根据当前填充颜色更改注释填充

Question

我正在尝试根据当前填充或描边颜色更改注释的填充和描边颜色。

例如，注解填充的当前 RGB 是：

["RGB", 170/255, 110/255, 40/255]

我也需要使用此填充更改所有注释：

["RGB", 255/255, 250/255, 180/255]

我有以下但没有进展。

    this.syncAnnotScan();
var annots = this.getAnnots();
for (var i = 0; i < annots.length; i++) {
    if (annots[i].fillColor == ["RGB", 170/255, 110/255, 40/255]) { // What is the colour we are searching for?
        annots[i].fillColor = ["RGB", 255/255, 250/255, 180/255]; // Fill Colour Change
        annots[i].strokeColor = ["RGB", 255/255, 250/255, 180/255]; // Stroke Colour Change 
    }
}

如有任何帮助，我们将不胜感激。

您需要执行 color.equal()，根据文档说明：https://www.adobe.com/content/dam/acom/en/devnet/acrobat/pdfs/js_api_reference.pdf 第 430 页

this.syncAnnotScan();
var annots = this.getAnnots();
var annotsLength = annots.length;
var colourTarget = ["RGB", 0.9019622802734375, 0.0980377197265625, 0.2941131591796875];
var colourChangeTarget = ["RGB", 255/255, 250/255, 180/255];

for (var i = 0; i < annotsLength; i++)
{
    if(color.equal(annots[i].fillColor, colourTarget))
    {
        annots[i].fillColor = colourChangeTarget;
        annots[i].strokeColor = colourChangeTarget;
    }
}
