Question

我正在开发一个webapp，假设生成一个包含10张图片的PDF文件。不幸的是，图片尺寸存在问题。尽管所有10张照片具有相同的分辨率，但PDF中的图像尺寸也不同。我已通过此方法以编程方式为所有10张图片调整图片大小

image(number).ScaleToFit(size, size);

以下是生成的PDF文件的2个屏幕截图。我以某种方式设法在两个屏幕截图中对齐所有C-IMG。

enter image description here

然而，对于P-IMG，第一个截图工作正常。但是，如果我要在第二页中添加更多文本，则图片将无法正确对齐

如何确保这些图片正确对齐？这是我的整个代码。我一直试图解决这个问题半天:(
