Get , Put - CSslymer - 01-28-2023
Can someone help me?
How to make. I will draw several different pictures in QB64.
I want to save these pictures to the computer's memory. Then I want to develop these images using _MapTriangle.
For example: Picture(1-100)
I don't want to record them from a file..
Const Xpix = 1920
Const Ypix = 1080
Screen _NewImage(Xpix, Ypix, 32)
_FullScreen
Dim As Long Pismeno(5)
Pismo& = _LoadFont("SANFW.ttf", 300, "monospace")
_Font Pismo&
Cx = 450: CY = 110
x = 100: y = 100
For t = 1 To 5
Pismeno(t) = _NewImage(x * 2, y * 2, 32)
_Dest Pismeno(t)
Locate 1, 1: Print t
Line (Cx - x, CY - y)-(Cx + x, CY + y), , B
'Get (Cx - x, CY - y)-(Cx + x, CY + y), Pismeno(t) - I keep getting this error
Cls
Next t
For t = 1 To 5
_Source Pismeno(t)
_Dest 0
_PutImage (Cx - x + c, CY - y), Pismeno(t)
c = c + 200
Next t
_Display

Well this sorta like what I think you want. Use _PutImage for both Get and Put
Think of _PutImage as copying an Image from one container to another. The screen is one kind of Container, another is made with _NewImage and another is a handle made from LoadImage. Maybe I should say, think of _PutImage as copying from one container handle to another. Main display screen has a handle = 0.
Code: (Select All)
Const Xpix = 1290 ' you guys with the giant screen give me a break
Const Ypix = 700
Screen _NewImage(Xpix, Ypix, 32)
_FullScreen
Dim As Long Pismeno(5)
Pismo& = _LoadFont("Arial.ttf", 100, "monospace") ' don't have that other font 300 = 300 pixel high font
_Font Pismo&
Cx = 450: CY = 110
x = 100: y = 100
'For t = 1 To 5 ' one image first baby steps
Pismeno(1) = _NewImage(_PrintWidth("Hello World"), 100, 32)
Locate 1, 1: Print "Hello World"
Line (0, 0)-(_PrintWidth("Hello World"), 100), , B
'Get (Cx - x, CY - y)-(Cx + x, CY + y), Pismeno(t) - I keep getting this error
_PutImage , 0, Pismeno(1), (0, 0)-(_PrintWidth("Hello World"), 100)
Sleep 'check her out
Cls
'Next t
For t = 1 To 7
'_Source Pismeno(t)
'_Dest 0
_PutImage ((_Width - _PrintWidth("Hello World")) / 2, (t - 1) * 100), Pismeno(1), 0
'c = c + 200
Next t
_Display
SleepDon't forget to hit a key after you see first image of Print on Screen, that is image we are going to Get.
After key press we PUT the Image 7 times down middle of screen.
This is key:
_PrintWidth("Hello World")) ' tells me exactly how wide the box will be to fit the text, then we make _Newimage that size
Study _Putimage you can get and put both with it. Oh check out Keyword for day on _PUTIMAGE ;-)) I hear it's excellent LOL!

Saving images to file is a completely different thing and I recomment SMcNeill's SaveImage routines/library.

Ako urobiť. Nakreslím niekoľko rôznych obrázkov v QB64.
Tieto obrázky chcem uložiť do pamäte počítača. Potom chcem tieto obrázky vyvolať pomocou _MapTriangle.
Napríklad: Obrázok(1-100)
Nechcem ich nahrávať zo súboru.
