我正在开发一个 webapp，它假设生成一个包含 10 张图片的 PDF 文件。不幸的是，图片大小存在问题。尽管所有 10 张图片都具有相同的分辨率，但 PDF 中的图像大小却有所不同。我已经通过这种方法为所有 10 张图片以编程方式调整了图片大小
image(number).ScaleToFit(size, size);
这是生成的 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。
然而，对于 P-IMG(s)，第一个屏幕截图工作正常。但是，如果我要在第二页中添加更多文字，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:(
