I guess it's a matter of preference, but I find I get better results if I sharpen a little more, then resize - not the other way around. For thumbnails, I use the following code to scale down the image by two thirds at a time, then sharpening: function ratio (newWidth, newHeight) { return (newWidth ...

PNG transparency problem - bug? (example) [GFLAx/ASP]

My goal is to generate and save a semi-transparent PNG. Here's my code: <% Const AX_PNG = 3 Set Pic = Server.CreateObject("GflAx.GflAx") Pic.UseTransparency = True Pic.LoadBitmap Server.MapPath("_trans.png") Pic.FontName = "Verdana" Pic.FontSize = 36 Pic.TextOut "This is a test", 0, 0, RGB(255,0,0) ...

Yes, the edge pixels are not full-intensity red - I also don't want those masked out, so that's not a problem. But look at the code: Pic.MaskColor = Pic.GetColorAt(0,0) The color at 0,0 is the background color, WHITE, FFFFFF ... not red. So white should be masked out - not red. But it doesn't seem t...

I don't see how that could be the problem? it shouldn't matter what's in the image in the first place - since I convert it to 8 colours first, the image has a palette ... normally, when you create a transparent GIF, that's what you do - reduce to x number of colors, then pick the color you want to b...

GetTextWidth bug when string contains "&"

For strings containing an ampersand (the "&" character), the GetTextWidth function returns a size that is too small - as you can see in the following simple ASP example, this is true. <% Const AX_GIF = 2 Const AX_To8Colors = 8 Const AX_NoDither = 0 Const AX_ToColors = 0 BG = RGB(255,255,255) FG = RG...

Anybody else experienced this problem? Anyone know the cause, or know if there's any way to work around it?

I'm trying to do the same thing, but I'm having less luck than you :(

Any chance you could take a look at this post and tell me what you think?

Thanks

transparent GIF problem

I'm trying to generate a transparent GIF with GFLax in ASP, but I've run into a problem. Let's say I do this: <% Const AX_GIF = 2 Const AX_To8Colors = 8 Const AX_NoDither = 0 Const AX_ToColors = 0 BG = RGB(255,255,255) FG = RGB(255,0,0) Text = "This is a test" Set Pic = Server.CreateObject("GflAx.Gf...

here is a quick test, including the source picture for the thumbnails. this may be a somewhat subjective matter, but if you look closely, I think you will see that the straight GFLAx.Resize is somewhat blurred and less detailed than the other two... here's another idea: a designated "thumbnail" fun...

Better resize

I'm using GFLAx in ASP. I am not happy with the image quality when resizing images to very small sizes (e.g. thumbnails) ... I've had to migrate from ServerObjects ASPImage v2.0, which unfortunately is unstable and causes server death. But the thumbnail quality was considerably better - my thumbnail...

oh, and here's the corrected code for placing the "logo.png" in the lower-right corner, on top of the image. With ctrl .EnableLZW = TRUE .LoadBitmap Path & "\logo.png" LogoW = .Width LogoH = .Height .LoadBitmap File .DrawImage Path & "\logo.png", .Width-LogoW, .Height-LogoH .SaveFormat = AX_JPEG .Sa...
