好的,我正在尝试开发一个小插件为gimp,使一个位图字体。由于某种原因,我添加了下面的代码,它将无法工作。
current_cell_x = 0
current_cell_y = 0
x_pos = current_cell_x * cwidth
y_pos = current_cell_y * cheight
x_pos += cwidth / 2.0
y_pos += cheight / 2.0
x_pos -= text_layer.width / 2.0
y_pos -= text_layer.height / 2.0即使是“current_cell_x=0”的第一行也足以使整个插件无法工作。
以下是工作格式的所有代码:
from gimpfu import *
def create_font(cwidth, cheight, xcells, ycells, font, size, color) :
char_begin = 32
char_end = 127
num_chars = char_end - char_begin
#current_cell_x = 0
#current_cell_y = 0
# Figure out total width & height
twidth = int(cwidth * xcells)
theight = int(cheight * ycells)
# Create Image
img = gimp.Image(twidth, theight, RGB)
img.disable_undo()
# Save the current foreground color:
pdb.gimp_context_push()
# Set the text color & background color
gimp.set_foreground(color)
gimp.set_background(0, 0, 0)
# Create All Layers & Position Accordingly
for i in range(char_begin, char_end):
string = '%c' % i
offset = i - char_begin
text_layer = pdb.gimp_text_fontname(img, None, 0, 0, string, -1, True, size, PIXELS, font)
#x_pos = current_cell_x * cwidth
#y_pos = current_cell_y * cheight
#x_pos += cwidth / 2.0
#y_pos += cheight / 2.0
#x_pos -= text_layer.width / 2.0
#y_pos -= text_layer.height / 2.0
#pdb.gimp_image_flatten(img)
img.enable_undo()
# Create a new image window
gimp.Display(img)
# Show the new image window
gimp.displays_flush()
# Restore the old foreground color:
pdb.gimp_context_pop()
register(
"python_fu_bitmap_font",
"Bitmap Font",
"Create a new bitmap font",
"*****",
"*****",
"2013",
"Bitmap Font (Py)...",
"", # Create a new image, don't work on an existing one
[
(PF_SPINNER, "cwidth", "Cell Width", 24, (1, 3000, 1)),
(PF_SPINNER, "cheight", "Cell Height", 51, (1, 3000, 1)),
(PF_SPINNER, "xcells", "Cells on X axis", 10, (1, 3000, 1)),
(PF_SPINNER, "ycells", "Cells on Y axis", 10, (1, 3000, 1)),
(PF_FONT, "font", "Font face", "Consolas"),
(PF_SPINNER, "size", "Font size", 50, (1, 3000, 1)),
(PF_COLOR, "color", "Text color", (1.0, 0.0, 0.0))
],
[],
create_font, menu="<Image>/File/Create")
main()但是,当我不注释第9-10行和第33-40行时,我会得到以下错误。



我希望我的最后代码看起来像这样:
def create_font(cwidth, cheight, xcells, ycells, font, size, color) :
char_begin = 32
char_end = 127
num_chars = char_end - char_begin
current_cell_x = 0
current_cell_y = 0
# Figure out total width & height
twidth = int(cwidth * xcells)
theight = int(cheight * ycells)
# Create Image
img = gimp.Image(twidth, theight, RGB)
img.disable_undo()
# Save the current foreground color:
pdb.gimp_context_push()
# Set the text color & background color
gimp.set_foreground(color)
gimp.set_background(0, 0, 0)
# Create All Layers & Position Accordingly
for i in range(char_begin, char_end):
string = '%c' % i
text_layer = pdb.gimp_text_fontname(img, None, 0, 0, string, -1, True, size, PIXELS, font)
pdb.plug_in_autocrop_layer(0, img, text_layer)
x_pos = float(current_cell_x * cwidth)
y_pos = float(current_cell_y * cheight)
x_pos += float(cwidth) / 2.0
y_pos += float(cheight) / 2.0
x_pos -= float(text_layer.width) / 2.0
y_pos -= float(text_layer.height) / 2.0
text_layer.translate(x_pos, y_pos)
#Set current cell
current_cell_x += 1
if current_cell_x > xcells:
current_cell_x = 0
current_cell_y += 1
if current_cell_y > ycells:
break
gimp.progress_update(float(offset) / float(num_chars))
#pdb.gimp_image_flatten(img) # Don't do this
img.enable_undo()
# Create a new image window
gimp.Display(img)
# Show the new image window
gimp.displays_flush()
# Restore the old foreground color:
pdb.gimp_context_pop()如果你认为有什么建议的话,我不介意。
注意:我的代码来自- font.py和http://gimpbook.com/scripting/
Ran 'python -tt plugin.py‘并得到以下内容:

我有不一致的缩进,我需要转到Settings>Preferences>Language菜单/标签Settings>Tab设置,然后检查替换空间。
然后我要跑
python -tt yourscript.py这让我摆脱了我的教诲所造成的所有印字错误。
我还使用了Python33 33/Tools/Script文件夹中的reindent.py,但它对我不起作用。这可能在某种程度上有所帮助,我没有看到。
马提亚斯说对了一半,但他没有给出答案。我在他的位置上这样做。

CMD窗口上的错误是:在源代码中混合制表符和空格--确保添加到代码中的行仅以空格为前缀,而不是以制表符(\x09)字符作为前缀。
您应该配置用于编辑Python代码的编辑器程序,而不是使用选项卡字符。
(可能是相反,您正在编辑带有选项卡的文件,并且您的编辑器被正确配置为使用空格--在这种情况下,您应该替换所有选项卡)
