_gtkPixNew¶

create a new pix object

Prototype : fun [Chn P I [I I I]] ObjGtkPix

channel	Chn	a channel
filename	P	an image filename
mode	I	Mode. Should be at 0.
tuple	[I I I]	the width (or nil to not constraint it),
		the height (or nil to not constraint it),
		the ratio (1 to keep it)

Return : ObjGtkPix : a new pix object or nil if an error occurs

_gtkPixFree¶

Destroys a pix object

Prototype : fun [ObjGtkPix] I

Return : I : always 0 except if error, it returns nil

_gtkPixScale¶

Scale

Prototype : fun [ObjGtkPix I I I I] ObjGtkPix

pix	ObjGtkPix	a valid pix object
width	I	the new width
height	I	the new height
mode	I	an algorithm at your choice :	SCOL_GTK_PIX_INTERP_BILINEAR (default) :
			SCOL_GTK_PIX_INTERP_NEAREST :
			SCOL_GTK_PIX_INTERP_TILES :
			SCOL_GTK_PIX_INTERP_HYPER :
flag	I	if 1, the pix in the pix object pix will be destroyed.	If 0, the pix object pix will be kept and a new pix object will be created.

Return : ObjGtkPix : a new pix object or nil if an error occurs.

_gtkPixScaleEx¶

Not implemented yet.

Return : always nil.

_gtkPixRotate¶

Performs a rotation

Prototype : fun [ObjGtkPix I I] ObjGtkPix

pix	ObjGtkPix	a pix object
angle	I	0, 90, 180 or 270 degrees. Others values are ignored
flag	I	0 if the new pix Scol object is created with the rotated pix
		1 if the new pix replaces the pix in the curent pix object pix

Return : ObjGtkPix : a rotated pix in the (new or same) pix object or the same pix object if the value is bad or nil if an error occurs

Return Api
