RE: Image Resize downsampling

2008-08-24T16:26:03-07:00

Well I am using the Image CFC and it has worked well with every test image. However, the one I attached to my post does not work. I try to blur the image first, then I resize it. The image I attached does something strange when it goes through the code. It does not blur, but instead gets vertical lines through it. It does not resize, but instead gets cropped in the upper right corner. (The attached is in this thread)

Aidema, I think you have a better chance to get help if you describe what kind of problems you are having.

imageCFC.convert()

2008-08-24T05:30:36-07:00

Can you convert .bmp files to .jpg using imageCFC.convert()? I guess I should ask, what kind of file type can I convert to .jpg using imageCFC.convert()? I will start trying to answer this one myself but wanted to see if I could get the answer without writing any code. :)

Can someone test the ImageCFC with the attached image?

RE: Error when accessing CMYK jpeg file

2008-08-22T15:26:05-07:00

[quote="DavidSim"]Just to confirm we had run into this problem with the latest release (and all previous ones we have used), with dozens of wrongly uploaded CMYK files being locked (until server restart) by CF threads. This fix worked - might be worth considering making it part of the main release. Thanks to Rick for the CFC which has worked brilliantly for us, and to the poster who supplied the fix.[/quote] I'd love to prevent users from uploading CMYK jpegs in the first place if that were possible...

RE: Not working

2008-08-22T15:21:48-07:00

[quote="mistypotato"]hello, been futzing around with this for several days now and decided I need assistance. I'm using 2.18 on CF 6.1 (WindowsXP locally). I'm using ProFlashUpload for the upload and calling inc_resizeimages.cfm which then calls ImageCFC. The ProFlashUpload part works but for the life of me I can't get any image processing to take place. As far as I can say, all the files are in the proper places etc. The error is [b][Unknown Type][/b], even though the file IS SUCCESSFULLY uploaded. If I remove the inclusion of ImageCFC from the calling structure, the error goes away so it appears to be an ImageCFC issue. I've included the results of the test-cases run. Any suggestions would be appreicated. Thanks, Mr. Potato[/quote] I'm using CFFM in a CMS and my client is getting this same error when she resizes or rotates or scales an image. The image does get resized but she gets the error. I do NOT get it on my end - we are at the same web page doing the updating. I was hoping there was a way to find out why she'd get it while I (and no other clients) do?

RE: Image Resize downsampling

Ah, I think you must specifically tell it to use the .img returned from the filterfastblur, like: imageCFC.crop(imageCFC.scaleWidth(imageCFC.filterFastBlur("", resizeSource, "",blurMe.amount,blurMe.times,100)[color=green][b].Img[/b][/color],"", "",newWidth,100).Img,"",requestedImagePath,1,5,212,134,90) EDIT: Note that that code is also doing a crop, so it is one extra layer there, but the green text is still valid. [quote="aidema"]Well this post answered another one of my questions. I think this will let me perform two operations on my image. However, I'm not able to make this work. Can you tell me what is wrong with my code? newWidth=200; orgWidth=1600; blurMe = getBlurConstants(newWidth,orgWidth); testHeader("6a","call resize() method, standard resize"); try { // standard resize test6a = imagecfc.resize(imagecfc.filterFastBlur("","#ExpandPath(".")#/#srcImage#", "",blurMe.amount,blurMe.times,100)"","#ExpandPath(".")#/#srcImage#","#ExpandPath(".")#/thumbnails/test6a.jpg",200,200,true,false,100); if (test6a.errorMessage neq "") { mydump("test6a error message", test6a.errorMessage); } else { displayResultImage("test6a.jpg"); } } catch(Any e) { mydump("Test Failed",e);[/quote]

What error do you get? Did you include the getBlurBlaBla function?

RE: best quality on resizing image

2008-08-21T20:40:46-07:00

I am new to this CFC and so far its been good. However, I am having problems with the appearance of my image after its been resized. It looks like others are too. What is the best way to solve this? Should I apply the filterFastBlur? If so, how can I do that combined with resize?

That actually works perfectly. Thanks! You're a genius!

RE: Image Resize downsampling

Typically, when you downsize a picture you need to blur it a bit before. The bigger the change, the more you need to blur. I use this function to get data: [code] [/code] If I have a pic 400px on the biggest side and I want to make it 100 on the biggest side I would do [code] newWidth=100; orgWidth=400; blurMe = getBlurConstants(newWidth,orgWidth); imageCFC.scaleWidth(imageCFC.filterFastBlur("", pathToOrigonalFile, "",blurMe.amount,blurMe.times,100).Img,"", pathToSaveResult,newWidth,90)> [/code] I just cut exceprts of code partly out of context - I might not work at all :)

Image Resize downsampling

2008-08-15T09:26:31-07:00

Hi all, I'm currently working on a project that involves producing two smaller images (thumbnails) from one original image. However I found the smaller images to be not as smooth as the original one. I've tried bicubic and bilinear interpolation, without any improvement. Am I doing anything wrong? Cheers, Anthony

"Mapping" question

2008-08-05T21:31:33-07:00

Hi, Am interested in trying out BlogCFM but am a little unclear about the README instructions, step 3 in particular. I already have a website at the root, but want to add a blog separately, under mywebsite.org/blog. Do I have to change the mapping, and will this cause any problem with the existing CF apps running at the root level? thank you, Sarah

RE: Issue with session.captcha_key

2008-08-05T13:50:40-07:00

I am having the same issue. The idea is not to display the session variable via text but just to compare it against the value that the user enters in the text field before the form is submitted with javascript.

Hi.. is it possible to create something like: www.x.com/blogaa www.x.com/blogbb www.x.com/blogcc where aa, bb, cc are usernames (members) of a community. I'd like to setup a community site where a blog will automatically be created for a user once they join the community. What's involved in something like this.. I am a beginner CF person and already own a domain (not X.com, btw). Any help and examples would be very much appreciated thanks! Shemp

RE: Update for TinyMCE?

And of course shortly after posting I find the tutorial in the tinyMCE wiki. Here's the answer: Callback function [code] function cffmCallback(field_name, url, type, win){ tinyMCE.activeEditor.windowManager.open({ url : '/cffm/cffm.cfm?editorType=mce&EDITOR_RESOURCE_TYPE=' + type, width : 850, height : 600, movable : true, inline : true, close_previous : "no" }, { window : win, input : field_name }); }[/code] OpenFile function in cffm.cfm [code]function OpenFile( fileUrl ) { var URL = fileUrl; var win = tinyMCEPopup.getWindowArg("window"); // insert information now win.document.getElementById(tinyMCEPopup.getWindowArg("input")).value = URL; // for image browsers: update image dimensions if (win.ImageDialog.getImageData) win.ImageDialog.getImageData(); if (win.ImageDialog.showPreviewImage) win.ImageDialog.showPreviewImage(URL); // close popup window tinyMCEPopup.close(); }[/code]

Update for TinyMCE?

2008-07-24T20:24:27-07:00

Have you had a chance to look at revising cffm and the associated callback function for the updated tinyMCE editor? edit: I just figured out my real issue is with the "inlinepopups" plugin. If you use regular windows everything works. So my question should be... anyone have luck making all this work using inlinepopups?
