# Known issues & Limitations: |
48
|
|
|
# ------------------------------- |
49
|
|
|
# Not so much an issue, the image is destroyed on the deconstruct rather than |
50
|
|
|
# when we have finished with it. The reason for this is that we don't know |
51
|
|
|
# when we're finished with it as you can both save the image and display |
52
|
|
|
# it directly to the screen (imagedestroy($this->imageResized)) |
53
|
|
|
# |
54
|
|
|
# Opening BMP files is slow. A test with 884 bmp files processed in a loop |
55
|
|
|
# takes forever - over 5 min. This test inlcuded opening the file, then |
56
|
|
|
# getting and displaying its width and height. |
57
|
|
|
# |
58
|
|
|
# $forceStretch: |
59
|
|
|
# ------------------------------- |
60
|
|
|
# On by default. |
61
|
|
|
# $forceStretch can be disabled by calling method setForceStretch with false |
62
|
|
|
# parameter. If disabled, if an images original size is smaller than the size |
63
|
|
|
# specified by the user, the original size will be used. This is useful when |
64
|
|
|
# dealing with small images. |
65
|
|
|
# |
66
|
|
|
# If enabled, images smaller than the size specified will be stretched to |
67
|
|
|
# that size. |
68
|
|
|
# |
69
|
|
|
# Tips: |
70
|
|
|
# ------------------------------- |
71
|
|
|
# * If you're resizing a transparent png and saving it as a jpg, set |
72
|
|
|
# $keepTransparency to false with: $magicianObj->setTransparency(false); |
73
|
|
|
# |
74
|
|

# FEATURES: |
75
|
|
|
# * EASY TO USE |

86
|
|
|

87
|
|
|
# - crop - resize as best as it can then crop the rest |
88
|
|
|
# - Force stretching of smaller images (upscale) |
89
|
|
|
