MultiPut V2.0 :-)

[leopardpm]

for the rotation, will you use the full 0 to 360 degrees, or just steps like 0,45,90,135,180,225,etc....?

[leopardpm]

Trying to just save memory. ... I have a MINUMUM of 53 images, 52 'cards' and at least one 'back'. Maybe the two Jokers.
About the only thing that I could think of at the moment would be create another temp image, Put the 'ShowThis' in it using the PReset.
Then use Multiput to rotate and put it on screen.

that ain't alot of memory usage at all.. I would say to definitely do it with a second ShowThis...

Code: Select all

'Rot value (Rotate) not used at the moment
Sub Card.DrawImg(ByVal XLoc As Integer, ByVal YLoc As Integer, GetCard As Integer, Selected As Integer, Rot As Single=0)
	Dim As Any Ptr ShowThis(1)
	ShowThis(0)  = 0
	'
	Select Case GetCard
		Case -1
			ShowThis(0) = Backs(CurBackGr)
		Case 0 To 51
			ShowThis(0) = Deck52(GetCard)
		Case 52
			If Jokers Then ShowThis(0) = JokerBlack
		Case 53
			If Jokers Then ShowThis(0) = JokerRed
		Case Else
			'54+
			'special image
			'As Integer Special
			'As Any Ptr SpecialRC(Any)
			If Special > GetCard - 54 Then ShowThis(0) = SpecialRC(GetCard - 54)
	End Select
	'If Rot > 0 Then
	'	'insert rotation code or call a sub/function
	'EndIf
	......put ShowThis(0) into ShowThis(1) using PRESET here
	if ShowThis(0) then MultiPut ,xloc,yloc,ShowThis(Selected),1,1,rotation,transparent
End Sub

Is there a way via the parameters sent to change the point of rotation?
As I see it, it is like putting a "pin" in the center of a picture and to be able to spin it.
I would like the "pin" to be somewhere else, for my use, in the upper left corner.

@bcohio2001:
I have always tried to discover the secret of Multiput, there I have never succeeded ... :(
So the following snippet is more a homage to dj... great work!
but it contains exactly the feature you are looking for:

Here is a tip... translate, rotate, translate back. :)

[bcohio2001]

@Mutton
Thanks.
And FYI received error:
RotPut.bas(14) error 14: Expected identifier, found 'Image' in 'dim as Image ptr Src_Header,Dest_Header 'Zeiger um an die Daten im ImageHeader zu kommen'
Assuming that you included 'fbgfx.bi' somewhere else in a larger project.
Will just use ImageInfo in my copy.

*Edit*
I guess I ASSuMEd wrong, notice the emphasis on 'me'.
Is not in 'fbgfx.bi'!
Much more to it than just getting ImageInfo and like you is beyond me.

[Dr_D]

Alas, Rotozoom has the capability as well, but it has fallen by the wayside. :p

[bcohio2001]

@D.J. Peters

Please specify in either the code or in the first post text that rotating an image with an odd width or height can result in loss of an edge of the image.
All your tests are with images with even dimensions.

Personally I think MultiPut should be added to the GFX library. Along with some collision detection routine, perhaps, too

Hi all, old coder, new user here.

I am trying to use MultiPut V2 and am having slightly more success with it than with the first few iterations. It looks like a great tool but I still can't seem to get it to work properly.

When I display my 8x8 sprite on screen using multiput, if the rotation is 0 or 90 degrees the sprite is stretched, if it is at 270 degrees it is moved over to the right by 1 pixel (seemingly), at 180 degrees it looks fine (but upside down though obvs). Should it still work? I am on the latest version of FB, Win10 64bit.

Is there a version of FB that is ideal for using MultiPut and if so will it run in the 64bit version of that release? I have tried a few versions of FB along with most of the iterations of MultiPut that I came across. I could never get MultiPut to even show anything until I found V2, the version with the yellow smiley didn't work and also the version with the white square grid. Nothing would happen.

Thanks in advance for any help.

EDIT: I just tested it by scaling it up to 2 instead of 1. It now shows better but there is a line of pixels missing from the bottom of the sprite at 0 degrees, at 90 it seems stretched or there is an extra row of pixels added at the top and one missing at the bottom again. At 180 and 270 degrees everything looks perfect.

This is my code...

Code: Select all

' FB 1.07.3 Win64
#include "multiput.bi"

screen 18,32
Dim spr_pedehead As Any Ptr  = ImageCreate(8,8)
bload"img\pedehead1.bmp",spr_pedehead

Do       

    MultiPut ,100,100,spr_pedehead,1,1,0,1
    put (120,120),spr_pedehead,trans
    screensync

Loop Until inkey <>""

ImageDestroy spr_pedehead

The second 'put' is there just to draw the sprite as it is meant to look, for comparison

Hi all, old coder, new user here.

I am trying to use MultiPut V2 and am having slightly more success with it than with the first few iterations. It looks like a great tool but I still can't seem to get it to work properly.

When I display my 8x8 sprite on screen using multiput, if the rotation is 0 or 90 degrees the sprite is stretched, if it is at 270 degrees it is moved over to the right by 1 pixel (seemingly), at 180 degrees it looks fine (but upside down though obvs). Should it still work? I am on the latest version of FB, Win10 64bit.

Is there a version of FB that is ideal for using MultiPut and if so will it run in the 64bit version of that release? I have tried a few versions of FB along with most of the iterations of MultiPut that I came across. I could never get MultiPut to even show anything until I found V2, the version with the yellow smiley didn't work and also the version with the white square grid. Nothing would happen.

Thanks in advance for any help.

EDIT: I just tested it by scaling it up to 2 instead of 1. It now shows better but there is a line of pixels missing from the bottom of the sprite at 0 degrees, at 90 it seems stretched or there is an extra row of pixels added at the top and one missing at the bottom again. At 180 and 270 degrees everything looks perfect.

Hi, Dan. Welcome! Maybe this is what's wrong?

@D.J. Peters

Please specify in either the code or in the first post text that rotating an image with an odd width or height can result in loss of an edge of the image.
All your tests are with images with even dimensions.

Hi, thanks for the reply :)

I am not sure what you mean by this "Please specify in either the code or in the first post text that rotating an image with an odd width or height can result in loss of an edge of the image. All your tests are with images with even dimensions."

My image has an even amount of pixels, it is 8x8. Also, I don't have to change the rotation for it to 'fail', it does it at 0 rotation / 0 degrees.
