Question

我试图写一个脚本, 将一个层切成小和平。它运行正确, 但没有什么被粘贴到一个新的层。

def explode_layer( i, l, dx, dy ):
    T=[]
    for ix,ox in enumerate(range(l.offsets[0], l.offsets[0]+l.width, dx )):
        for iy,oy in enumerate(range(l.offsets[1], l.offsets[1]+l.height, dy)):
            pdb.gimp_rect_select(i, ox, oy, dx, dy, 2, False, 0)
            if not pdb.gimp_edit_copy(l):
                continue
            layer = pdb.gimp_layer_new(i, dx, dy, 1, 
                                       l.name+" %d,%d"%(ix,iy), 100, 0)
            i.add_layer(layer)
            floating_sel = pdb.gimp_edit_paste(layer, True)
            pdb.gimp_layer_set_offsets(floating_sel, *layer.offsets)
            pdb.gimp_floating_sel_anchor(floating_sel)
            T.append(layer)
    return T

I use gimp 2.6.8 on Ubuntu 10.04. How can I fix it? Is there a better approach?

Answer 1

I am taking a look at your script now - it is a good approach -and I found out what is wrong: when you call gimp_edit_paste, the selection you created (with gimp_rect_select) is still active, and the contents of your floated layer are clipped by it. (Actually I think they are clipepd just at the "selection_anchor" call, but that is irrelevant).

因此,在 < code> floating_sel = pdb.gimp_edit_paste( layer, True) 修正您的功能之前,添加 pdb. dedit_edit_paste( True) 线 :

def explode_layer( i, l, dx, dy ):
    T=[]
    for ix,ox in enumerate(range(l.offsets[0], l.offsets[0]+l.width, dx )):
        for iy,oy in enumerate(range(l.offsets[1], l.offsets[1]+l.height, dy)):
            pdb.gimp_rect_select(i, ox, oy, dx, dy, 2, False, 0)
            if not pdb.gimp_edit_copy(l):
                continue
            layer = pdb.gimp_layer_new(i, dx, dy, 1, 
                                       l.name+" %d,%d"%(ix,iy), 100, 0)
            i.add_layer(layer)
            pdb.gimp_selection_none(i)
            floating_sel = pdb.gimp_edit_paste(layer, True)
            pdb.gimp_layer_set_offsets(floating_sel, *layer.offsets)
            pdb.gimp_floating_sel_anchor(floating_sel)
            T.append(layer)
    return T

简单的方法是,不是明确地创建一个新的层(btw, 虽然在图像对象上有一个没有证明的“ 新层” 方法, 以创建和添加新层, 并且对大多数参数有正常默认值 - 所以, i. new_layer( & lt; name>, & lt; width>, & lt; h88>) 将足够) - 但是您可以简单地复制、粘贴, 并且它们调用 < code> new_ lay = pdb. gim_ floating_ sel_ to_ layer( & lt; floating_ sel>) 。
