如何填充文本框？(How do I populate my textboxes?)
我正在为我的实习制作一个网站，我遇到了一个问题。 将数据从我的数据库检索到我的文本框中。 如果可能，每个人都有自己的信息。 例如; 我有一个John的文本框，他有一个名字和电子邮件。 杰克也有一个名字和电子邮件。 两者都需要从数据库中选择并放入表单中。 这是一个可以更改人员信息的表单。 你可以在这里看到网站。 点击“Wijzig”按钮查看我的意思。

Retrieving data from my database into my textboxes. If possible, each person their own information. For example; I have a textbox for John, he has a name and email. Jack also has a name and email. Both need to be selected from the database and put in the form. It's a form where you can make changes to the persons information. You can see the website yourself here. Click on the button "Wijzig" to view the form I mean.

您必须添加
scale_color_identity才能按“原样”采用颜色：ggplot(data=image.rgb, aes(x=x, y=y, col=rgb(r,g,b))) + geom_point() + scale_color_identity()您提供的样本数据提供非常相似的颜色，因此所有点都显示为黑色。 使用
geom_tile，不同的颜色更加明显：ggplot(data=image.rgb, aes(x=x, y=y, fill=rgb(r,g,b))) + geom_tile() + scale_fill_identity()
You must add
scale_color_identityin order for colors to be taken "as is" :ggplot(data=image.rgb, aes(x=x, y=y, col=rgb(r,g,b))) + geom_point() + scale_color_identity()The sample data you provided give very similar colors, so all the points seem to be black. With
geom_tilethe different colors are a bit more visible :ggplot(data=image.rgb, aes(x=x, y=y, fill=rgb(r,g,b))) + geom_tile() + scale_fill_identity()

您可以在rasterGrob设置宽度和高度参数， rasterGrob都等于1“npc”，这将强制图像填充绘图区域。 然后在保存图像时指定图像的高度和宽度，以获得所需的高宽比。 主题和scale_y_reverse选项可用于控制轴的外观，如下所示。 请注意，我们也可以使用expand参数来确保轴不会比图像或数据更远。 g <- rasterGrob(img, width=unit(1,"npc"), height=unit(1,"npc"), interpolate = FALSE) g_ct <- gg ...
