ASP Image 使用範例

使用ASPImage組件僅需以下步驟：
建一個對象
設定若干屬性
調用SaveImage方法
以下代碼舉例說明如何在vbscript中使用ASPImage組件，在這個例子中我們要建立一個漸進填充的字樣為 "welcome to"的文字圖片：
Set Image = Server.CreateObject("AspImage.Image")
rem Set various font parameters
Image.FontColor = vbBlack
Image.Italic = True
Image.Bold = True
Image.FontName = "Arial"
Image.FontSize = 12
Image.PadSize = 10
rem Calculate how big our text info is and set the image to this size
remThis has to be done since we want to fill the area with a gradient
strMessage = "Welcome to"
Image.MaxX = Image.TextWidth (strMessage)
Image.MaxY = Image.TextHeight (strMessage)
rem Create a one way gradient
Image.GradientOneWay vbRed, vbWhite, 0
rem Print our string to the image
Image.TextOut strMessage, Image.X, Image.Y, false
rem Set the filename and save
remNOTE: You should gen the filename dynamically for multiuser usage
Image.FileName = "d:inetpubwwwrootimagesmsg1.jpg"
if Image.SaveImage then
rem The image was saved so write the <img src> tag out for the browser to pick up
Response.Write "<img src=""/images/msg1.jpg""><br>"
else
rem Something happened and we couldn't save the image so just use an HTML header
remWe need to debug the script and find out what went wrong
Response.Write "<h2>Welcome to</h2>
end if
通過使用SaveImage方法我們可以得知圖片是否已經正確儲存了。一般導致圖片不能正確儲存的原因是圖片的儲存路徑不合法或者對該路徑沒有寫的許可權。
GIF Animations
圖片能被載入或進行處理，並且可以通過調用AddImage方法將這些修改儲存到一個活動順序的動畫中。在soianim.asp中有個簡單的GIF動畫例子，這個檔案已打包到ASPImage的ZIP檔案中。
