当表单保存为tiff格式时如何设置纸张大小。 [英] how to set a paper size when form is save as tiff format.

问题描述

我已将vb格式保存为Tiff图像格式。

现在我想在保存表格作为tiff时设置A4纸张尺寸。

我该怎么办？它？

解决方案

术语A4定义图像的大小（以毫米为单位），但图像只有像素大小。它的长度单位没有一定的大小，因为它取决于图像的显示方式。某些图像格式也具有分辨率信息（每英寸或每毫米的行数），但实际上这是一个虚假参数，某些程序可以使用它来定义重新采样图像的某些因素（如果需要）。



以下是更改分辨率的方法： http://msdn.microsoft.com/en-us/library/system.drawing.bitmap.setresolution.aspx [ ^ ]。



您应该意识到，您经常会面临滥用解决方案一词的行为。人们错误地称之为分辨率，实际上是像素的大小。这是完全不同的东西。分辨率是某些系统将两条线识别为单独的能力，并以每英寸线数（mm）表示。在您的情况下，A4仅指示图像的宽高比。您可以在此处找到纸张尺寸，并根据以下信息推断纵横比：

实际大小（以像素为单位）取决于您的选择。

I have save vb form as a Tiff image format.
Now i want set a paper size A4 when save a form as a tiff.
How can i do it??

解决方案

The term A4 defines the sizes of an image in millimeters, but the image has only the size in pixels. It does not have a certain size in length units, because it depends on how the image is displayed. Some image formats also have the "resolution" information (lines per inch or per millimeter), but practically this is a bogus parameter, it can be used by some programs to define certain factor in resampling the image (if required).

Here is how you can change the resolution: http://msdn.microsoft.com/en-us/library/system.drawing.bitmap.setresolution.aspx[^].

You should be aware that you can often face a misuse of the term "resolution". People mistakenly call "resolution" which is actually a size of something in pixels. This is something completely different. Resolution is the ability of some system to recognize two lines as separate and is expressed in lines per inch (mm). In your case, A4 only dictates you the aspect ratio of the image. You can find the paper size here and infer the aspect ratio from this information:

The actual size in pixels depends on your choice.
