GdPicture Imaging Forums

I've been using GDPicture ActiveX for 3 years, I just upgraded to use GDPicture 10, but the quality of thumbnail is too bad, it looks good if I use GDPicture 5. Please help me to solve this issue.

var nImageID = MyImaging.CreateGdPictureImageFromFile("c:/image1.png");
var nThumbID = MyImaging.CreateThumbnail(nImageID, 46, 60);
MyImaging.SaveAsPNG(nThumbID, "c:/thumbnail.png");

Hi,

Please try using CreateThumbnailHQ instead.


Best,
Sami

I already tried CreateThumbnailHQ but the same result

still waiting for the solution , 1 more note: it only happens with B/W image

noone can help me?

Hi,

Sorry for the delay, please use the overload:
int CreateThumbnailHQ(
int ImageID,
int Width,
int Height,
Color BackColor
)

Also, the values you provided for the thumbnail are too small to produce anything viable on bw images, please at least double the w and h.

Best,
Sami

did you try your HQ method with my image? how about the result? I already set 4 times bigger for h & w, it looks so urgly , can not compare with the last version (v5), the result of v5 looks so good, please remember that we are talking about activex component and bw tiff, I have to upgrade to v10 but in fact that i'm missing v5 so much

btw, I used this image as a sample 3 years ago,it worked well, why now you tell me it is too small , i think this is a bug of activex component
