问题描述

how to divide the image into picturebox ? changing the size in centimeters ! as in-app "ace poster"

推荐答案

Horizo​​ntalResolution和VerticalResolution属性包含该Image对象的DPI分辨率。 Wifth和Height将以像素为单位给出实际大小。计算有多少像素代表厘米很简单。此时，您可以定义等于A4纸张的矩形。您可以使用 Bitmap.Clone [ ^ ]提取图块。

只是一个注意事项：如果你想要所有这些都在瓷砖上打印，你应该关心不可打印的边距和重叠。

The HorizontalResolution and VerticalResolution properties contain the resolution in DPI of that Image object. Wifth and Height will give you the actual size in pixels. It is simple to calculate how many pixels represent a centimeter. At that point you can define the rectangle that equals to an A4 sheet. You can use Bitmap.Clone[^] to extract the tiles.
Just a note: if you want all this to print in tiles, you should care about the non-printable margins and of the overlap.
