbar is on left side so _SCREENMOVE is off for me but..
