I'm reading a folder to assess the width x height of jpeg's, to classify them in various ways. Opening each as a bitmap and reading the bitmap width and height works but of course is laborious and very slow .... I've read various JPEG file format papers but retrieving the image pixel width and height seems none too obvious. Is there a logical way in VB to get this info quickly? My jpeg's are bog-standard ones made using VB's "Bmap.Save(Fname, ImageFormat.Jpeg)".

View 7 RepliesI have a routine that creates a report which includes text and graphics. When I print to a PDF or printer the output looks great. When I draw the report on an image to save as a PNG, GIF, JPEG, etc. it does not look as good and I understand that is related to the 96 dpi native resolution. However, I made some modifications, and even though the graphics part of the image looks better, the text does not look as good as the PDF. I am creating the image using 300 dpi and text rendering is set at the highest quality.

So i am converting a metafile (EMF to be exact) to a jpeg or gif (doesn't matter as long as it's compatible with browsers) and when I do the conversion, all of the transparent pixels turn black. I have no idea how to do this in GDI+ but here is the method I am using to save the file:
Dim Img As System.Drawing.Imaging.Metafile = New System.Drawing.Imaging.Metafile(stream)
Img.Save(Server.MapPath("/FileName.gif"), System.Drawing.Imaging.ImageFormat.Gif)

If api is necessary, with that hwnd thing, how do I call it? And if you are so kind, is there a way to search for thing only for visual basic .net 2010? Because i dont find a way to practice a strict filter, and visual basic 6, or old visual basic stuff (if not other languages) appear mixed with the program i use.
View 1 RepliesThe images on my e-commerce website are watermarked with an aspx script, therefore when you are browsing products, if you want to save the image it saves it as aspx rather than jpg or png. The thing is I need to give urls of jpg for a website that advertises products. There are more than 10,000 products so I can't save all of them manually, so I made a page with jquery that get's the image part of the product display page. What this page returns is this:
<div id="result"><div id="loadpic" style="width: 160px;">
<img border="0" src="http://11.11.11.11/img/picsel.aspx?code=IPHONE-32GB-4">
</div></div>
And the output is only an image. How can I return this image not as an aspx page but as a jpg or png? Since there's a script for watermarking the image and making it aspx, shouldn't there be a reverse function?
