h2. _gtkPixNew
create a new pix object
Prototype : *fun [Chn P I [I I I]] ObjGtkPix*
table.
|*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
h2. _gtkPixFree
Destroys a pix object
Prototype : *fun [ObjGtkPix] I*
+Return+ : I : always 0 except if error, it returns nil
h2. _gtkPixScale
Scale
Prototype : *fun [ObjGtkPix I I I I] ObjGtkPix*
table.
|*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.
h2. _gtkPixScaleEx
Not implemented yet.
+Return+ : always nil.
h2. _gtkPixRotate
Performs a rotation
Prototype : *fun [ObjGtkPix I I] ObjGtkPix*
table.
|*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
h2. _gtkPixFlip
Performs a flip to a pix object
Prototype : *fun [ObjGtkPix I I] ObjGtkPix*
table.
|*pix*|ObjGtkPix|a pix object|
|*flip*|I|SCOL_GTK_PIX_FLIP_HORIZONTAL or SCOL_GTK_PIX_FLIP_VERTICAL. Other value are ignored.|
|*flag*|I|0 if the new pix Scol object is created with the flipped pix|
| | |1 if the new pix replaces the pix in the curent pix object _pix_|
+Return+ : ObjGtkPix : a flipped 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]]
