Where is Image.GrabImage ?

[gcmartijnParticipant]

I’m busy with translating code but now i’m searching for this monkey1 function

http://www.monkey-x.com/docs/html/Modules_mojo.graphics_Image.html#GrabImage

Monkey

Image = atlas_sprite.GrabImage( frame["x"].ToInt(), frame["y"].ToInt(), frame["w"].ToInt(), frame["h"].ToInt(), 1, Image.Handle)

1 2 3 4 5 6 7 8

Image = atlas_sprite.GrabImage( frame["x"].ToInt(), frame["y"].ToInt(), frame["w"].ToInt(), frame["h"].ToInt(), 1, Image.Handle)

My game uses many sprites (and animations) using atlas files.
But I can’t find this function for MX2

You can grab a sub-section of an image with new image(image, recti) plus there’s a few other overloaded options I think. Here’s my function to load an animation from a spritesheet, it might have what you’re looking for?

Monkey

Function LoadFrames:Image[] (path:String, numFrames:Int, cellWidth:Int, cellHeight:Int, padded:Bool = False, flags:TextureFlags = TextureFlags.Filter, shader:Shader = Null) Local material:=Image.Load( path, flags, shader ) If Not material Return New Image[0] If cellWidth * cellHeight * numFrames > material.Width * material.Height Return New Image[0] Local frames:= New Image[numFrames] If cellHeight = material.Height Local x:=0 local width:=cellWidth If padded x += 1 width -= 2 End if For Local i:=0 Until numFrames local rect:= New Recti(i * cellWidth + x, 0, i * cellWidth + x + width, cellHeight) frames[i] = New Image(material, rect) Next Else Local x:= 0, width:= cellWidth, y:= 0, height:= cellHeight Local columns:= material.Width / width If padded x += 1 y += 1 width -= 2 height -= 2 End If For Local i:=0 Until numFrames Local fx:Int = i Mod columns * cellWidth Local fy:Int = i / columns * cellHeight local rect:= New Recti(fx + x, fy + y, fx + x + width, fy + y + height) frames[i] = New Image(material, rect) Next End If Return frames End

Thanks for sharing, I found the image overload in the modules section now.

I’m wondering if there are some Atlas restrictions like grapimage have.

These are.
Multiple frame images are assumed to be laid out in a horizontal strip, in which case width and height are the dimensions of each frame, and the source image must be wide enough to contain the entire strip.
Note that if image flags includes any padding, then the specified rectangle includes padding. This means image width and/or height may be ‘2 less’ than the width and/or height you specify.

For New Image(img,recti(x,y,x2,y2))

Because I get some weird things using a new spritesheet Atlas creator.

I guess that all sort of Atlas image formats are now allowed , and no 1px padding is needed anymore ?

Usefull information for others.
