pdb.gimp_paintbrush_default似乎非常慢(几秒钟,使用标准画笔为500点。线条更糟,显然)。这是这样的吗?使用用户选择的画笔绘制直线时,有没有办法加快速度?
pythonfu控制台代码:
from random import randint
img=gimp.image_list()[0]
drw = pdb.gimp_image_active_drawable(img)
width = pdb.gimp_image_width(img)
height = pdb.gimp_image_height(img)
point_number = 500
while (point_number > 0):
x = randint(0, width)
y = randint(0, height)
pdb.gimp_paintbrush_default(drw,2,[x,y])
point_number -= 1
答案 0 :(得分:2)
我一直在做一些非常相似的事情并且也遇到了这个问题。这是我发现的一种技术,它使我的功能快了大约5倍:
我相信这会加速,因为GIMP不必将编辑内容绘制到屏幕上,但我并不是100%肯定。这是我的职责:
def splotches(img, layer, size, variability, quantity):
gimp.context_push()
img.undo_group_start()
width = layer.width
height = layer.height
temp_img = pdb.gimp_image_new(width, height, img.base_type)
temp_img.disable_undo()
temp_layer = pdb.gimp_layer_new_from_drawable(layer, temp_img)
temp_img.insert_layer(temp_layer)
brush = pdb.gimp_brush_new("Splotch")
pdb.gimp_brush_set_hardness(brush, 1.0)
pdb.gimp_brush_set_shape(brush, BRUSH_GENERATED_CIRCLE)
pdb.gimp_brush_set_spacing(brush, 1000)
pdb.gimp_context_set_brush(brush)
for i in range(quantity):
random_size = size + random.randrange(variability)
x = random.randrange(width)
y = random.randrange(height)
pdb.gimp_context_set_brush_size(random_size)
pdb.gimp_paintbrush(temp_layer, 0.0, 2, [x, y, x, y], PAINT_CONSTANT, 0.0)
gimp.progress_update(float(i) / float(quantity))
temp_layer.flush()
temp_layer.merge_shadow(True)
# Delete the original layer and copy the new layer in its place
new_layer = pdb.gimp_layer_new_from_drawable(temp_layer, img)
name = layer.name
img.remove_layer(layer)
pdb.gimp_item_set_name(new_layer, name)
img.insert_layer(new_layer)
gimp.delete(temp_img)
img.undo_group_end()
gimp.context_pop()
