使用ASPImage組件僅需以下步驟:
建一個對象 設(shè)置若干屬性 調(diào)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(jìn)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 rem This 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 rem NOTE: You should gen the filename dynamically for multiuser usage Image.FileName = "d:\inetpub\wwwroot\images\msg1.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=""http://www.okasp.com/images/msg1.jpg""><br>" else rem Something happened and we couldn't save the image so just use an HTML header rem We 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(jīng)正確保存了。一般導(dǎo)致圖片不能正確保存的原因是圖片的保存路徑不合法或者對該路徑?jīng)]有寫的權(quán)限。
GIF Animations 圖片能被加載或進(jìn)行處理,并且可以通過調(diào)用AddImage方法將這些修改保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,這個文件已打包到ASPImage的ZIP文件中。(出處:熱點網(wǎng)絡(luò))
