* TODO:
|
| 12 |
*
|
| 13 |
* o) On editing an existing image, set the default crop values to include the whole image [DONE]
|
| 14 |
* o) Need to scale the image to match available width/height [DONE]
|
| 15 |
* o) Add a definition of final resolution [DONE]
|
| 16 |
* o) Add a definition of crop area resolution [DONE]
|
| 17 |
* o) Upgrade to latest imagefield [WORKS WITH 1.2-rc1]
|
| 18 |
* o) On edit node, after preview shows an empty grey box [DONE]
|
| 19 |
* o) Test without 'always show cropping area' [OK]
|
| 20 |
* o) Enforce final size of the image according to widget resolution and cropped box [DONE]
|
| 21 |
* o) After changing crop see the old cropped image on preview [Same with imagefield]
|
| 22 |
* o) What about the delete checkbox? [DONE]
|
| 23 |
* o) Make the resizing box a little faster (ease on JS code) [NOT NOW]
|
| 24 |
* o) Edit existing node, cannot upload new image [DONE]
|
| 25 |
* o) Experiencing some segmentation faults (WSOD) [Probably xdebug related]
|
| 26 |
* o) Not using GD, but imagemagick [TEST]
|
| 27 |
* o) when creating a new node, upload one file, then another, can't crop [DONE]
|
| 28 |
* o) Test with imagefield-2.0 [edit existing node loses the image]
|
| 29 |
* o) NEW NODE: Uploading a file with existing filename shows the cropped image [??]
|
| 30 |
* o) Editing an existing image and cropping again loses the image [DONE]
|
| 31 |
* o) Sometimes we see old file (upload file with exising filename into crop box of
|
| 32 |
* existing node. Probably a problem with 'file_create_path' [??]
|
| 33 |
* o) How to scale without distroting the image? [Force ratio]
|
| 34 |
* o) Do we scale up? [YES]
|
| 35 |
* o) Do we want to use $_SESSION['imagefield'] and save some code? [YES]
|
| 36 |
* o) REFACTOR the code that is duplicated for 'always show cropping area' [DONE]
|
| 37 |
* o) After submitting a cropped image with existing name, the old image is shown [Need to click 'refresh']
