Gimp Python 脚本单独工作,但组合时不工作
Gimp Python scripts work separately but not when combined
我有一个多层 Gimp XCF 模板,我的目标是自动将 JPG 插入其中并从命令行导出它们。
我有第一个工作的 python-fu 插件用于插入图像,第二个工作的 python-fu 插件用于 flattening/saving 图像(一行执行代码) ,但我想结合这两个插件,使它们更容易从命令行调用。最后我还想自动打开 XCF 文件。现在虽然我只是想结合这两个功能。两个插件都接收“图像”和“图层”作为输入参数。
我的组合插件的函数参数是图像、图层、要插入的 JPG(文件)、用于将图像放置在 XCF 模板中的 X 和 Y 偏移量(x_offset、y_offset) ,以及导出位置 (outputFolder)。
当我将保存命令(pdb.file_jpeg_save 显示在我的代码底部附近)添加到第一个工作脚本时,它失败了。为什么它自己可以工作但在这里失败了?
我的代码如下所示。
#!/usr/bin/env python
from gimpfu import *
def add_flatten_save(image, layer, file, x_offset, y_offset, outputFolder):
''' Add image to new layer, flatten, then saveSave the current layer into a PNG file, a JPEG file and a BMP file. '''
# Indicates that the process has started.
gimp.progress_init("Opening '" + file + "'...")
try:
# Open file.
fileImage = None
if(file.lower().endswith(('.jpeg', '.jpg'))):
fileImage = pdb.file_jpeg_load(file, file)
# Create new layer.
newLayer = gimp.Layer(image, "New Layer Name", layer.width, layer.height, layer.type, layer.opacity, layer.mode)
# the +1 adds it behind the top layer
image.add_layer(newLayer, +1)
# Put image into the new layer.
fileLayer = fileImage.layers[0]
pdb.gimp_edit_copy(fileLayer)
floating = pdb.gimp_edit_paste(newLayer, True)
# Update the new layer.
newLayer.flush()
newLayer.merge_shadow(True)
newLayer.update(0, 0, newLayer.width, newLayer.height)
# Flatten + offset floating layer, then flatten image
pdb.gimp_floating_sel_to_layer(floating)
pdb.gimp_layer_set_offsets(floating, x_offset, y_offset)
pdb.gimp_image_flatten(image)
# Export JPG of flattened image
pdb.file_jpeg_save(image, layer, outputFolder + "/" + layer.name + ".jpg", "raw_filename", 0.9, 0, 0, 0, "Creating with GIMP", 0, 0, 0, 0)
else:
gimp.message("The image could not be opened since it is not an image file.")
except Exception as err:
gimp.message("Unexpected error: " + str(err))

根本问题是,当您将图像展平时,图层“layer”不再存在。
尝试在保存之前添加 layer = pdb.gimp_image_get_active_layer(image)。
