问题
I am developing a webapp which is suppose to generate a PDF file that contains 10 pictures. Unfortunately, there are problems with the picture size. Despite having all 10 pictures with the same resolution, the image size turns out differently in the PDF. I have programmatically sized the picture via this method for all 10 pictures
image(number).ScaleToFit(size, size);
And here is the 2 screenshots of the PDF file generated. I somehow managed to align the all of C-IMG(s) in both screenshot.
However as for the P-IMG(s), the first screenshot is working fine. However if i were to add more text into the 2nd page, the picture would not be align properly
How do I ensure those picture are aligned properly? Here is my entire code. I have been trying to solve this for half a day :(
