GIMP Python-fu 导出文件只导出透明层 [英] GIMP Python-fu exporting file only exports transparent layer

问题描述

我在通过 GIMP 在 python 中保存图像时遇到问题.我可以获得图像并应用我想要的效果，但是当我去保存时，它只保存一层而不是所有内容(注意:背景是透明的)并且因为背景是透明的，所以我无法保存任何东西透明背景.我正在使用的代码发布如下:

I am having issues saving images in python via GIMP. I can get the image and apply the effects I want, but when I go to save, it only saves one layer and not everything (NOTE: The background is transparent) and because the background is transparent, I cannot get it to save anything besides the transparent background. The code I am using is posted below:

image_array = gimp.image_list()
i=0
for image in image_array:
    img = image_array[i]
    layers = img.layers
    last_layer = len(layers)-1
    try:
        disable=pdb.gimp_image_undo_disable(img)
        pdb.gimp_layer_add_alpha(layers[0])
        drw = pdb.gimp_image_active_drawable(img)
        pdb.plug_in_colortoalpha(img,drw,(0,0,0))
        drw = pdb.gimp_image_active_drawable(img)
        enable = pdb.gimp_image_undo_enable(img)

    except:
        print "ERROR"

    pdb.file_png_save(img, drw, "C:\\Users\\jammer\\Desktop\\test.png",
                      "test.png",0,9,1,1,1,1,1)
    i+=1

我也尝试过 file_png_save2，但我感觉问题出在 drw 对象上，因为我只想复制单击 File->Export 和无需通过 GUI 即可保存为 PNG.我宁愿让它自动保存(我有 49 个图像，每个图像都会自动命名，但首先我需要让它用一张图像正确导出).正如我之前所说，上面的代码只导出透明背景，即使更改为 GIF 也不能解决问题.如何在保留所有图层和透明背景的同时将文件导出为 PNG?

I have also tried file_png_save2, but I have a feeling the problem lies in the drw object as I just want to replicate the option of clicking File->Export and saving as PNG without doing that via GUI. I would rather have it save automatically (I have 49 images and each will be named automatically, but first I need to get it to export correctly with one image). as I said before, the code above only exports a transparent background, even changing to a GIF does not resolve the issue. How do I export a file as a PNG while keeping all layers and transparent background?

推荐答案

我发现了我的问题！我没有合并可见图层并将其设置为等于新图层，然后在将图像保存为 png 时将其用作可绘制对象"！我已经在下面发布了固定代码:

I found my problem! I was not merging the visible layers and setting that equal to the new layer, which I then used as the "drawable object" when saving the image as a png! I have posted the fixed code below:

image_array = gimp.image_list()
i=0
for image in image_array:
    img = image_array[i]
    layers = img.layers
    last_layer = len(layers)-1
    try:
        disable=pdb.gimp_image_undo_disable(img)
        pdb.gimp_layer_add_alpha(layers[0])
        drw = pdb.gimp_image_active_drawable(img)
        pdb.plug_in_colortoalpha(img,drw,(0,0,0))
        layer = pdb.gimp_image_merge_visible_layers(img, gimpfu.CLIP_TO_IMAGE)#FIXES PROBLEM OF ONLY EXPORTING TRANSPARENCY!
        enable = pdb.gimp_image_undo_enable(img)

    except:
        print "ERROR"

    pdb.file_png_save2(img, layer, "C:\\Users\\jammer\\Desktop\\test.png","test.png",1,9,1,1,1,1,1,0,1)
    i+=1
